OEM Oxygen Meter - PICO2-OEM

  • Optical oxygen meter - OEM module
  • UART interface
  • 1 Oxygen channel
  • 1 Temperature channel
  • Dimensions 59 x Ø17 mm
  • Works in gas (%O2) and in liquids (DO)
  • Very low power consumption
  • Optional USB adapter cable



The PICO2-OEM is an ultra-compact fiber-optic oxygen meter intended for OEM applications. The technical performance of the PICO2-OEM is identical to the USB-device PICO2 with two principle differences:

(1) The PICO2-OEM additionally offers a temperature port for standard Pt100 temperature sensors for automatic temperature compensation of the oxygen measurements.

(2) The PICO2-OEM has no integrated USB-port, but it offers a standard UART interface for integration in custom electronics. However, we offer an optional USB adapter cable PICO2-USB including a licence for the Pyro Oxygen Logger software. When connected to this USB adapter cable, the PICO2-OEM can be comfortably configured and operated with a PC using the versatile Pyro Oxygen Logger software.
