Measure indoor air quality on heating, ventilation, air conditioning and refrigeration in residential, commercial and industrial environments with this hot wire anemometer from Beha-Amprobe.
The TMA-21HW consists of two parts. The first is a handheld meter which displays results, while the second is a telescopic, extendable hotwire sensor which attaches to the meter via a flexible cable (2.2m in length). As the probe is telescopic, it can be extended up to a maximum height of 1.2m to reach difficult areas.
This anemometer can be used to measure air flow volume in CFM and CMM and measures air velocity in selectable measurement units of metres/second, feet/minute, knots, kilometers/hour and miles per hour. The probe can be also used to calculate relative humidity and temperature measurements to ensure that the system you're testing is efficient and working exactly as it should.
Additional features of this meter include data hold, built-in memory storage for up to 99 records and a large, backlit LCD screen for use in poor lighting conditions.
