TR-81 has been designed to be used with any three-wired platinum resistance type (Pt100-type or JPt 100-type) sensor.
The measuring range with a Pt-100 sensor is between -200°C and 600°C and it is possible to attach and measure with two sensors.
Moreover, we can tailor the sensor's protection pipe length, protection pipe diameter and cable length to suit your needs.
Possible to Measure and Record from-200 to 600°C
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.
1 Unit has 2 Measuring and Recording Channels
You can measure and record with two channels on one unit. Current temperature readings are flashed alternately on the main unit's display giving you up to the second readings on an easy to view display.
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.
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.
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.
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. Reliable Backup Function
We have eliminated the worry of losing data due to a loss of power.
Easy-to-Read Multi-Functional Display
The easy-to-read large sized LCD displays current readings, recording condition, battery life warning, amount of data readings, and unit of measurement among other things.
