    PN-2000-O2 fixed oxygen alarm
    Introduction
    PN-2000-O2 fixed oxygen alarm, using long-life imported electrochemical industry special sensor, suitable for a variety of harsh industrial environments. Optional functions are mainly, high-brightness sound and light alarm; infrared open cover remote control, flammable and explosive environment operation is more secure; wireless data transmission module and multi-function output alarm signal including relay switch quantity alarm output, current 4- 20MA signal output, corresponding to the RS485 interface, provides standard Modbus protocol. Supporting intelligent acquisition and monitoring software, intelligent monitoring management, monitoring data export, real-time data chart, alarm record query, widely used in gas, petrochemical, metallurgy, environmental protection, fire safety testing; hazardous chemical gas testing; municipal, school, Hospital, factory environmental testing.
     
    Feature
    1.Oxygen alarm imported high-performance electrochemical sensor with good anti-interference performance and long service life of more than 3 years
    2.The instrument has: 4-20mA/RS485 signal output (national standard Modbus signal output (RS485 interface), relay output, data recovery, data storage (optional) and other functions, can be equipped with software, connected with computer, automatically generate graphs, View historical data, storage time interval can be set by yourself
    3.On-site large-screen multi-parameter LCD display with backlight, visual display of gas concentration, type, unit, working status, etc.
    4.Independent air chamber, sensor replacement without on-site calibration, automatic identification of sensor key
    5.Full range temperature digital automatic tracking compensation to ensure measurement accuracy
    6.Full software calibration function, users can also calibrate by themselves, with 4 buttons to achieve, easy to operate, graphical dot matrix pure Chinese operation menu LCD interface.
    7.Secondary alarm setting, dual relay signal output: one set of active DC24V output, one set of passive signal output
    8.It can be equipped with infrared remote control. The explosion-proof place does not need to open the cover to set the parameters to prevent the danger caused by the electrostatic friction when the cap is screwed. The instrument and infrared remote control receive up to 8 meters, and the operation is safe and reliable.
