The Many Uses And Functions Of A TDS Meter


A TDS meter of Total Dissolved Solids meter indicates the the total dissolved solids in a liquid sample. It does just as the name states. A TDS meter will give you the total concentration of dissolved solids in the sample of water being tested.

Just like many of the meters that are used to test samples of water, the TDS meter is ultimately, another tool used to test the total conductivity of the water sample. As the dissolved solids that are ionized such as minerals or salts in water can increase the conductivity of a sample, it is used to estimate the conductivity of the sample and gives the total dissolved solids from that estimate.

There are solids that do not significantly affect the conductivity of a sample of water  such as sugars and very small solid particles. Therefor a TDS meter will not include these solids in its reading of a sample of water.

The uses of a TDS meter

There are many uses of a TDS meter, both commercial and residential uses. You may even find that you should be using a TDS meter in some aspect of your life. Even if you have never used or even seen a TDS meter before.

Fish Tanks

The first use for a TDS meter is a very popular use. At least it is a very popular use among fish tank owners. Fish require a certain TDS or total dissolved solids that is similar to the natural environment to which that type of fish originally lived.

The specific requirement of TDS varies with different types of fish. Fresh water fish require a TDS of less than 400ppm or parts per million. Then some fresh water fish require even less than that. Meanwhile, salt water fish require a TDS of as low as 5000 ppm and as high as 50,000 ppm. This varies drastically from freshwater fish.

Many fish owners use a TDS meter to take readings of the water in their aquariums and make sure that the TDS or total dissolved solids is in the range that it should be to keep their fish alive and healthy.


A TDS meter is very useful when it comes to hydroponics. It can measure the nutrient concentration of a hydroponic solution which can be an indication of health.

Pools and Spas

A TDS meter can be used to measure the total dissolved solids of both pools and spas. The lower the TDS, the better. A low TDS reading or lower parts per million (ppm), can help to reduce algae blooms, maintenance problems, and even skin irritation.

The TDS meter

There are many uses for a TDS meter both residential and commercial uses. There are also different levels of TDS meters as well. If you are looking to purchase a TDS meter for any of the uses indicated above, the best way to find a good meter is to go online. Search for TDS meters and you’ll find that there is a whole list of websites that manufacture and sell TDS meters.

Solar Power Tips and Guidelines

Purchasing a good solar system for your home can be a daunting task if you don’t know what you’re doing. Focus on the practical aspects of the system and do your best to look beyond the marketing efforts. The tips ahead will provide you with information on what you should be looking at when making a purchase:
Solar Power Tips and Guidelines
• Recommendations
You must ask friends, family members or even colleagues whether they have any knowledge working with photovoltaic systems around their homes and solar power in general. Chances are someone might know someone who can give you hands-on experience in the matter and knowledge you will sorely need if you’ve never dealt with this before.

• Manufacturer Warranty
You will need to take a look at the guarantees available from the manufacturer. If they are reputable and they have a good warranty period on the panels that happens to be long enough, meaning nothing less than 25 years, then you can count on it. Make sure you choose a manufacturer which will likely be around 25 years from now however, if you want to make sure you have someone who will honor the warranty.

• Keeping it real
If you have found a system that has a much lower price for the same parameters as a higher-priced alternative, then you may have to deal with lower quality systems than usual and you may not even know it. Good equipment and the installation itself will not be cheap, but it will be well worth the finances you will set aside for it. Check the warranty periods of what you’re getting and focus some research on the company that will do the installation itself. Smaller companies will often strive to reduce their overall costs so they can remain competitive on the market, cutting down some services or corners if things are too rough, so keep this in mind when you’re doing your purchases.

• Certification of Panels
This is something that applies to all solar panel purchases, so make sure you have this certification covered. The TUV IEC 61215 certification shows that the panels have been tested by an independent laboratory and that they meet their advertised specs.

• Panel types
Depending on the type of home you need to work with and the space available, before you needed to focus on highly efficient mono-crystalline solar panels. Nowadays however we can work with polycrystalline panel technologies that give far greater flexibility and efficiency without losing the initiative in making it all tie together. If you have the roof space, you can vary that but you should still keep in mind that the ratio between efficiency and technology should still be considered.

How to Prevent Worker Electrocution


Electrical exposure has been recognized as a serious workplace hazard by OSHA. Behind slip and fall deaths, it is one of the most prominent safety hazards on the job – electrocution accounts for almost 5% of all on-the-job fatalities each year. Exposing employees to electric shock or serious electrocution is tragic in itself because most of these fatalities could easily be avoided with the proper procedures and safety equipment.

OSHA standards emphasize on the design and use of electrical equipment and systems, as well prevention measures used by workers in the worst case scenario situation. One of the best ways to prevent is to understand that electrical hazards exist everywhere and covering these risks with proper procedure may save a life in the future.

This subject is very comprehensive, but I’ve picked out the five of the most useful preventive measures against electrocution for workers.

Top Five Prevention Measures Against Electrocution

Stay Away From Metal Conductors – OSHA regulations prohibit the use of portable metal or conductive ladders for electrical work. I will take that a step further and eliminate all metal steps located within your facility if you work with electrical circuits or wires in your business. A ladder made of wood or fiberglass is probably the best alternative – aluminum is not a good alternative. If you are working specifically near energized power lines, OSHA requires arrangements made with the power company to de-energize the line or cover them with insulation prior to work activity.

Insulation – Certain insulators such as glass, mica, plastic, or rubber can be used to prevent electrical shock. Covering or coating metals and other conductive materials can help stop or reduce the flow of electricity. If you are working in an environment with exposed metal, aluminum, or other conductive material, use any of these insulators to reduce the risk of electrocution safely. Make sure prior to working in high-voltage areas that all wires and power sources are covered with insulators – even the smallest exposure could have dramatic effects.

Guarding – The best type of prevention is the type that occurs prior to work ever being done in the workplace. Placing signs and guards around hazardous electrical elements is one of the most cost-effective ways to do this. Locating and enclosing electrical equipment, exposed wires and conductive areas, or harmful voltage areas will significantly decrease accident potential.

PPE – Personal protective equipment is, usually, the last line of defense. If an accident does occur, this equipment may save your life. OSHA has PPE requirements stated on their website at, but some of the requirements are easy to follow. First and foremost, boots are probably the most important PPE a worker could have because the right ones will ground you from electrical currents. Rubber soles and proper material are needed for certain workplace environments, but rubber insulating gloves, hoods, and sleeves are required. In addition, protective helmets designed to reduce electric shock are also required in some industries or particular job sites. The combination of these individual items helps reduce the risk of electrical shock when accidents do occur.

 Grounding and Circuit Protection Devices – Grounding a tool or electrical system only means that you are creating a low-resistance path to non-conductive material (usually the earth). This prevents the buildup of high voltages that, usually, cause shortages and electrical accidents. Grounding all equipment and electrical systems while operating is required by OSHA, specifically for non-construction applications like manufacturing equipment. In addition, circuit protection devices are recommended as a safeguard against faulty grounding. In the event of a ground fault or overload, the circuit protection device limits (or could stop) the flow of current automatically. Think of it as a kill switch to your safety.
