The Kanomax Climomaster™ series is a collection of multi-function thermal anemometers capable of measuring air velocity, and air temperature, with optional differential pressure relative humidity.

The Kanomax Climomaster™ series probes have many great features and are very versatile. The Kanomax probes have an EPROM with calibration data stored in the grip section of the probe which enables you to use the main unit with multiple probes, allows a spare probe to be used when necessary and allows for easy replacement. This is especially useful during recalibration periods and prevents meter down-time.

The Kanomax Climomaster™ series have an automatic flow rate calculation function, RS232C terminal for data logging, can store up to 1500 measurement data readings and models are available with differential pressure measurement as an option.

  • Differential pressure option may extend lead time. Please call for availability

Kanomax Climomaster™ Series anemometers ship complete with meter, probe, operation manual, carrying case, AA batteries and 2m cable probe.
