GUARDIAN™ Ultraviolet Monitors

The GUARDIAN™ Ultraviolet Monitor is available in two models: Digital [Mounted Directly], and Digital Remote [Mounted Remotely] that can either be purchased and installed with the water purifier, or at a later date for an existing installation. View our GUARDIAN™ Ultraviolet Monitor Comparison Chart.

The GUARDIAN™ Ultraviolet Monitor visually indicates the level of germicidal ultraviolet energy that penetrates the quartz sleeve and water within the water purifier. The use of an ultraviolet monitor is recommended by the United States Public Health Service in “Criteria for the Acceptability of an Ultraviolet Disinfection Unit.”

The GUARDIAN™ Ultraviolet Monitor will detect reduction of ultraviolet levels due to:

• Fouling or deposits on the quartz sleeve.
• Poor ultraviolet transmission through the water. Color, turbidity, and organic or other impurities in the water can reduce or interfere with the transmission of ultraviolet rays
• Lamp outage, component or power failure
• Depreciation of the lamp output due to usage or other cause. Lamp output gradually depreciates with use. Lamp replacement is recommended once a year or every 10,000 hours.

Digital GUARDIAN™ Ultraviolet Monitor includes SWITCH SETTINGS that control an INTERNAL AUDIO ALARM and the Solenoid Output. There are 4 settings, two of the settings have 2-Minute TIME Delays of power to the Solenoid Output.

Digital GUARDIAN™ Ultraviolet Monitor is available in two Low Voltage Models a 12v Model, and a 110/220v Model which uses a multi-plug configuration 12v adapter to operate.

This model also provides several outputs from an RJ45 modular jack for remote monitoring of the water purifier’s operation:

• 4-20mA Output: Provides current for remote display of ultraviolet intensity
• Dry Contacts: Provides contacts for remote indication of ultraviolet trip levels
• 12v DC Output: Provides power for a low-voltage external audio alarm

The Digital GUARDIAN™ Ultraviolet Monitor is available in two mounting configurations: Mounted Directly to the water purifier or Remotely. Mounted directly onto the water purifier, the sensor probe is installed into the sight port fitting of the water purifier. The collar on the bottom of the GUARDIAN™ Ultraviolet Monitor is secured over the sensor probe. Older model water purifiers may require a reducing bushing to properly mount the newer sensor probes. If unsure whether the reducing bushing is required, contact the factory.

An RJ45 modular cable is required to interconnect between the GUARDIAN™ Ultraviolet Monitor and other remote monitoring devices. An RJ45 modular jack adapter might be needed to interconnect the RJ45 cable and a remote monitoring device. The RJ45 modular jack adapter and the RJ45 modular cable are not included with the purchase of the GUARDIAN™ Ultraviolet Monitor and if required, may be purchased separately. The cable is available in three lengths; order the one which is best for your application (25ft., 50ft., or 100ft.).

A Digital GUARDIAN™ Ultraviolet Dual Monitor Kit is available for the SANITRON® S5,000C, which includes 2 Monitors, one for each chamber. This allows the Monitors to react to each UV chamber independently, but they will work together to shut down water flow if UV falls below its trip point.

Digital Remote Mount GUARDIAN™ Ultraviolet Monitor: Intended for use in locations away from the water purifier it is monitoring. In all other respects, the remote monitor operates in the same manner as the standard Digital Direct Mount GUARDIAN™ Ultraviolet Monitor. The ultraviolet sensor, instead of being mounted inside the monitor, is mounted in the sturdy, waterproof main sensor body, which when coupled with the lower sensor body becomes the remote sensor probe. A Remote Probe cable connects the remote sensor probe to a socket located on the back of the monitor. The standard cable length supplied with the digital remote monitor is 10 meters (32.8-feet). The cable length may be extended. Please contact the factory with specific requirements.

GUARDIAN™ Ultraviolet Monitors have outputs to control the operation of an optional Promate™ Solenoid Valve and/or optional Promate™ Remote Audio Alarm.

GUARDIAN™ Ultraviolet Monitors are for use with the MIGHTY★PURE® ultraviolet water purifiers, 3-20 GPM, (NSF Certified Purifiers Available), and with the SANITRON® ultraviolet water purifiers, 3-416 GPM, (NSF/ANSI 61&372 Certified).
