Traceable® Precision Thermometer/Clock/Humidity Monitor with Graph


Unique unit simultaneously displays time of day, temperature, and humidity. Clock displays AM/PM or 24 hour military time to the exact minute with 0.01% accuracy. Noting changes is easy with the triple display. Permits monitoring conditions overnight, on weekends, or any time period.

  • Features Min/Max memory, memory clear, history graph, °F/°C switchable, 12/24-hour clock
  • At the touch of a button, memory recalls the highest and lowest temperature and humidity readings
  • Internal sensors make it ideal for use in hoods, storerooms, cleanrooms, incubators, drying chambers and environmental cabinets

In the default view, the hygrometer will display a graphical history for the selected measurement channel illustrating the range of temperatures sensed each day for the last seven days. The historical minimum and maximum values may not be cleared. They will be automatically overwritten after seven days.

Multi-point calibration on an individually-numbered Traceable® Certificate which 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.
