Ideal for space-constrained applications, this RTD probe to USB adapter measures 100 Ω Pt100 and communicates with the instrument in virtual COM port mode. Moreover, this calibratable adapter provides ±0.009°F (±0.005°C) accuracy temperature measurements using a 2/3-wire sensor connected via a standard 3-pin mini RTD connector.

The RTD300 is a universal converter for Pt100-type RTD probes with 2 or 3 wires. It can be combined with the RTD probe offered by Dracal, which is pre-wired for optimal use with the RTD300. However, since this device comes with a probe connector, you have the flexibility to choose a compatible probe of your choice.
Using state-of-the-art chip technology, the RTD300 delivers unparalleled accuracy and resolution for your temperature readings across a broad range. It is the most precise among the range of USB converters for RTD probes available from Dracal.
Like all Dracal measuring instruments, this device is compatible with free software tools, making it an essential component of a DAQ solution. For those looking to integrate the RTD300 into their system, two options are available: command-line tools and VCP mode. If you prefer a graphical interface, DracalView is the appropriate choice.
