Product Description
The N323RHT is a digital controller of temperature and relative humidity. It has three relay type control outputs that can be configured to act as a controller, alarm or timer. The humidity and temperature sensor is not included (it is sold separately). The sensor is protected by a polyamide capsule and has a 3 meter long cable.
The electrical characteristics of each model are presented in the housing of the controller itself, according to the purchase order. It has CE (European Union) and UL (United States and Canada) certificates.
-Input Sensor: Humidity measurement
Range: 0 and 100 % (RH) (see Fig. 1)
Accuracy: See Fig. 1; Repeatability: ± 1 % RH
Hysteresis: ± 1 % RH
Linearity error: << 1 % RH
Stability: < 1 % RH / year
Response time: Around 8 s to reach 63 % of a fast input change. Valid at 25 °C and 1 m/s airflow
- Input Sensor: Temperature
Accuracy: Refer Fig. 1; Repeatability: ±0.1 °C
Range: -20 and 100 °C (see Fig. 1)
Response time: up 30 seconds in slow moving air
- Warm - up: 15 minutes
- Measurement Resolution:
RH: 1 %
T: 0.1º from –19.9 to 119.9º
Note: the equipment keeps its precision all over the range, despite the lack of display resolution in a part of the range does not allow its visualization
