Additel’s 681 Pressure Gauges are equipped with advanced microprocessor technology, and specially aged, tested, and screened silicon pressure sensors that guarantee you’ll get the best performance. Every sensor is pressure tested in environmental temperatures from -10°C to 50°C. Individual coefficients are generated from this test data and are stored in the gauge, characterizing its performance over the full temperature compensated range.
