TDSNA14 Conductivity Solution, 7864.7ppm/14000uS, 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.

98767-26 Traceable See-Through Refrigerator Thermometer Ultra with Calibration; ±0.5°C accuracy at tested points by Digi-Sense

Inexpensive refrigerator thermometers are also ideal for monitoring temperatures in storerooms, labs, offices, hoods, and cabinets. Use the suction cup on the back of the thermometer, or included hook-and-loop strips, to locate it close to materials being observed inside a refrigerator or on other surfaces.

Traceable® Products have an individually-numbered Traceable® Certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.

• Includes NIST-Traceable certificate from our A2LA accredited (1750.01) calibration laboratory
• Large 1/2"H digits update every 30 seconds
• °F/°C selectable
• Features enhanced accuracy

Includes

suction cup, one hook-and-loop strip, battery, and NIST-traceable calibration certificate with data.
