Multigas Detector Calibration

Our professional "4-gas" calibration service ensures your 4-gas detector performs accurately and reliably. 4-gas detector models include (FD-4S, FD-4A, FD-600, FD-60, FD-600M). This essential maintenance is recommended every 12 months to compensate for natural gas sensor degradation. When you send your device to our facility, our experienced gas detector technicians will conduct a thorough inspection and diagnostic testing. We begin by measuring and recording the pre-calibration accuracy to document the current performance level. The device is then calibrated using NIST reference gas (or an equivalent NIST gas surrogate for some exotic gases), followed by post-calibration verification to ensure optimal performance. You'll receive a detailed calibration certificate documenting both before and after measurements, officially stamped, signed, and dated by our technician. If any repairs are needed, such as replacement sensors, filters, pump, or battery, we'll provide a quote for your appro
