[4-3  & 4   Stem |  -67 to 300 degree F]

[-58 - 302 degree F |]

Scientific thermometer is ideal for critical experimental requirements, quality control, and routine measurements. Unit reads in degree C and degree F. Expanded temperature range covers -58 to 302 degree F and -50 to 150 degree C. Resolution is 0.001 degree. Accuracy is +/-0.05 degree C between 0.0 to 100 degree C. Unit conforms to ITS-90, International Temperature Standard: Instant memory key recalls minimum and maximum readings over any time period. HOLD button freezes display for reading later. For ease in reading, a key changes the display to show one, two, or three significant numbers after the decimal point. Internal data logger capture the minimum and maximum temperatures every hour for 24 hours. This temperature monitor shows exactly when a reading occurred. High precision makes this thermometer ideal for measuring temperatures in cuvets, gas systems, reagents, chemical solutions, soil, water baths, ovens, incubators, pharmaceuticals, petroleum products, foods, and wastewater. Designed for years of reliable service even in severe environments. Large, 1.27 cm-high, bright, high-contrast LCD makes the thermometer easy to read. Membrane keys provide a splash-proof design. Lightning-fast temperature changes: The fast-response probe supplied with the unit displays even the slightest temperature change instantly. Readings are updated three times a second. Universal, stainless-steel probe is triple purpose for liquid, air/gas, and semisolids. Accurate readings with tip penetration of 0.84 cm. Probe has a diameter of 0.32 cm, stem length of 16 cm, an overall length of 23 cm and a cable length of 163 cm. Traceable to NIST for accuracy: To assure accuracy an individually serial-numbered Traceable Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. Measures 8.9cm width by 14cm height by 3.2cm thick. Weight is 226.8 g. Supplied with probe, 9-volt alkaline battery, plastic carrying case, and Traceable Certificate.
