Balometer Testo 420 (electronic)
Balometer Testo 420 (electronic). Electronic balometer Testo 420 is a device for setting up ventilation and air conditioning systems. A special housing will allow additional calculation of the volumetric air flow of HVAC systems, for example, in hospitals and office and commercial buildings. By connecting the appropriate probes, the Testo 420 can measure humidity and differential pressure. Built-in flow conditioner and automatic sensor zeroing ensure accurate data acquisition even on swirl diffusers or low pressure ranges. The electronic balometer is equipped with ergonomic handles and a display with a large tilt angle. The large start and stop button on the device body makes it easy to record measured readings. For clear and quick results, the LCD display has a large tilt angle and can be removed for easy reading. When working in poor lighting, you can turn on the screen backlight. One battery charge is enough for 40 hours of autonomous operation, which allows you to take measurements throughout the entire working day without taking forced breaks. Using the mobile application, you can process, analyze information or create reports right on the spot. Working from a smartphone or tablet, you can use them both as an additional screen and for remote control using a Bluetooth connection. All files are saved in .txt format. and they can be copied or sent by e-mail. Assembly and installation of the electronic balometer is simple and quick thanks to the tension rods. The included wheeled case ensures safe transportation. Features: included in the State Register of Measuring Instruments of the Russian Federation FSIS "ARSHIN"; electronic balometer for measuring volume flow, temperature and relative humidity on large swirl diffusers; exceptionally light weight; Precise measurement even on swirl diffusers thanks to the integrated flow straightener; quick installation, convenient management and creation of reports on site using a mobile application.
