More About This Item

This industrial-grade digital thermohygrometer accurately monitors temperature, humidity, dew point, and wet-bulb temperature—ideal for HVAC systems, cleanrooms, pharmaceutical storage, and research laboratories. Dew point and wet-bulb measurements are crucial for assessing air moisture content, preventing condensation issues, and ensuring stable environmental conditions in controlled spaces. These features make it an invaluable tool for climate-sensitive applications such as manufacturing, food production, meteorology, and environmental research.

Features such as a large, easy-to-read display, an ergonomic design, and an intuitive interface for quick data retrieval make this thermohygrometer very easy to use. The device includes alarm functions for real-time alerts and a portable design for on-the-go monitoring. Its high-accuracy sensors provide fast, precise readings, making it a trusted choice for professionals requiring traceable climate monitoring with certified calibration.

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.

Guaranteed to have at least one year of calibration remaining on certificate.
