*The
"high" and "low" refer to high and low level alarm points of
hydrostatic sensors.
Specificity
Results:
Evaluator
claims sensors will respond to any liquid.
Comments:
Q0003-001
and Q0003-002 sensors must be cleaned with rubbing alcohol, or dish soap and
water after exposure to product.
Sensors
are reusable if not completely saturated with product.
