Rugged construction, urethane over molding protects against shock if a module is accidentally dropped and also seals against dirt, dust, and moisture Convenient setup, one-meter cable between the pressure module and calibrator reduces the length of connecting tubing to the pressure source Temperature compensated from 0 °C to 50 °C (32 °F to 122 °F) Fully interchangeable because all measurements are completed in the pressure module itself and then communicated to the calibrator in digitized form Each module has its own serial number to maintain independent traceability
