TDSK111900 Conductivity Standard Solution, 111.9mS (Qt) 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.

CD610 TDS Tester with ATC and 1 point manual calibration by Milwaukee

The Milwaukee CD610 Total Dissolved Solids High Range (PPM) Pen is designed for aquariums, pools and education and many other applications. The CD610 helps make sure that you keep your fish tank water clean and healthy. It is a cost effective tool for teacher's science labs. Keep PPM in your target range to help your achieve better results.

DESIGN FEATURES

• Measures Total Dissovled Solids (PPM) direct and with automatic temperature compensation.
• Ideal range for aquariums and pools (0 to 10000 ppm).
• Units in ppm easily convertable to μS/cm.
• 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/PPM 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 TDS TO EC

The Milwaukee TDS/PPM Pen, like all TDS meters, provides a reading measured in parts per million of contaminates per unit of volume in a solution.

TDS/PPM is often converted to uS/cm. Different scales include the 500 scale, 650 scale and the 700 scale.

Your TDS/PPM reading can be approximately converted to μS/cm as shown in the examples below.

1 ppm = 2 μS/cm on the 0.5 factor scale

1 ppm = 1.43 μS/cm on the 442 scale or .70 factor scale
