Temperature/Humidity Clock

Precise quartz-crystal timing with temperature and humidity displays|Includes NIST-Traceable certificate from our A2LA accredited (1750.01) calibration laboratory|With precise quartz-crystal timing and temperature and humidity displays, this clock gives you the information that you need. Clock face diameter is 9" (22.9 cm) for easy viewing at a distance. Temperature and humidity dials are 3" (7.6 cm) in diameter. Bright orange second hand provides superior visibility. 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.
