Resilite 3/4'' NPT RES7046-1MEG, 1 Meg Ohm Water Quality/Resistivity Indicator Light

- The monitoring is simple: the green light indicates the water conductivity is below the threshold value, the red light warns that it is above
- 1 Meg ohm/cm resistivity light
- 3/4" MPT
- Uses a wall transformer to convert 100-240 VAC to 9 VDC to insure safer operating and longer life
- Reliable and economical method of monitoring water quality via conductivity
- LED output and solid state circuitry utilizes a symetrical squarewave sampling voltage to eliminate plating and extend electrodfe life
- The LED output and solid state circuitry will outlast conventional neon lamps by thousands of hours.
