Technical Specifications

Measurement Specifications

Water Depth

Range: 0 - 10,000 mm

Resolution: 1 mm

Accuracy: ±0.25% of full scale at 20 °C

NOTE: Depth measurement accuracy assumes no abrupt temperature variations.

Temperature

Range: -40 to +60 °C

Resolution: 0.10 °C

Accuracy: ±1.00 °C

NOTE: The pressure transducer may be damaged or destroyed if frozen in ice. Remove the sensor if the water temperature could drop below 0°C (32 °F).
