P860 series analyzer is the online intelligent measurement instrument, which adopting advanced ion current oxygen sensor with single chip technology. N2%=100%-O2%. It has been widely used in the fields of nitrogen separation from air, fertilizer, petrochemicals and biological fermentation.


. New pattern long-life conversion ion current tester with fast response and high sensitivity
. N2 or O2 concentration display
. Checking the sensor working state automatically and unique double-line working change mode extending the sensor's life
. Setting alarm value freely
. High precision, automatic temperature compensation, eliminating the impact of environmental temperature
