With the purchase of this appliance you have acquired a precision measuring instrument. Although the
hot-wire anemometer is an extremely complex and sensitive measuring instrument, its sturdy construction means that you will be able to perform precise measurements for many years if it is used properly.
Please read the following information and instructions carefully and ensure that this manual is always
kept near to your measuring instrument.
m Please read this manual carefully before using
the appliance for the first time. It contains im portant safety instructions. Moving the appli ance from a cold to a warm environment (and
vice versa) can lead to the formation of conden sation on the measuring circuitry of the ap pliance. This physical effect, which cannot be
prevented by structural means for any
measuring instrument, leads to false measure ment values. Depending on the temperature
difference, the appliance requires an ‚accli matisation time‘ of approx. 15 - 30 minutes be-
fore the measuring procedure can be resumed.
01. Features
Thermal air speed meter
The measuring instrument is capable of measuring
very low speeds - lower than the so called calm (~1.85
km/h); however, it can also measure speeds designated
as storms (approx. 90 km/h). (Refer also to the general
comparative table of wind velocities)
1.1 Comparative table of wind velocities
< 1,85 km/h Calm
< 9 km/h Light breeze
< 19 km/h Gentle breeze
< 28 km/h Moderate breeze
< 37 km/h Fresh breeze
< 46 km/h Strong breeze
< 56 km/h High wind
< 65 km/h Near gale
< 74 km/h Gale
< 83 km/h Strong gale
< 93 km/h Storm
1.2 Features
• Extra-slim probe, ideal for gratings and diffusers
• Combination consisting of hot-wire and standard
thermistor for fast and precise measurements even
at low air speeds
• Maximum and minimum values with recall function
for recalling a certain value.
• Microprocessor circuit provides for the highest
possible degree of accuracy with special functions
and features
• Very large, easily readable LCD with dual display
- air speed and temperature can be read off simul taneously
• Data hold function: the current measured value can
be „frozen“ on the display
• Power is supplied by a 9V battery
• Compact, light construction - the measuring in strument displays precise measurements as digital
values.
• Measurements with different units of measurement:
- Temperature: °C, °F
- Air speed: m/s, km/h, ft/min, mph, knots
- Volumetric flow rates ft³/min [CFM (cubic feet per
minute)] and m³/min [CMM (cubic metres per mi nute)] are possible.
• Built-in thermistor for temperature measurements
• Long-life components in a sturdy, light ABS housing
• Hard-shell carrying case
• Application possibilities (e.g.): Environmental analyses,
air conveyors, deflectors, cleanroom systems, air-
speed measurements, air balance, fans/motors/blo wers, kiln speeds, cold rooms, paint spray booths, leak
measurements on windows, doors, etc.
