Calibrate with confidence using the Tecal “Field” Range of Dri-Block Calibrators

A new range of lightweight dry-block thermal calibrators that operate from 45°C below ambient up to 650°C has been developed by Techne for convenient use in the field.

The three models in the new Tecal F range incorporate the precision control system used on Techne’s Tecal H and S models to provide excellent reliability and accuracy, with a number of improvements such as an enhanced display resolution of 0.01°C and faster heating and cooling rates.

The Tecal 140F operates between 45°C below ambient (typically -20°C) and 140°C with a temperature accuracy of ±0.3°C and a temperature uniformity of ±0.2°C. Heating time to 100°C is five minutes.

All the models are offered with or without RS-232 communications and can be used with a wide range of inserts to suit different probe sizes. Automatic fan cooling is standard, with accelerated cooling probes also available.
