ONETEST-501 II Portable Air Negative Ion Detector-Ambient Negative Ion Measurement
1. Introduction of ONETEST-501 ii air negative ion detector:
ONETEST-501 II air negative ion detector is an economical negative ion detector developed by Wanyi Technology for the measurement of negative ion concentration in indoor and outdoor ambient air. It is especially suitable for the measurement of negative ions in materials for the home improvement market, such as indoor air, negative ion paint, Negative ion concentration released by materials such as plates and fabrics;
ONETEST-501II adopts the universal flat electrode measurement principle, which has the characteristics of good oxidation resistance and fast response. Simultaneous sampling of German imported standard parts and intelligent sampling fans, single-chip system control, so that the instrument can get good stability and consistency! Suitable for the measurement of negative ions in low concentration environments and the evaluation of ambient air! It is a good tool for personal hobbies, travel enthusiasts, home decor, and anion sales assistance!
