Wireless Temperature Logger WM1000

The wireless temperature logger (data logger) WM1000 sends the temperature data measured by the ultra-compact measurement unit to a PC to display it in a graph in real-time and to save the data. It can be used in areas where thermocouple wiring is difficult, such as on rotating objects, moving objects, or in enclosed spaces. In addition, it can significantly reduce man-hours for wiring work.

Measures Temperatures of Rotating/Moving Objects with Ease

The wireless temperature measurement unit enables easy temperature measurement of rotating or moving objects and wide areas, which has been difficult with conventional products.

Light, Ultra-Compact Temperature Measurement Unit with Excellent Environmental Resistance

The temperature measurement unit is ultra-compact and light, with dimensions of 35 mm (W) x 35 mm (D) x 14.5 mm (H) and a weight of 20 g (including the battery). The operating environmental temperature range of the measurement unit is from -15 to +70°C, and the unit features excellent environmental resistance with IP54 waterproof/dust-proof capabilities and vibration resistance equivalent to JIS D1601 Type 1, Class C, which makes the WM1000 useful in many fields.

Ultra-compact measurement unit

Operating environmental temperature: -15 to +70°C (the measurement temperature range depends on the type of thermocouple.)

Waterproof/dust-proof (IP54)

Vibration resistance equivalent to JIS D1601 Type 1, Class C

Fully Wireless

The temperature measurement unit is powered by a general-purpose button battery, which eliminates the need for a power cable. The measurement unit is fully wireless.

Simultaneous Measurement up to 100 Channels

Up to 100 temperature measurement units can be connected to a PC, allowing temperature changes at 100 points to be monitored in real-time.

Simple Software Specially Designed for Temperature Measurement

The software specially designed for temperature measurement is intuitive and extremely easy to use. Even first-time users and those who have not used the system in a while will be able to start performing measurements immediately.

Starts Measuring in Just 30 Seconds

The WM1000 temperature logger has an extremely simple configuration. Users only need to start the software in their PC and put batteries in the temperature measurement child units (temperature sensor) to begin measuring. It takes as little as 30 seconds from launching the software to starting measurement, making the system convenient for even small measurement jobs.

Runs on Inexpensive General-Purpose Batteries

The temperature measurement unit is powered by a commercially available button lithium metal battery (CR2032), which helps reduce the running cost.

Can be Used in Japan, the Unites States, China, and Vietnam

The WM1000 data logger complies with the wireless standards of Japan and the United States (Japan: Technical Regulations Conformity Certification, US: FCC compliance). The product has been approved for use in China and Vietnam. For the details of compliance, refer to “Regulations of Radio Laws.”


By creating a program using the optional WM1000 Series API software, data of pressure, strain, humidity, etc., measured by other measuring instruments can be synchronously measured in one program.
