TDS70 Conductivity Solution, 70ppm/105uS, 1Qt by Sensorex

TDS/Conductivity instruments and sensors must be calibrated together. For a single-point calibration, select the one solution that approximates the expected conductivity or ppm level of total salts. Mixed Salt standards are the most frequently used in the field to sample naturally occurring water sources, boiler feed water, or cooling tower water. Typical river water, well water, or lake water sample will contain a mixture of several different salts. Sensorex Mixed Salt standards simulate a "Natural" mixture of common salt compounds found in these sources. Sodium sulfate, sodium bicarbonate, and sodium chloride salts are blended to provide a representative value. There are certain applications where Single Salt Solutions are preferred. NaCl Solution is routinely used to calibrate instruments measuring Sea Water or brackish water samples. Reagent grade salt and high resistivity DI water is compounded for accurate results. KCI Single Salt Solution may be used with conductivity meters that read directly in Siemens or Ohms. KCI (potassium chloride) is established as an international calibration standard for conductivity measurement. Choose the conductivity calibration solution that is right for your application.

CD601 Conductivity Tester with ATC and 1 point manual calibration by Milwaukee

The Milwaukee CD601 digital electrical conductivity (EC) Pen is designed for aquariums, aquaculture, pools, water conditioning and many other applications. The CD601 helps you make sure that your water has the right amount of nutrient to help keep fish tanks healthy or helps you keep your filters up-to-date and clean for water filtration. Keep EC in your target range to help your achieve better results.

DESIGN FEATURES

• Measures microSiemens (μS/cm) direct and with automatic temperature compensation.
• Ideal range for aquariums (0 to 1990 μS/cm).
• Units in μS/cm are easily convertable to (ppm).
• Factory calibrated with the ability to recalibrate if needed.
• Automatic Temperature Compensation (ATC).
• 350 hours continuous use (4 x 1.5V batteries included).
• Simple one point calibration.

MAINTENANCE

EC electrodes can develop nutrient build up over time. To miminize build up, always rinse the probe in fresh tap or DI water after every use.

CONVERTING EC TO TDS

The Milwaukee EC Pen, like all conductivity meters, provides a measure of electrically charged ions in a solution and is an absolute measure of conductivity.

EC is often converted to TDS in parts per million (ppm). Different scales include the 500 scale, 650 scale and the 700 scale. However, true PPM can only be determined through chemical analysis.

Your mS/cm reading can be approximately converted to TDS (ppm) as shown in the examples below.

2,000 μS/cm = 2.0 mS/cm = 1000 ppm on .50 factor scale

2,000 μS/cm = 2.0 mS/cm = 1400 ppm on the 442 scale or .70 factor scale
