Meter

Company Reference: 

The YSI Pro1030 handheld meter measures pH or ORP, plus temperature, conductivity, specific conductance, salinity and TDS. It has user-replaceable pH and ORP sensors, cables and a convenient calibration. Its ruggedness is backed up by military-spec connectors, IP67 waterproof and rubber over-molded case, and 1-meter drop tests. A four-electrode conductivity cell is built into the cable and requires minimal maintenance.

TDS Monitor

Company Reference: 

The TRM-1 is a wide-range TDS monitor, able to measure 0 to 10,000 ppm with three different sensors. It is ideal for water filtration/purification systems that require three sensing points, such as RO/DI systems. Each sensor is ¼ in. in diameter. The monitor comes with three ¼-in. quick-connect T-fittings. It is battery powered, has automatic shutoff, automatic temperature compensation and an accuracy of ±2% (of the reading).
 

Meter

Company Reference: 

The COM-80 is an economically priced, water-resistant handheld tester for electrical conductivity and TDS, featuring four built-in modes (μS, mS, ppm and ppt). It also includes onscreen diagnostic messaging and temperature on a large four-digit LCD. The tester was co-designed in the U.S. and Korea and is backed by a one-year factory warranty.

Sper Scientific

For more than 25 years, Sper Scientific has manufactured and distributed precision measurement instruments, including meters for testing a variety a water quality parameters. These include handheld, benchtop and pen-style meters for reading of pH, conductivity, salinity, mV, ORP and more.

Achieving Accuracy

There are many portable handheld devices that measure dissolved solids, but not all instruments are equal. Beyond the product specifications, how can you tell which instrument to choose? Even when you choose the best instrument, how can you get accurate repeatable readings? This article addresses design and use issues that affect the accuracy of conductivity, resistivity and total dissolved solids (TDS) measurements so that you choose the right instrument for your application and use it correctly.

What’s in the Water?


Water testing has certainly evolved from the ancient days of tasting and swirling water in the mouth like a good wine. Taste and odor are parameters that have taken on new meaning. What’s in the water? How did it get there? Is it harmful? Is it regulated? What are the limits of exposure, and what can be done to rid the water of undesirable contaminants?

Many contaminants are odorless, colorless and tasteless, and can only be detected by chemical testing.

Beating Bottled Water

Everyone wants pure drinking water, but traditional point-of-use (POU) purification systems sometimes drive consumers toward bottled water. Pitcher-based filtration systems remove few contaminants. Conventional RO systems treat water at low flow rates and generally require a storage tank. Another factor is taste. For example, RO filtration systems remove nearly all of the minerals that contribute to taste.
