TECNOCONTROL is glad to present the new gas detector selection called "BETA" for domestic use with replaceable sensor. When the period indicated by the manufacturer is over, the gas detector will advice about the deadline of the sensor module which will be replaced right away with a new module already calibrated. BETA detectors satisfy the rules in force that concern the domestic gas detection: EN 50194 (methan and LPG) and EN50291 (CO).
