Wide range of air temperature, radiant temperature, surface temperature, water temperature and wet bulb temperature sensors.
Indoor environment sensors
Temperature and relative humidity
Psychrometer sensors (wet&dry bulbs) and capacitive hygrometers.
Hot wire and fan anemometer for air speed measurement.
Differential pressure sensors (Delta P).
Lux sensors for portable applications.
Heat flux on walls or soil and net radiometers for radiant asymmetry measurements.
Gas sensors to measure the most common gas (indoor air quality) in indoor applications.
