General Specifications*

Standard range is -40°F to 176°F, -40°C to 80°C with optional stainless steel mounting bolts which maybe required for temperatures below -20°F, -29°C.

Accuracy depends upon proper gauge sizing and is typically ±5% of dial indication. Accurancy may be less due to variations in liquid temperature. Accuracy may be less for some tank shapes and sizes. Accuracy may be less near full and empty. Accuracy may be less if tank is not level. This gauge is not to be used for filling. All accuracy estimates are expressed as a percent of full scale.

Shock & Vibration
Suitable for mobile service applications.

Maximum Pressure
375 psig [25,8 Bar]

UL Listing
