Environmental measuring instruments

Environmental meters are devices for measuring phenomena such as noise, humidity, light intensity, air temperature and wind speed.

These measures can be divided into three main groups:

monostats (single function meter): thermostat (temperature measurement), hygrostat (humidity measurement), pressure switch (pressure measurement), COstat (CO concentration measurement), CO2stat (CO2 concentration measurement).
transducers: temperature transducer, humidity transducer, thermohygrometric transducer, differential pressure transducer, atmospheric pressure transducer, airflow transducers, CO concentration transducer, CO2 concentration transducer, light intensity transducer, irradiance transducer.
multifunction meters (combining multiple measurement functions in a single device).
