Thông tin sản phẩm

Specification:

Humidity sensor	Capacitive, can take condensation (with sensor coating)
Humidity measuring range	0 to 100 % RH
Humidity working range	10 to 90 % RH: Tabletop and wall-mounted indicator, indoor version 10 to 95 % RH: Wall-mounted and duct version (HVAC) 0 to 100 % RH: Wall-mounted and duct version, rod version
Humidity accuracy at 20 °C	±2 % RH: Indoor version and display unit in the humidity range of 40 to 60 % RH, wall-mounted and duct version in the humidity range of 0 to 90 % RH, rod version with Modbus output, (in the remaining range ±3 % RH) ±2.5 % RH: Wall-mounted and duct version (HVAC), rod version (for DC 24 V, 20 °C and 0.2 m/s) ±3 % RH: Indoor version with CO2 in the humidity range of 30 to 70 % RH, (in the remaining range ±5 % RH)
Temperature dependency	±0.03 % RH/°C (typical)
Sensor coating	Sensor coating for the humidity sensor is an additional protective coating, which offers better protection from contaminants for the humidity sensor and in many cases allows for longer service life, especially with particularly contaminated or aggressive atmospheres. With the exception of the indoor version, all devices are equipped with this feature for increased protection as standard.

Temperature (T)

Temperature sensor	Platinum-chip temperature sensor Pt1000 according to DIN EN 60751, (passive also Pt100)
