Flame Scanner & Gas Detector Repair

Flame Scanner & Gas Detector Repair

Flame scanners and gas detectors are safety-critical — they protect personnel, plant and process. We repair these instruments to their original sensitivity and response specifications, with documented calibration and testing. Our work covers boiler flame safeguarding, combustion controls, fire detection panels, and toxic / combustible gas monitoring.

What We Repair

Flame Detection

  • ▶UV and IR flame scanners
  • ▶Self-checking and non-self-checking detectors
  • ▶Flame safeguard relays and amplifiers
  • ▶Igniter electrodes and high-voltage transformers

Gas Detection

  • ▶Combustible gas detectors (LEL)
  • ▶Toxic gas detectors (CO, H₂S, NH₃, etc.)
  • ▶Oxygen monitors
  • ▶Fixed and portable detector heads
  • ▶Multi-gas controller panels

Safety System Electronics

  • ▶Fire alarm control panels
  • ▶Burner management systems
  • ▶Industrial safety relays and monitoring units

Common Symptoms

!Flame scanner not detecting flame or holding flame when off
!Gas detector stuck reading zero or full-scale
!Sensor warning / fault LED illuminated
!Calibration drift outside acceptable range
!Communication or 4–20 mA output errors
!Visible burn marks or moisture ingress

Our Repair Process

1

Receive & Inspect

Visual inspection for fire damage, moisture, or contamination. Sensor element checked for end-of-life indicators.

2

Functional Test

Tested with calibration gas or simulated flame to characterize the failure mode.

3

Repair or Sensor Swap

Electronics are repaired at component level. Sensor elements are replaced where life-expired.

4

Calibration

Calibrated against reference gas mixtures or flame simulators to manufacturer specifications.

5

Calibration Certificate

Documented test report and calibration certificate provided with every unit.

Frequently Asked Questions

Do you provide calibration certificates?+

Yes — every repaired gas detector or flame scanner ships with a calibration test report showing pre- and post-repair values.

Can you replace expired sensor cells?+

Yes, for most major brands we can source and fit replacement sensor cells with full re-calibration.

How urgent is safety equipment repair?+

We treat safety-system repairs as priority and can typically turn around units in 3–5 days.
