What it is
Thermo-hygrometer Trotec BC21. Key specifications: air temperature measuring range Da -30 a 100 / da -22 a 199 °C / °F, air temperature accuracy ±1 / ±1,5 °C / °F, air temperature resolution 0,01 / 0,01 °C / °F.
The thermo-hygrometer is an instrument that measures air temperature and relative humidity together, with an analogue or digital display.
What it is for
Used for air conditioning indoor spaces, for dehumidifying indoor spaces and for measuring on site and in the workshop.
How to use it
Position it at the point to be monitored, away from heat sources, direct sunlight and draughts, and wait a few minutes before reading. Check the values over time to see the trend. On digital models, replace the batteries when the display grows dim.
Where it is used
