TR-81 has been designed for use with any three-wired Pt 100-type sensor. Can be easily attached to already fixed sensors. Wide range of uses from personal to business.
If the attached sensor becomes wet for a short time, it can still be used again by drying it quickly at room temperature.
If a not sufficiently dried sensor becomes wet again even for a short time, the sensor life may be adversely affected.
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.
A TR-81 is capable of recording up to 8,000 data sets. (One data set consists of readings for all channels in that type of unit.) 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.
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.
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.
We have eliminated the worry of losing data due to a loss of power.

ENDLESS: When the recorded data goes over 8000 units the oldest data is overwritten and recording continues.
ONETIME: When the recorded data reaches 8000 units the REC indicator goes off and recording stops.
