The High Precision Thermometer has been designed as high accuracy reference instrument for laboratories and a calibration standard for temperature systems. The superb accuracy of the instrument is verified to national standards. This reference thermometer uses a platinum film sensor with sophisticated linearising techniques for high accuracy temperature measurements in the range -30.00°C to +199.90°C, with 0.01°C resolution. Housed in a clean practical enclosure, the instrument is easy to use with only and on/off switch and is lightweight and portable so suitable for use in the field or on the work bench. The kit includes the thermometer, probe, sturdy carrying case and system test certificate - traceable to national standards. It is operated by a PP3 9V battery or an external 9V DC regulated supply.

This desktop thermometer can be used in high accuracy applications and as a reference to check the accuracy of other thermometers with low voltage 9V battery power supply
Mains operated bench mounted thermometer with bright red LED display, switchable °C/F function and RS232 output with options for alarm and USB. Can be used in high accuracy applications and as a reference to check the accuracy of other thermometers.
