TR-51i Data-logger with Internal Sensor and IR Connectivity
The data recorded by the loggers can be transfered to PC via separately sold "Communication Port TR-50U2" or "Data Collector TR-57DCi", whereby users can analyze the data and view in graph form.
Furthermore, our Data Collector TR-57DCi enables on-site data collection and viewing of data; no longer it is necessary to manually gather the data loggers.

|(*1) The included lithium battery (LS14250) is not sold in stores. Please purchase the optional battery set (TR-11P2) for replacement.
(*2) Battery life depends upon the measuring environment, recording interval, and quality of the battery being used. When infrared communication function is enabled, battery life may be further shortened if the unit is used under the inverter type fluorescent lighting.
(*3) This is the waterproof capacity of the data logger with the sensor connected.
