Optical Temp meter - OEM module


  • 1-channel OEM device
  • For read-out of optical temperature sensor spots
  • Compact dimensions: 59 x Ø17mm
  • UART interface, very low power consumption

OEM module for optical temperature sensor spots

The ultra-compact Pico-T is a fiber-optic meter for optical temperature sensors intended for OEM applications based on the proven high-precision REDFLASH technology from PyroScience. It features very low power consumption, contactless read-out of optical temperature sensors through transparent vessel walls. 

This OEM module features one optical channel with a PICO-connector, compatible to temperature sensor spots with contactless read-out (must be purchased separately).

Pico-T comes with a standard UART interface for integration into custom electronics. In addition, we offer a USB adapter cable PICO-USB including a license for the Pyro Workbench software. When connected to this USB adapter cable, the Pico-T can be comfortably configured and operated with a PC using this versatile software.

For calibration of the optical temperature sensor, it is possible to solder a Pt100 temperature probe without connector (TSUB21-NC) to the OEM module. 

Innovative REDFLASH technology. The REDFLASH technology from PyroScience is based on the unique analyte-sensitive REDFLASH sensor materials. The REDFLASH sensor materials are excitable with red light and show an analyte-dependent luminescence in the near infrared (NIR). The REDFLASH technology impresses by its high precision, high reliability, low power consumption, low cross-sensitivity, and fast response times. The red light excitation significantly reduces interferences caused by autofluorescent samples. Further, the NIR detection technology significantly reduces interference with ambient light, known from the old blue-light techniques.

LabVIEW library. For customer software solutions, a fully functional LabVIEW library is available in the downloads tab. On request, a respective Python library (in beta version) will be sent to you. Just let us know.
