• Only suitable for the T-1 PRO & T-2 PRO CO₂-controller

S-4 sensor (response speed 20 seconds) - CO2 / light / Temperature / RV

This all-in-a-one sensor simultaneously measures temperature, air air humidity, CO₂ and detects light.
This sensor also features a built-in calibration function to calibrate the sensor at
the hand of the outside air. The calibration menu can only be reached via a CO₂ controller.

Provied with built-in switch that prevents unwanted calibration.
