Features

Dramatically Improves Operation Efficiency with a Cable-less Design

The wireless design significantly reduces man-hours for wiring work
AirLogger™ can shorten the evaluation period because it reduces man-hours required for measurement.
The wireless design eliminates the need for measurement jigs
Measurement jigs, such as slip rings and embedded sensor prototypes, are not necessary.
Enables measurement from inside a metal housing
AirLogger™ can perform measurement in a temperature test chamber, etc., if there is a gasket or window. The radio wave condition can be checked with the software.

Capable of Real-Time Simultaneous Measurement at Multiple Measurement Points

The measurement units can be synchronized by the synchronization signals from the PC communication unit.
Up to 100 units can be measured simultaneously, and the measurement data can be checked in real time.
PC Communication Unit Max. 100 units
