The Sauermann Kimo K-Si-VH3 uses hot wire sensing technology to measure air velocity, airflow and temperature, with the ability to detect velocities as low as 0.00 m/s — something a vane anemometer can't do. This makes it the better choice for sensitive HVAC work involving slow-moving or near-static airflow, where a vane probe would struggle to register a reading at all.
An 80cm telescopic rod with double graduation extends reach into ceiling voids, duct access points and grilles without needing a ladder or repositioning the instrument. Air velocity, airflow and temperature are all displayed together on the two-line backlit LCD, with a velocity range of 0.00 to 30.00 m/s and a temperature range of -10.00°C to 60.00°C.
The IP54 rated housing copes with dusty plant rooms and damp conditions, and the magnetic backing allows hands-free readings by fixing the unit to metalwork. It's UKCA certified and RoHS II compliant.
Battery life on this hot wire model is 20 hours, noticeably less than the 120 hours offered by the equivalent vane model in the range. That's a characteristic of hot wire sensing technology rather than a fault, but it's worth carrying spare AAA batteries on longer jobs.
The choice between hot wire and vane technology comes down to what's being measured — where airflow is slow, intermittent, or close to zero, the K-Si-VH3's ability to start reading from 0.00 m/s gives it a genuine advantage a vane instrument can't match. The telescopic rod adds reach into grilles, ducts and ceiling voids that would otherwise need a ladder, and IP54 protection with magnetic backing makes it a practical tool for site use rather than bench work. Shorter battery life is the trade-off for that low-velocity sensitivity, which is a fair exchange for the accuracy gained on sensitive HVAC jobs.
