Specificity Results
Evaluator claims sensors will respond to any liquid.
Manufacturer's Specifications
Temperature range: -13°F to 158°F (-25°C to 70°C).
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.
