The OxyGuard Model 420 can be connected directly to a wide range of equipment that can accept a 4-20 mA input, such as alarms, indicators, controllers, recorders, PLC's, PC systems with A/D input etc.
The Model 420 can also be used to measure gaseous oxygen concentration.
Technical Advantages
- Extremely high stability - zero adjustment is never needed, calibration seldom
- No regular maintenance needs. The robust membrane, 50 µ thick, is easily cleaned, but if damaged can be replaced by anyone - at negligible cost
- Correct measurements with flow as low as 1 cm/s
- Based on a chemical principle superior to that of traditional DO probes
- Galvanic type - True zero
- Built-in temperature compensation
- No practical limit to cable length - extension can be made with any type of cable
- Wide range of armatures and fixtures - e.g. the Air Alarm for worker safety in areas where fluctuating oxygen levels could occur in the air, a Flow Cell for measuring gases etc.
- Wide range of accessories - e.g. the EasyCal calibrator, OxyClean compressed air cleaner etc.
