TDS150/G Conductivity Solution, 150ppm/229uS, 1 Gal 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.

94460-61 Traceable® Two-Channel Digital Thermometer with Calibration; 2 Wire Probes by Digi-Sense

The dual probe design is perfect for monitoring temperature in two separate areas or measure two adjoined areas to insure uniformity. Ideal for cold storage, chemicals, pharmaceuticals, and more. The two channels records the date and time of the minimum and maximum readings, while independently monitoring user programmable high and low alarms. The built-in alarm provides an alert when the temperature readings exceed the pre-set alarm limits, an audible alert will sound and a red LED will flash. If the readings return to acceptable limits, the audible alarm will turn off however, the LED will continue to flash until reset to indicate that during the test period an alarm was reached. Alarm is programmable in 1° increments. Probe is attached to a 3-1/2-ft (1.05 m) micro-cable that permits a doors to close on it; probe and cable are both submersible. Mount meter with included Velcro™, magnetic strips, or use flip-open stand on benchtop.

Model 94460-61 is designed for general-purpose applications.

• Displays date and time when Min/Max temperatures occur

Includes

NIST-traceable calibration report supplied by the manufacture, Velcro® and magnetic strips, and one AAA alkaline battery.
