The DI Inline Tee is a replacement for your DI Resilite. The PVC Tee provides light indicators to show that the water resistivity is above or below the threshold value. The red and green lights can be read at a glance, making it an economical method of monitoring water quality. The LED output and solid-state circuitry outlast conventional neon lamps.
- Green light = water resistivity is above the threshold value
- Red light = water resistivity is below the threshold value
