The Resilite QC Light is a positive, reliable and economical method of monitoring water quality via its electrical conductance.
Bright Red-Green visual output is easy to read.
The monitoring is simple:
The green light indicates the water conductivity is below the value (pure), the red light warns that it is above the value (not pure). Uses a wall transformer to convert 100v to 9v to insure safe operation and longer life. 220v Eurpoean is no longer available.
Available in 2 Meg ohm, 1 Meg ohm, 500k, 200k, 50k, 20k, 10k, and 5k.
Note : QC lights are not a very accurate way of measuring water quality, they are an "indicator" of quality. For accurate measurement and display of water quality a meter must be used.
