Hy-Lite Water Quality Indicator Light with Alarm, 50K Ohm, 1/2" and 3/4" NPT

The Hy-Lite water quality indicator light is a low cost indicator of pure water for deionization, reverse osmosis, or distillation systems. Featuring exclusive auto temperature compensation, the Hy-Lite is by far the most accurate "Quality Light" available. With remote and control capability, the Hy-Lite is also the most versatile product of its kind.

The Hy-Lite has green and red LEDs that continuously display the water quality relative to the setpoint. When the water is "good" the green LED is illuminated. If the water purity falls below the setpoint, the red LED flashes. The integral sensor is designed for installation in standard threaded tee fittings. 3/4" MNPT polypropylene fittings are provided with the Light. Unit construction is made of Stainless Steel and ABS.

Hy-Lites are available with fixed setpoints most commonly used in two-bed and mixed bed service DI and other applications. These lights come the following purities, 25K, 50K, 200K, 500K, 1 Meg, 2 Meg, 3 Meg and 5 MegOhm. This light is powered by a plug-in style 12 VDC transformer. Up to 6 Hy-Lite Quality Lights can be powered by a single power supply by connecting Hy-Lites to each other making for a clean install at the wall outlet.

- Transformer: 115VAC to 12 VDC transformer

- Remote Alarm Module: When visual and audible indication of changing water quality is necessary at a separate location, Hy-Lite resistivity indicators can be connected to the RMA. The RMAR will re-alarm at 180 seconds.

- Purity: 50 KOhm

- Connection Size: 3/4" MNPT

- Includes alarm on the light

- Power: 12 VDC (transformer not included)
