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-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-52A gives you fifteen recording intervals (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.
