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.
