TR-71U Temperature Data Logger.

Model  Description 
TR-71U  Temperature Data Logger. USB communication.

2 Measurement and Recording.
TR-71U Temperature Recorders are data loggers capable of measuring, displaying and recording temperature. TR-71U has two temperature channels. The data recorded into the TR-71U units can then be downloaded quickly via USB cable to your computer whereby with our exclusive software you can easily process the data into graphs, tables, save to files and/or print it out. Moreover, it is possible to connect more than one unit at the same time.
Wide Temperature Measuring Range -60°C to 155°C.
The external sensor that comes with the TR-71U can measure and record from -40°C to 110°C, while optional sensors can give you a range of -60°C to 155°C. There is an array of optional external sensors to meet your every need.
Large Data Capacity: 8,000 Readings X 2 Channels.
Each channel can record up to 8,000 readings; giving you about one year of continuous recording at a recording interval of 60 minutes.
15 Recording Intervals, 2 Recording Methods.
You can select from 15 recording intervals from one second to one hour. There are also two methods of recording to chose from. One Time Method: Recording stops when 8,000 readings have been recorded. Endless Loop Method: When 8,000 readings have been recorded the oldest data is overwritten and recording continues.
Reliable Backup Function.
When battery power becomes low a battery life warning will appear on the unit's display indicating that the battery should be changed. If within a short time the battery is changed, measurement and recording will not be interrupted and there will be no data loss. If the battery is not changed the unit will automatically go into SLEEP mode whereby measurement and recording will stop but, due to our BACK UP FUNCTION, data will not be lost and will remain saved for up to one year.
