This model measures temperature, relative humidity and dew point temperature using an outdoor COMET Digi/E series probe. Its response to the temperature or relative humidity jump is significantly faster than by models with internal sensor. This model is often utilized to monitor areas in which only the probe is installed, whereas the main unit is installed elsewhere. When monitoring remote areas, the maximum probe line wire must not exceed 15 m. The Digi/E series probes provide calibrated measurement values. Hence, they may be replaced without having to modify the device setup.
The battery in the device cannot be charged.
