Raingauge HEATER KIT - Model TBH-LP

The Hydrological Services Tipping Bucket Heater has been designed for use with the Hydrological Services Tipping Bucket Raingauges. The device is a thermostatically controlled heating element, that raises the temperature of the interior of the raingauge, funnel
and catch to avoid the freezing of the gauge in cold climates with subsequent loss of precipitation records.
When the ambient temperature drops below a preset value (+ 4 Celsius), the snow sensor in the funnel is activated. The heating elements remain OFF until snow is detected in the catch area (funnel). The heating elements are turned on and off to keep the funnel
temperature at the preset Setpoint temperature. (+ 10 Celsius ) This will continue for a minimum preset time (18 mins) after there is no snow remaining in the catch.
The heater will then be switched off and the unit will return to the WAIT mode until triggered by another snow event. The system will be de-activated when temperature drops below (-20 Celsius) or above (+5 Celsius) nominal.
