Anemometer Testo model 425

ANEMOMETER TESTO

MODEL 425

Among the functional checks that must be carried out in an air conditioning and ventilation system is also part of the one of the air flow speed in the ventilation duct. In fact, a speed and a volumetric flow rate is not properly adjusted can affect indoor air quality. The text hot wire anemometer 425 measures the speed of the air stream and automatically calculates the volumetric flow rate.

Advantages:

temperature and speed measurement as well as calculation of the volumetric flow rate
Fixed removable telescoping probe: maximum length 820 mm, diameter 7.5 mm
the average over time and points calculation
Hold function, min / max value, Auto Power Off
To check if an air conditioning and ventilation system works correctly, among other things it is necessary to control the speed of the air flow and the volumetric flow in the ventilation duct. In fact, if the speed is too low, the exhaust air can not be discharged properly and it is no longer possible to guarantee an optimal air exchange.

Hot wire anemometer text 425 for fast and easy measurement of the speed of the air stream

The hot wire anemometer text 425 allows fast measurements spots in the ventilation duct. The instrument detects the speed of the air stream, calculates the volumetric flow rate and also measure the temperature. Due to its measuring range between 0 and +20 m / s, the hot wire anemometer is the ideal solution especially for measuring low air velocities.
The anemometer hot wire text 425 has a telescopic scope probe. The telescopic extension can be pulled up to a length of 820 mm and the probe tip has a diameter of 7.5 mm.
You have to measure, besides the speed of the air flow, also the volumetric flow rate of an air conditioning system or ventilation? No problem for the anemometer hot wire 425 text! Once you specify the area of the channel, while measures air speed the instrument automatically calculates the volumetric flow rate. The averaging over time and points provides information on the average value of volumetric flow rate, the speed of air flow and temperature.
On the backlit display can be read at any time, the measured values detected momentarily, the min / max values and averages calculated. With the Hold button, you can "freeze" the value currently displayed to compare eg. with another value. And if sometimes you forget to switch off the anemometer, it will do for you the practice automatic shutdown feature. You save energy and the anemometer is always ready for the next measurement.
Well equipped with the right accessories

To be ready to face any situation, we advise you to order with hot wire anemometer also our practical accessories: on request, a bag, a carrying case or a cover TopSafe (to protect the anemometer from water, dirt and shocks).
