The TR-55i-P Infrared Pulse Data Logger can be used with voltmeters, flow meters, and passage counters.

Recorded data can be transferred to a PC separately via the TR-57DCi Data Collector or the TR-50U2 Communication Port. From there data can be analyzed or viewed in graph form.


The software included with the TR-5i series data loggers makes it possible to create detailed recording settings. Set the interval at which you want recording to occur and the timing at which you want the recording to start. When monitoring measurements for warnings the LED on the logger will flash and the time of the warning will be recorded.

The included graph application allows easy analysis of the recorded data. All data can be viewed in one graph window, regardless of the data format or from what type of device the data came from. Search and filter to get only the data you need. Data can be output as a text format file (CSV).
