This document is the operation manual of ROTRONIC HTO-45 humidity temperature probe. It introduces the product's features, operation methods, installation methods, maintenance methods, calibration methods and specific parameters.
The ROTRONIC HTO-45 is a combined humidity and temperature probe designed for use at normal room conditions. It utilizes a ROTRONIC HYGROMER CK60 humidity sensor and a BAV 99 diode temperature sensor to provide linearized voltage output signals suitable for data acquisition systems. The device operates on unregulated DC supply voltages ranging from 4.8 to 14.4 VDC or 15 to 24 VDC with a current consumption of 4 mA.
| Humidity Sensor Type | ROTRONIC HYGROMER CK60 |
|---|---|
| Temperature Sensor Type | BAV 99 diode |
| Recommended Operating Range (Humidity) | 25..90 %RH |
| Operating Temperature Range | 5..50 °C |
| Humidity Accuracy | ±3 %RH |
| Supply Voltage (4.8-14.4V) | 4.8 to 14.4 VDC |
| Supply Voltage (15-24V) | 15 to 24 VDC |

Energizing of the probe is required for only 0.5 seconds during each measurement.
The outputs provide 0...1.0 VDC corresponding to 0 to 100%RH and 0 to 100 °C.
Do not connect a load with an impedance of less than 1000 Ω.
For maximum accuracy, calibration may be verified every 6 to 12 months.
