These thermometers are ideal for laboratory, field, and process measurements. 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. Perfect-sized unit fits into flasks, cuvettes, test tubes, and beakers. Read temperatures in foods, gases, samples, reagents, water baths, and semisolids. Stainless-steel probe is resistant to most laboratory chemicals. Long stem allows user to make measurements while stirring solutions in deep vessels. Almost unbreakable plastic and stainless-steel construction (no glass or mercury) makes it safe. Brilliant LCD is 1/4-inch-high. Designed for all ovens and incubators. Guaranteed to have at least one year of calibration remaining on certificate.
