More About This Item

This pen-style thermohygrometer offers precise environmental measurements with a temperature range of 32 to 122°F (0 to 50°C) and a humidity range of 20 to 95% RH. The dual-line LCD provides simultaneous viewing of temperature and humidity, ensuring quick interpretation of environmental conditions. Its lightweight, pocket-sized design makes it ideal for technicians, inspectors, and laboratory personnel who require reliable measurements on the go.

Readings stabilize in under 6 seconds, with updates every second for real-time monitoring. Additional features include Min/Max memory, a data hold function, and a protective sensor cap that enhances durability during transport. The included belt/pocket clip provides convenient access during fieldwork or routine inspections.

Each Traceable® instrument includes an individually numbered Traceable® Certificate verifying accuracy from our ISO/IEC 17025:2017 (1750.01) calibration laboratory, accredited by A2LA. Measurements are traceable to SI units through NIST or other recognized national measurement institutes (NMIs) that are signatories to the CIPM Mutual Recognition Agreement. This rigorous validation eliminates the need for separate calibration, saving both time and cost.
