The Michell Instruments Sensor Exchange Program allows a replacement sensor to be ordered before recalibration is due. The replacement is typically shipped within 1-2 weeks. Upon receipt, the replacement is simply swapped with the installed sensor needing recalibration. The old sensor is then returned to Instrumart within 30 business days and recycled into the Sensor Exchange program.
When the old sensor is received at the factory, the protective cap and sensor tile are removed. The sensor body is ultrasonically cleaned to prevent any possibility of cross-contamination, and the performance of the digital electronics is thoroughly verified. A new sensor tile is then mounted and the sensor is recalibrated, making the unit ready to be used for the next Sensor Exchange order.
A Sensor Exchange sensor is calibrated using the same procedure and instrumentation as a new sensor, and a calibration certificate traceable to NIST is supplied. The program also provides the same calibration warranty statement as a new sensor.
