Benefits

Easy to Install

• Plug and Play: No need to worry about space to remove the lamps, these are air mounted and are removed by opening the front of the unit.

Easy to Maintain

• Non-Contact Maintenance: The air mounted lamps and sensors can be removed without the operator being in contact with potentially contaminated water.
• Self-Cleaning Quartz Sleeve: The mechanical wiper means there is no need to worry about fouling or pulling out the quartz sleeve to clean it. It is also easy to inspect.

Less Annoying Alarms

• Built-In Temperature Control: Prevents alarms from lamps/water overheating.
• Quartz Sleeve Wiper: Reduces alarms from quartz sleeve fouling.
• Air Mounted Sensors: Eliminates alarms from fouled sensors.

Easy to Monitor

• Dry Contacts: Includes 2 dry contacts for easy alarm setup.
• Colour Touch Screen Interface: Remembers the last 99 messages with a time stamp.
• USB Port: Ideal for data loggers.
• Optional 4-20mA Output & MODBUS Connectivity: Available for advanced monitoring.
