08006-18 Dry Block/Incubator Liquid-In-Glass Thermometer; 0 to 80C, 100mm Immersion, Organic Liquid Fill by Digi-Sense

These thermometers are designed for use in specific applications. These Durac thermometers feature markings that are permanently printed on the glass, individually serialized, and red spirit liquid that has a dark scale contrasts against a white background. Some thermometers are PFA coated for added safety which may cause a slight change in accuracy up to 1 division.

Dry block thermometers - designed for use in all standard heating blocks and water baths with most having arrows indicating critical temperatures.

90309-05 Irreversible 1-Point Square Temperature Label, 140F/60C; 50/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

TDS500 Conductivity Solution, 500ppm/731uS, 1Qrt 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.

98766-06 Traceable Large-Digit Stopwatch/Chronograph with Calibration; ±0.001% Accuracy by Digi-Sense

These stopwatch/timer/chronographs feature extra-tough construction and time-of-day alarm - ideal for industrial and plant use.

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
• Shock-resistant ABS plastic case for rugged durability
• Features AM/PM, date, day, alarm, and clock functions
• Use as a timer or use to display time of day in hours, minutes, and seconds

Includes

One 1.5 V button cell, lanyard, and NIST-traceable calibration certificate with data.
