OPP-SENS® External absolute

humidity temperature sensors
Type Item no. ADG Euro / pc.

OPP-SENS® External humidity temperature sensor HTa-...-OUT
(absolute humidity)
For the measurement of absolute humidity and temperature
outside.
Display and control unit with autoadapt and capacitive
button (option). This enables the NFC function, allowing easy
sensor parameterization via a smartphone.
5-point calibration: linear interpolation of the output
curve over 5 user-defined points. SENSORS
10 offset points: linear shift of characteristic curve the output
signal via 10-level rotary switch.
Captive lid with 8-way positioning.

10 measurement ranges can be set using the rotary switch:
0 – 15g / m³ 0 – 20g / m³ 0 – 35g / m³ 0 – 50g / m³*
0 – 100g / m³ 0 – 130g / m³ 0 – 150g / m³ 0 – 200g / m³
0 – 300g / m³ 0 – 500g / m³ *factory settings
