With advanced microprocessor technology and state-of-the-art silicon pressure sensors, the 681 series digital
pressure gauges provide an accurate, reliable, and economic solution for a wide range of pressure applications.
They are loaded with functionality and remarkably easy to use. To reach the best performance, every silicon
pressure sensor in our gauges is specially aged, tested and screened before assembly. At Additel, fully temperature
compensated accuracy means every sensor is pressure tested at several environmental temperatures from
-10°C to 50°C. With this test data individual coefficients are generated and stored in the gauge characterizing its
performance over the full temperature compensated range. And now the ADT681IS comes with an IP67 rating
meaning it is dust resistant and water proof, submersible in 1 meter of water.
