Onetest-500xp coaxial double cylindrical precision negative ion recorder

Overview of Precision Negative Ion Recorder
    ONETEST-500XP precision negative ion recorder is manufactured and designed according to the "most accurate coaxial double cylinder type" in the Japanese JIS ion in air Densitometry pointer draft. Compared with the flat plate type ion detector on the market, the accuracy is greatly improved. With RS232 data output, it can record, analyze and print the measured data using a dedicated computer recording analysis piece, which is suitable for forestry, meteorology, ecology Assessment of living environment and testing of identical products.
