TRH320: USB Temperature and Humidity Sensor for Precise Measurements in Various Environments
The TRH320, a member of the TRH series, is a USB sensor designed for environmental temperature and relative humidity measurements. With a probe operating range from -40°C to 70°C and an accuracy of ±0.3°C (20°C to 60°C) for temperature, as well as an accuracy of ±2.0% RH (0 to 80% RH) at 25°C for relative humidity, it offers high precision for various applications. Its compact probe is equipped with an integrated filtration membrane for additional protection against dust. Powered by USB, it can be used in a relative humidity range of 0 to 100% RH, with a resolution of 0.015°C for temperature and 0.01% RH for relative humidity. Its 1-meter USB cable provides excellent installation flexibility.
Easy to use in your applications
- Virtual COM option (VCP)
- dracal-usb-get: command-line data integration tool
- dracal-sensgate-get: command-line tool for wireless access to sensors connected to a SensGate
- RVCP: REST API for wireless access to VCP instruments connected to a SensGate
Multiple integration and code examples, including Python, C, C++, Java, Node.js, C#, Grafana and LabVIEW.
Application examples
LIMS integration (Tetra Lab Monitoring solution)

Probe filters
- First filter material: Polyethylene terephthalate (PET) mesh
- Second filter material: PTFE membrane

Free data monitoring and calibration software
Like all Dracal measurement instruments, the TRH320 is compatible with free software tools, making it an essential component of a DAQ solution. For those who wish to integrate the TRH320 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.
Be instantly operational with DracalView: Dracal's free data visualization, logging and calibration software
- Works under Windows (Win7/8/10/11 64&32-bit), Mac OS X and Linux
- Simultaneous visualization and logging of an unlimited number of sensors
- Automatic synchronization with Dracal's Wi-Fi gateway
- Easy calibration mechanism open to the end-user

Note
*This product can operate at 100 %RH but is not waterproof. Protect the sensor and CPU against direct exposure to water or snow. Extra housing may be required depending on the application.
**It is recommended that the probe be installed pointing down to reduce the risk of water infiltration or build-up in the probe.
