Can a gas detector be calibrated in the field?
A. Brasch gas detectors are shipped to the customer fully calibrated. An existing sensor cannot be calibrated in the field because conditions that affect the calibration cannot be controlled. An otherwise functional detector requiring recalibration can be restored to “like new” condition by replacing the electronic board containing the sensor with a new, calibrated sensor board assembly. This assembly is shipped to the customer properly calibrated. Once installed, the detector can be considered accurate within design parameters.
