With precise quartz-crystal timing and temperature and humidity displays, this clock provides accurate information about ambient conditions. Large 9" (22.9 cm) diameter clock face with black hour and minute hands and bright orange second hand provide superior visibility. The 3" (7.6 cm) diameter temperature and humidity dials measure temperatures from -37 to 47°C (-34 to 116°F) and RH from 8 to 92%.

Traceable® Products come with an individually numbered Traceable® Certificate provided with each unit, assuring accuracy from our ISO/IEC 17025:2017 (1750.01) calibration laboratory, accredited by A2LA. The certificate indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMIs) that are signatories to the CIPM Mutual Recognition Agreement. Every Traceable® product undergoes an intense vetting process before it can carry the Traceable name, saving you both time and money by eliminating the need for separate calibration.
