Oxygen concentration meter JKO-25 Ver.3
Ichinen Manufacturing Co., Ltd.
About This Product
The definitive version of oxygen deficiency countermeasures and concentration monitoring. A highly functional oxygen concentration meter. JKO-25Ver.3 was developed to fulfill three purposes: prevention of oxygen deficiency accidents, oxygen concentration management, and various experiments. We have compiled customer feedback from various fields and are equipped with the following excellent performance and functions.
■Product features
・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.
