08006-02 Galileo Thermometer; 64 to 80°F (18 to 26°C), 7 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

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.

09035-20 Irreversible 5 to Point Vertical Temperature Label, 219 to 261°F/104 to 127°C; 10/Pk by Digi-Sense

Labels are made up of a series of temperature-sensitive elements sealed between heat-resistant substrates with transparent windows. Each element changes color distinctly as its rated temperature is met or exceeded. The changes to the label are irreversible, providing a temperature history of the surface being monitored. The labels will not delaminate when removed, allowing them to be attached to an inspection report to serve as a permanent record. Ideal for use in the food, automotive, molding and metal working industries. Accuracy is ±1.8°F below 212°F and ±1°F above 212°F. Shelf life: 1 year after date of purchase.

• Used as a quick inspection tool that the product is in usable condition during the shipping and receiving process
• Save time and money due to costly recalls
• Self-adhesive design

TDSNA12.5 Conductivity Solution, 6956ppm/12,500uS, 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.
