Each RIU has two internal relays. The relays can be programmed to send alarms or control a device (e.g. a solenoid valve for oxygen control).
Standard probe options:
- OxyGuard Commander galvanic DO/Temp probe
- In-Situ optical RDO Pro-X or RDO Blue probe
- OxyGuard DO probe
- OxyGuard precision temperature probe
- Sensorex differential pH Sensor
- OxyGuard salinity meter
- Sensorex differential ORP Sensor
