Temperature Data Logger.

TR-51A Temperature Recorder data logger is compact, water resistant one channel temperature logger. Temperature Range: -40 to +80 °C, Resolution: 0.1 °C.
 TR-51A Temperature Data Logger 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-51A Temperature Logger is outfitted with internal sensor and a water resistant rating for temporary immersion.

Model  Description 
TR-51A   Temperature Recorder data logger

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.
