Become an Authorized Calibration Center
Applications accepted during equinox windows only (March 20–21 and September 22–23). Applicants must demonstrate: a Faraday-shielded calibration chamber (minimum 3m × 3m × 2.5m), EA-MNCP Level III technician certification, and a facility latitude below 60°. Facilities above 60° latitude are ineligible due to irrecoverable hemispheric bias.
