Dracal USB-PTH450 Atmospheric pressure, temperature and relative humidity sensor with improved accuracy and aluminum probe

Dracal USB-PTH450 Atmospheric pressure, temperature and relative humidity sensor with improved accuracy and aluminum probe

  • Brand: Dracal
  • MPN: USB-PTH450
  • Part #: IPCDAL20001
  • UPC:

Features

PTH450: USB sensor with improved precision for temperature, relative humidity, and atmospheric pressure (±0.1°C/±1.5% RH), equipped with a particle filter and an aluminum tip for harsh environments.

The PTH450 allows for the acquisition of temperature, relative humidity, and atmospheric pressure data in a harmonized manner, thanks to its advanced electronics. As a member of the PTH series, it stands out as the most robust, with its anodized aluminum-coated probe capable of withstanding temperatures of up to 125°C. The compact aluminum probe makes it easy to install in confined spaces, and the integrated filtration membrane provides additional protection against dust.

Furthermore, the probe cable is coated with silicone, making it highly resistant to heat, chemicals, UV radiation, and mechanical stress.

Like all Dracal measurement instruments, the PTH450 works with free software tools, making it an integral part of a DAQ (Data Acquisition) solution. For those looking to integrate the PTH450 into their system, command-line tools and VCP (Virtual COM Port) mode are two possible options. For those who prefer a graphical interface, DracalView is highly recommended.

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.
