Temperature Measurement

Thermocouple temperature measurement enables stable temperature measurement, as it measures temperatures of contact points.
It is capable of measuring a broad range of temperatures, from low temperatures to high temperatures (-200 to 1300°C). (Please use a sensor suitable for the temperature range to be measured.)
AirLogger™ dramatically decreases preparation time by adopting a wireless design.

Temperature Measurement with a Thermocouple

Since the thermocouple measures the temperature of the contact point of the sensor, measurement can be done stably.
Using a K-type thermocouple, it is possible to measure up to a high temperature of -200 to 1300 deg C.

The wireless design eliminates the need for measurement jigs

Wireless technology allows evaluation of the actual machine
without having to use slip rings or measurement jigs.

The wireless design significantly reduces man-hours for wiring work

AirLogger™ can shorten the evaluation period because it reduces man-hours required for measurement.
Reduction in wiring man-hours will relieve the hassle of routing cables.

Enables measurement from inside a metal housing

If there is a gasket or a window, it is possible to measure by wireless communication even in a temperature test chamber.
With the WM2000 series, you can check the radio wave condition on the software.

Starts Measuring in Just 30 Seconds (WM1000)

The WM1000 has a thorough and simple structure.
You may start temperature measurement 30 seconds after turning the power on.
Case example: Easy wireless temperature measurement (video)

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.
Synchronous measurement of up to 100 units is possible.
 Up to 100 channels in WM1000 series
 Up to 700 channels in the WM2000 series
The measured data can be checked in real time with standard software.

PC Communication Unit Max. 100 units

Delivering Wireless Measurement that “Connects”

Memory data is stored using the internal memory of the measurement unit and has a recovery function.
(This function is particularly enhanced on the WM2000 series)
The strength of the transmitted and received radio waves varies significantly depending on the way the measurement unit and the PC communication unit are installed.

Ultra-compact and Low Noise, with No Need for an AC Power Supply

Since it is battery operated, it has the advantage of being less affected by power supply noise, which is difficult to remove.
It can be used in a high-voltage environment by installing the housing of the measurement unit with insulation.
(However, extreme care is required under high voltage since it cannot withstand high voltage between channels of the same measurement unit.)


Waterproofness/Dustproof performance is equivalent to IEC standard IP54 compliant. (The performance of the WM2000 series is the use of a waterproof attachment)

Measurement File Format

Measurement data can be output as a csv file. The WM1000 series, which has a simple structure, creates a log file in the form of a csv file.
