Light Meter Calibration Services
OSHA minimums, USP inspection stations, film and grow operations — lux and foot-candles are compliance numbers.
ACS Calibration delivers NIST-traceable, audit-ready light meter calibration, available at the ACS central lab or directly on-site at facilities across the Southeast.
Illumination Is Regulated More Than You Think
Light meters back real requirements: workplace illumination minimums, inspection-station light levels in manufacturing and pharma, egress lighting checks, photography and horticulture applications. Photodiode sensors and their filters age with exposure — the very thing they measure degrades them — and a meter reading 15% low passes dim workstations all day.
We verify light meters NIST-traceable across the working range with as-found and as-left illuminance data documented — lux and foot-candle scales alike — so lighting surveys and inspection-station checks stand on calibrated ground.
Facility and EHS toolkits calibrate best as a set: IR thermometers, multimeters, and tachometers in one shipment, one due date.
What You Get With Every Calibration
- NIST-traceable calibration certificate with real measurement data — not just a pass/fail sticker
- As-found and as-left readings, so drift is documented
- ISO/IEC 17025 accredited certificate with reported uncertainty — on request
- Calibration label with due date, plus a reminder before your next calibration is due
