Answer

All EG30xx and EG4xxx eGauge meters are calibrated during production, ensuring they meet a consistent standard. Once calibrated, these meters do not require any further inspections, maintenance, or recalibration.

While each meter is calibrated to the same standard, an optional calibration certificate is available for purchase at the time of sale. This certificate cannot be issued after purchase. For an example of the calibration certificate, please refer to this article.
