Compact / Lightweight / Water Resistant!
The lightweight yet durable water resistant construction allows you to use this unit under the harshest of conditions. It can be reliably used in high condensation areas, refrigerated and frozen environments as well as underground.
The waterproofing is sufficient for most situations, but is not for continued immersion.
Wide Temperature Measuring Range:-60°C to 155°C
The TR-51A with its internal sensor can measure and record from -40°C to 80°C and theTR-52 model with its standard external sensor can measure and record from -60°C to 155°C.
Large Logging Capacity: Up to 16,000 Readings
With one unit you can record up to 16,000 readings. If set at a one hour recording interval that gives you 666 days or almost two years of readings.
Wide Selection of Recording Intervals / Two Recording Methods
The TR-51A gives you eight recording intervals (1 min.-1 hour) to choose from, while the TR-52 stretches those choices to fifteen (1 sec.-1 hour). Each unit allows you two choices of recording method:
One time: when 16,000 readings have been reached recording stops.
Endless method: when 16,000 readings have been reached it automatically overwrites oldest data.
Convenient Battery Warning Display
Calculates remaining battery life and displays a battery warning to indicate the need for a battery change.
Battery life will depend on the recording environment, recording interval, communication frequency, and ambient temperature. Removing the batteries will result in a loss of recorded data.
No Switches means No Fuss / No Mistakes / No Tampering
We have removed all switches from the main unit to assure nothing gets accidentally pushed during use, thus assuring you of no mistakes, no tampering and no loss of data.
Two Types to meet your Needs
We offer two types to fit your needs: the TR-51A with internal sensor and a water resistant rating for temporary immersion and the TR-52 outfitted with external sensor and a splash resistant proof rating.
Battery Life Good for up to Two Years of Continued Use.
Using our specially designed low energy consumption circuit this unit can run on one Lithium battery for up to two years 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.
Low Cost Expandable System
With the TR-5 series any number of main units (TR-51A, TR-52) can be used with just one Communication Port (TR-50C). Hence by simply buying the main unit you can expand your system easily and affordably.
