Thermo-Hygrometer BC21 - TROTEC

The BC21 instrument combines four essential functions within a single compact housing: measurement of relative humidity, ambient temperature, dew point, and wet-bulb temperature. Whether for home, workshop, or professional spaces, it allows for quick analysis of climatic conditions and anticipation of corrosion risks or mold development.

Reliability and Robustness

Equipped with a stainless steel probe designed to withstand impacts and repeated bending, the BC21 ensures optimal longevity even in demanding environments. HVAC and ventilation professionals particularly appreciate this tool for planning, adjusting, and monitoring installations. Dew point and wet-bulb temperature measurements provide comprehensive analysis of indoor thermal comfort.

Ergonomics and Practicality

The dual simultaneous display allows multiple parameters to be viewed at once. The min, max, and Hold functions facilitate tracking of variations. The probe's responsiveness, backlit screen, and accessible touch controls ensure intuitive handling, including one-handed operation. Automatic standby extends battery life.
