Oxygen concentration meter JKO-A Ver.3
Ichinen Manufacturing Co., Ltd.
About This Product
Advance to the next era from JKO-25Ver.3. We have updated the JKO-25Ver.3 to meet the requests of many users while maintaining its functionality.
Product features
■Additional functions
・Equipped with auto span adjustment function, no manual operation required (optional selection)
・Display scheduled maintenance date (optional)
- Equipped with atmospheric pressure correction function to prevent false alarms due to typhoons, etc. (Atmospheric pressure sensor is built-in or optional)
■Function inherited from JKO-25Ver.3
・It can be used in the full range of oxygen concentration from 0 to 100vol%, making it possible to measure high concentration oxygen.
・You can check the oxygen concentration in real time on the large LCD.
- Compact and easy-to-hold shape. A soft case is available as an option.
・Alarm concentration can be set in two steps. You can also select the upper and lower limits for each.
-Easy to identify electronic buzzer sound when alarm occurs.
- 2 red LEDs notify the alarm.
・Alarm retention or automatic recovery can be selected.
・It is possible to control rotating lights, solenoid valves, etc. using external alarm output.
・Oxygen concentration can be extracted externally using analog output 0 to 1V.
