Features
TRH450: High-Precision USB Temperature and Relative Humidity Sensor for Harsh Environments
The TRH450, a member of the TRH series, is designed for environmental measurements of temperature and relative humidity with enhanced accuracy of ±0.1°C for temperature and ±1.5 %RH for relative humidity. It offers an extended operating range of -40°C 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.

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.
Free data monitoring and calibration software
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
Possible applications

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.
