*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.

Manufacturer's Specifications:
Temperature range: -13 to 158F (-25 to 70C).
Interstitial liquid level should be adjusted to center of sensor.

Comments:
Primary use is interstitial or annular space of a double-walled tank partially filled with brine solution.
Activates alarm if solution level exceeds upper or lower limits.
