Gauges should be calibrated every 2 years. You can see more details on our Calibration Page.
Some customers like to do a FIELD CHECK to check gauges in the field against a recently calibrated gauge. We have created a simple Excel-based tool which supports the Field Check Process and Summary of Results. Download FIELD CHECK EXCEL TOOL here.
We recommend that a field calibration check be performed annually, or whenever a gauge has been dropped or damage is suspected. Results of field calibration checks should be recorded and documented by the customer using the sample log sheets provided at the end of the calibration check document. Gauges that fail the Digital Gauge Field Calibration Check will need to be sent to TEC Minneapolis for re-calibration
