Overview

The small formaldehyde emission detection chamber adopts a touch control screen as the dialogue interface for human-machine operation equipment, which is intuitive and convenient. Configure control software, in addition to the touch screen function, it also has remote control function, which can achieve system control, multi-stage program setting, dynamic data display and historical data playback, with one click trigger start mode, fault recording, alarm setting and other functions. Full protection devices and system safety operation protection devices make equipment operation more reliable and safe.

Product Details

1、 Product Introduction

Small formaldehyde emission detection chamberThe main parts include: insulation box, mirror stainless steel test chamber, clean constant temperature and humidity air supply system, air circulation device, air exchange device, test chamber temperature control unit, signal control and processing part (temperature, humidity, pressure, time, flow rate, replacement rate, etc.). The temperature regulating unit, circulating fan motor, etc. are placed in the jacket between the inner cavity of the test chamber and the insulation box to reduce the adsorption of formaldehyde and TVOC by the test chamber. All joint parts are sealed, and the test cabin door adopts a self sealing device to ensure positive pressure inside the test cabin and prevent the infiltration of surrounding air.
