How to Best Use the Zero Water Tester for Safe Drinking Water

Best Selling Zero Water Tester

If you are looking for the best TDS water meter, the zero water tester would be among the top brands. This Zero water brand is known for manufacturing high-quality filters and pitchers that guarantee zero TDS and pure drinking water for households at considerably low costs.

And tap water contains different TDS levels and inorganic impurities, such as fluoride, minerals, salts, metals, and chemicals. This raises the essence of testers for most households.

The impurities in your tap water could emanate from old-piping, salts, pesticides, among other sources. The tester allows you to evaluate your different sources of water supply.

To test TDS in the water you need a TDS meter that will measure the level of solid particles per one million particles of water.

But before knowing how to use the zero water tester, let’s answer this basic question:

What is The Ideal level of Total Dissolved Solids in Drinking Water?

Under the Zero Water technologies LLC products, a level of 000 TDS is ideal as the water is fit for consumption. This means the water being dispensed after filtration has zero impurities. Your water supply determines the amount of TDS in your water.

The Zero Water Filter involves a 5 stage filtration process, which ensures that the water is fit for consumption. It a thorough filtration system to maximize the water quality through the following process. This process makes ZeroWater the only filtration system with the capability to extract 99% of TDS equal to the TDS in bottled water.

All the zero water pitchers come with a TDS meter whose purpose is to detect the level of solid parts per million water particles. Once you use the TDS meter, you will be in a position to determine the purification process necessary for your water.

How to Operate a Zero Water Tester

To effectively use the Zero TDS meter:

  1. Uncover the bottom of the meter, press the on/off button and ensure it reads 000.
  2. Pour water in a cup or a jug and insert the uncovered side of the water quality meter approximately half an inch, avoid submerging the meter as this could damage the electronics and distort the meter reading.
  3. Go ahead and note the TDS reading. The number displayed at this point is the level of total dissolved solids in your water.
  4. The zero water TDS meter consists of a hold button and a temperature button. As the name suggests, the hold button holds the number on display, so it is not deleted immediately after emerging from the water, while the temperature button indicates the warmth of your water. Ensure your water is at room temperature or even cooler as hot water could alter the readings.
  5. It is essential to switch off the meter once you are done with the TDS reading and insert the cover to its place. This is to protect the zerowater TDS meter from damage and contamination.

It is worth noting that the Zero water tester is factory calibrated and there is no need to calibrate it yourself. However, the zero water meter does not articulate the substances present in your water supply.

For the zero water tester to perform optimally it is important that it always has a functional battery that you will need to change once depleted. To replace the battery, open up the battery compartment, insert the new batteries which should be either the model 357A or L1154. Check to see that the batteries are properly aligned. If they are properly set up, the tester will automatically upon returning the battery compartment.

In most cases, the zero water filters and pitchers come with quality water testers. This is the company’s policy to affirm their cause of attaining zero dissolved solids parts per million parts of water through their ion-exchange filtration process

What Next After The Zero Water Testing Reading?

After establishing the water TDS reading, you are free to repeat the process before and after the filtration process or you can just do it after the filtration.

If you test the TDS levels before filtration, you can now pour water on the zero water pitcher for the purification process to begin. The products’ filter allows the elimination of all the inorganic impurities present in your water.

A high TDS level reading means that your water contains a high impurities content, which raises the need for the zero water filter or the zero water pitcher.

In case the TDS meter runs out of battery. It is advisable to replace it immediately as this will allow you access to filtered water consistently instead of buying bottled water of similar quality at a higher cost.

In the event you don’t get a zero reading after the filtration process you can remove the filters and dry them off with a clean paper towel then place it on a jug.

Then, run just a small amount of water through each filter and measure the TDS levels with the TDS meter, If the water in the jug shows a reading of 000 there are high chances that either you had not tightened the screws of the filter into their place or you had over tightened the filters removing the black O-ring from its place.

How Does the Zero Water Tester Help attain Zero TDS?

The three major ways of purifying water include distillation, reverse osmosis, or ion exchange.

The Zero water tester involves a deionization process that begins once the water passes through the first filter. This ion exchange technology results in sweeter and higher quality water instead of the traditional filters that use the carbon water filter only.

The ion exchange filter involves a 5 stage purification process. This process ensures that all impurities present in the water are eliminated and leaving very minimal contaminants making the filtered water equal to the purified bottled water.

Through this technology, it becomes easy to attain a zero level of dissolved solids TDS. However, to ensure maximum functionality of the filter products make sure that once the filters and the couplers are screwed in there is a complete seal to prevent any contamination.

Upon filtration, any reading that the zero water tester shown as above 000 means it’s time to replace your water filters.

What is the Essence of the Zero Water 5-Stage Filtration Process?

  • Stage One: Eliminate dust and rust that makes the water cloudy
  • Stage Two: Remove the extra suspended solids
  • Stage Three: Inhibit the growth of bacteria and remove organic contaminants such as pesticides, herbicides, mercury, and chlorine.
  • Stage Four: Remove inorganic components which include metals and non-metals through the ion exchange process.
  • Stage Five: Extract any remaining contaminants while holding the resin in place.

This five-stage filtration process ensures that you get TDS free drinking water. The resultant water quality is equivalent to the bottled water available in the market.

Though the 5 stage process may lead to a slower turnaround time in the end the quality of water justifies the time it takes.

How Long Does a Zero Water Filter Last?

The zero water filter has a longer filter life as compared to the traditional ones. However, once the meter reads 006, it means the time is due to replace the filter.

For most average households, it could take 3-4 months before you replace the filter. However, the filter life is mostly dependent on the purity of your water.

In a district with moderately impure water, the Zerowater filter is expected to dispense 40 gallons of water before replacement.
