Ideal for environmental temperature and relative humidity acquisition, this sensor features an aluminum probe and internal filter that protects against harsh conditions. Moreover, this calibratable ±0.18°F (±0.1°C) accuracy sensor operates with the instrument in virtual COM port mode, and the USB port makes it usable in minutes.

The TRH450, a member of the TRH series, is designed for environmental measurements of temperature and relative humidity with enhanced accuracy of ±0.18°F (±0.1°C) for temperature and ±1.5 %RH for relative humidity. It offers an extended operating range of -40 to 257°F (-40 to 125°C), fine resolution, and robust protection thanks to an anodized aluminum tip and PTFE membrane. Powered via USB with a 1-meter cable, it is ideal for applications requiring precise monitoring in challenging conditions.
Like all Dracal measurement instruments, the TRH450 is compatible with free software tools, making it an essential component of a DAQ solution. For those who wish to integrate the TRH450 into their system, there are two options available: command line tools and VCP mode. If you prefer a graphical interface, DracalView is the appropriate choice.
