Recorder data logger

TR-51AS Temperature Recorder data logger is compact, water resistant one channel temperature logger. Temperature Range: -40 to +80 °C, Resolution: 0.1 °C
TR-52AS Temperature Recorder data logger is compact, water resistant one channel temperature logger. Temperature Range: -60 to +155 °C, Resolution: 0.1 °C External probe.
TR-51AS or TR-52AS Temperature Data Loggers can be used on both normal outdoor conditions and in harsh environments such as underground, in snow and frozen conditions as well as in environments where temperature varies greatly.
TR-51AS and TR-52AS Temperature Loggers are outfitted with internal sensor and a water resistant rating for temporary immersion.

Temperature recorder.

Model  Description 
TR-51AS  Temperature Recorder data logger.
TR-52AS  Temperature Recorder data logger. External probe.

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. Note: 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 Data 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 minute-1 hour) to choose from, while the TR-52 stretches those choices to fifteen (1 second-1 hour).
Each unit allows you two choices of recording method: One Time Method: when 16,000 readings have been reached recording stops. Endless Loop Method: when 16,000 readings have been reached it automatically overwrites oldest data.

*1 The lithium battery (ER3V M) is not sold in stores. It can be purchased through our distributors as (Optional Battery Set TR-10P2) Normal lithium batteries sold in stores (CR2) can be used, but the operating range is reduced to -20°C to 60°C. If you will be using the logger in an environment where temperatures may be lower than -20°C or higher than 60°C, we strongly suggest purchasing and using
the -  Optional Battery Set TR-10P2.
*2 Battery life depends upon the measuring environment, recording interval, and quality of the battery being used.
