Tecal “Field” Range of Dri-Block Calibrators
Techne has developed a range of lightweight dry-block thermal calibrators that operate from 45°C below ambient up to 650°C, for convenient  eld use.
The three models in the Tecal F range incorporate the precision control system used on Techne’s Tecal ‘H’ 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. All models o er RS-232
communications and can be used with a wide range of inserts to suit di erent probe sizes. Automatic fan cooling is standard, with accelerated cooling
probes also available.
