TDSK700 Conductivity Solution, 340.2ppm/700uS, 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.

08006-03 Galileo Thermometer; 64 to 80°F (18 to 26°C), 11 in. by Digi-Sense

Colorful glass thermometer is based on Galileo's theory developed over 400 years ago: in liquid, a body of fixed mass becomes less buoyant as the liquid temperature rises, and more buoyant as the temperature decreases - due to changes in liquid density. As temperature changes, the multi-colored balls rise and fall within the liquid-filled thermostatic tube. Lowest sphere in the top group within the instrument indicates ambient temperature.

• Hand-crafted thermometers
• Non-mercury liquid
• Five floating spheres provide both Fahrenheit and Celsius readings
• Seven inches tall

90308-13 Irreversible Thermostrip Disinfection Indicator, 140F/60C; 24/Pk by Digi-Sense

Thermostrip labels are self-adhering and waterproof color-changing labels that measure the surface temperature of dishware in dishwashing machines. Label indicator will turn from white to black when surface temperature reaches rated temperature, providing reliable proof that the items being washed have been fully disinfected. Helps hygiene managers demonstrate that safety disinfection standards have been met.

To use, attach label to the thickest clean dry dish, place in dishwasher, and run. Remove and retain label as a permanent record of temperature attained as an excellent evidencebase for HACCP. Accuracy is ±1.8°F (±1°C). Shelf life: one year after date of purchase.

• Waterproof - designed to withstand the rigors of a full wash
