TT202: Portable Bimetal Temperature Circular Chart Recorder

The accuracy of a TT202 recorder is better than 2% of scale (range).

For example, a recorder with a range of 0 to 25 °C the accuracy is therefore better than ± 0.5 °C. For a recorder with a wider range, eg. 0 + 45 °C, the accuracy is ± 0.9 °C. To get the best accuracy, a recorder with a suitable narrow range should be chosen.

TT210: Portable Temperature Recorder and TT260: Fixed Electronic Temperature Recorder

The accuracy of both TT210 and TT260 temperature recorder models is 1% of the of the width of the measuring range.

Battery backup

TT260: mains, fixed mounting, temperature recorder

Automatic charging circuit for NiCad battery will secure correct operation of both chart drive and recording for 2-4 weeks after mains failure, depending on actual circumstances.
Optional alarm contacts will also function, but may reduce the working time to 1-3 weeks after mains failure (Fully recharged battery).

Alarm Contacts

TT260: mains, fixed mounting, temperature recorder

Adjustable from the front over the whole range. Hysteresis for alarms: Standard 0.5% of range. Output from alarm(s): Change-over relay(s):
