Techne Tempette® and Tempunit® thermostatic controllers
“Clip on” temperature controllers with mounting clamp suitable for vessels with wall thickness up to 25mm. When the controller is to be used with Techne bath tanks the clamp is unnecessary as a bridge plate is provided. All models incorporate a splash-proof case, coiled immersion heater and pressure circulating pump (except TU-20HT). In addition they are fitted with an adjustable overtemperature cut-out and conform to international standards for radio frequency interference. TE10D, TU20D and TU20-HT models have a low liquid level cut-out. TU-20D and TU20-HT have a built-in RS232 interface which allows them to communicate with the users’ personal computer if required using Thermsoft PC control freeware available from the Techne website.
Techne thermoregulators are designed and manufactured under BS-EN ISO 9001. They conform with all important international RF interference and electrical safety regulations, including the EMC and Low Voltage Directives, and carry the CE-mark.
Model TU-20D features:
- High precision, digital controller with wide temperature range and fine temperature adjustment
- PID controller with bright, LED readout
- Built-in circulating pressure pump with external connections (suction not available)
- Adjustable overtemperature cut-out
- Fitted with bi-directional RS232 interface for programming by a personal computer
- Low liquid protection by float switch

*A lid or layer of polypropylene spheres must be used when operating between 60°C and 100°C, and is recommended for use below room temperature. Above 100°C, a lid must always be used. Accessory cooling is required for operation near or below ambient temperature.
Supplied with both UK and European Schuko plugged mains supply leads. For 230V 50/60Hz single phase supplies.
