Additel 681 Digital Pressure Calibrator

Features

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, submerible in 1 meter of water.

Application :

  • Precision pressure measurement
  • Field gauge calibration
  • Pressure safety valve (PSV) testing
  • Pressure regulator testing
