TR-81 Pt 100 Thermometer Data logger Temperature Data Logger.

Large Data Capacity
Each channel is capable of recording up to 8,000 readings. At a recording interval of 1 hour that gives you about one year of continual recording. It is possible to change batteries in the middle of a long-term
recording and not lose data.
Easy to Read Multi-Functional Display
The easy to read large sized LCD displays present readings, recording conditions, battery life warning, amount of data readings, and the unit of measurement among other things.
Reliable Backup Function.
When Battery Power becomes Low When battery power becomes low a battery life warning will appear on the unit's display indicating that the battery should be changed. If within a short time the battery is changed, measurement and recording will not be interrupted and there will be no data loss.
If the battery is not changed, the unit will automatically go into SLEEP mode whereby measurement and recording will stop. But, due to our BACK UP FUNCTION
5-8 Month Continual Recording on 1 Battery.
Using our specially designed low energy consumption circuit this unit can run on one Lithium battery for five to eight months of continued use. No need to worry about where you place it, as the battery will allow you to measure and record over long periods of time whether the unit is in transit or in a distant place.
Note: Battery life will depend on the recording environment, recording interval, communication frequency,
and ambient temperature. The above battery life test was carried out using brand new batteries and in no way do we guarantee a battery's life.
15 Recording Intervals / 2 Recording Methods.
Depending on your recording needs you can choose from one of 15 different recording intervals
(1 second to 1 hour). There are also two methods of recording: One-time method: Recording stops when recorded data readings reach 8,000.
Endless method: When recorded readings reach 8,000 the oldest data is overwritten and recording continues.
