Frequently Asked Questions – Fixed Gas Detector Calibration Inspection in Malaysia

Fixed Gas Detector Calibration Inspection in Malaysia ensures that permanently installed gas detection systems accurately measure hazardous gases such as combustible gases, oxygen depletion, and toxic gases like CO, H₂S, NH₃, and SO₂. It is essential to meet DOSH (Department of Occupational Safety and Health Malaysia) compliance, maintain workplace safety, and prevent costly production disruptions.

At CT Precise Engineering, we provide calibration inspection services in Malaysia for brands including:

  • RAE Systems (MeshGuard, AreaRAE)

  • Dräger (Polytron series)

  • MSA (PrimaX, Ultima series)

  • Honeywell Analytics (Sensepoint, XNX)

  • Industrial Scientific (Radius BZ1, Ventis Pro)
    We cover industrial sectors from oil and gas to manufacturing, both onshore and offshore across Malaysia.

n Malaysia, most manufacturers and safety regulations recommend calibration every 6 months, but high-risk sites such as refineries, chemical plants, and offshore facilities may require quarterly calibration to ensure compliance with DOSH safety standards.

  • System Inspection – Checking sensor housing, wiring, and positioning.

  • Zero Calibration – Establishing a clean air baseline.

  • Bump Test – Applying a known gas concentration to check response.

  • Span Calibration – Adjusting readings to match calibration gas standards.

  • Functional Test – Confirming alarms, relays, and control panel integration.

  • Certification – Issuing DOSH-compliant calibration certificates recognised across Malaysia.

Yes. We provide on-site calibration services throughout Malaysia, including Klang Valley, Johor, Penang, Kuantan, Sabah, and Sarawak, as well as offshore oil and gas platforms. This minimises downtime and ensures immediate compliance.

Failure to calibrate can lead to undetected leaks, false alarms, and non-compliance with DOSH Malaysia safety laws. This could result in legal action, fines, or operational shutdowns during inspections.

We offer rapid mobilisation within 24–48 hours for urgent jobs anywhere in Malaysia, with ready-to-use calibration gases and certified tools for immediate service.
