Testo® 425 - Thermal anemometer with permanently connected flow probe

In order to determine whether an air conditioning or ventilation system is working properly, you must check, among other things, the flow rate or volume flow in the ventilation duct. This is because if the air flow is too low, the room loads will not be dissipated correctly and optimum room air quality can no longer be guaranteed. Thermo-Anemometer testo 425 for simple and fast flow measurement The Thermo-Anemometer testo 425 enables fast spot measurements in the ventilation duct. It records the flow velocity; calculates the volume flow and also measures the temperature. With its measuring range of 0 ... +20 m/s, the anemometer is particularly suitable for low air flow. The thermo-anemometer has a telescopic flow probe. The telescope can be extended to a length of up to 820 mm and has a probe head diameter of 7.5 mm. You would like to determine the flow rate as well as the volume flow at the air conditioning or ventilation system? That's no problem for the testo 425 thermo-anemometer. When you enter the duct area, it automatically calculates the volumetric flow during the flow measurement. Time and point averaging provide information about the average volume flow, flow velocity and temperature measured value. On the illuminated display, you can read the current measured values as well as min/max and the calculated average value at any time. With the Hold button you can freeze the current measured value, e.g. to compare it with another value. If you ever forget to switch off the anemometer, the auto-off function will do it for you. This saves your batteries and your thermoanemometer is ready for the next measurement. Well equipped with the accessories for the anemometer If you want to equip yourself for all cases; we recommend that you also order our practical accessories when purchasing the anemometer: We offer an optional standby bag, a carrying case or even the TopSafe protective cover (to protect the anemometer from water, dirt and shocks).
