PicoM single channel signal conditioner

Full featured, plug and play, 50 Hz sampling rate in a robust packaging.

The PicoM is a compact and portable signal conditioner to be used with Opsens’ GaAs OTG-M series fiber optic temperature sensor.

At the heart of the PicoM is the Opsens’ Semiconductor Band Gap (SCBG) technology which provides a mean for making accurate measurements of the temperature-dependent bandgap position of GaAs crystal.

The PicoM is equipped with a large visible LCD display and can be battery operated. It comes with a standard ± 5 V output and a RS-232 communication port for real-time data acquisition. The PicoM can be controlled directly using the front-panel keypad or remotely using the standard RS-232 interface. A rugged casing with a removable rubber boot provides good mechanical protection against intensive handling in tough environments.

With a 50 Hz sampling rate and a ± 0.3 °C accuracy (total accuracy including both signal conditioner and sensor errors), the PicoM delivers the performances needed for a wide range of medical measurement applications.
