Gas Detector Calibration Services in Dubai & Across the UAE
Toxic gas is invisible — your detector is the only thing standing between your team and it. TCAL calibrates, repairs, rents and overhauls portable and fixed gas detectors from an ISO 17025 accredited laboratory, with collection and delivery across the UAE.
The Gases That Kill Workers Are the Ones They Never See
Every year many workers are injured after exposure to toxic gases and vapours. These accidents happen precisely because the hazard is invisible to the person it affects — there is no warning, no smell in many cases, and no second chance. The only way to avoid them is to monitor the surrounding atmosphere continuously, using gas detectors and environmental monitoring equipment that are known to be working.
That last part is where calibration comes in. Gas Detector Calibration Services in Dubai and across the UAE exist to prove that a detector's sensors still respond correctly to flammable gases, oxygen depletion and toxic gas — as required both by manufacturer standards and local regulations. Gas detector manufacturers typically recommend calibration every six months to verify the integrity of the sensor and the other components of the equipment.
TCAL calibrates, repairs and supplies gas detection equipment from an ISO 17025 accredited laboratory that complies with local regulations. We can provide complete overhauling, repair, rental, calibration and service for all kinds of gas detectors — including replacement of sensors, components and pumps. Being centrally located in Dubai, we offer collection and delivery across the UAE, plus on-site and round-the-clock calibration.
Many clients run gas detection alongside other safety-critical instruments, combining this service with PSV and SRV calibration or managing everything under an annual calibration contract so the six-month cycle never slips.
Single Gas vs Multi Gas Detectors
The two behave very differently under calibration — and knowing which you own tells you what your instrument can and cannot be adjusted to do.
Single Gas Detectors
One hazard, one sensorUsed mainly to detect a single toxic or hazardous gas condition — most commonly H₂S, oxygen depletion, or the presence of combustible gas.
- May not be equipped with a real-time display
- Often cannot be adjusted during calibration, even when exposed to gas of known concentration
- Verification confirms whether the unit still responds — and when it must be replaced
Multi Gas Detectors
Four to five gases at onceEquipped with several sensors — H₂S, CO, O₂, LEL and others — detecting four to five gases simultaneously, usually with an integrated pump.
- Real-time display and alarms as standard
- Can be calibration-adjusted when exposed to gas of known concentration
- Often include a self-calibration option before every use

How We Calibrate Gas Detectors
There is only one honest way to calibrate a gas detector: expose it to real gas of a known concentration and see what it does.
Receive & Inspect
Each unit is logged by make, model and serial. We check sensor condition, pump operation, filters and physical damage — a blocked pump alone can stop gas reaching a healthy sensor.
Expose to Test Gas
The detector is exposed to test gas of known concentration — the only method that proves a sensor still responds correctly to the hazard it is deployed against.
Verify Readings & Alarms
We verify the instrument's real-time readings against the applied concentration and confirm the alarms actually trigger — a correct reading with a dead alarm is still a failed detector.
Adjust, Certify or Repair
Adjustable units are corrected and re-verified. Where sensors, pumps or components have failed, we replace them — then certify the instrument with its next-due date.
Rental, Repair & Overhaul
We provide gas detectors on short-term and long-term rental — and during the rental period, calibration is free of charge. For clients sending their own units in, we supply spare replacement equipment during calibration, so your site is never left unmonitored while its detector is with us.

Gas Detector Calibration — Frequently Asked Questions
Gas detector manufacturers generally recommend calibration every six months, to check the integrity of the sensor and the other components of the equipment. Detectors used in harsh conditions, exposed to contaminants, or deployed on safety-critical confined space work may warrant more frequent verification — and bump testing between calibrations is good practice.
The only way is to expose the detector to test gas of a known concentration, then verify the instrument's real-time readings and confirm its alarms activate correctly. Anything that skips the applied gas is not a calibration. It is also important that calibration is carried out by a laboratory holding the appropriate approvals to do this work.
No — and this catches people out. Multi gas detectors, with their real-time displays and pumps, can normally be calibration-adjusted when exposed to gas of known concentration. Many single gas units cannot: they may have no real-time display and no adjustment capability, so calibration confirms whether they still respond and tells you when to retire them.
Two common reasons. Sensors can be contaminated or degraded by exposure to certain substances, so their response is poor even though the unit powers up normally. And even with a perfectly healthy sensor, a blockage in the pump can stop gas reaching it at all — the detector then reports clean air in an atmosphere that is anything but.
Yes. We provide gas detectors on short-term and long-term rental, and calibration is free of charge throughout the rental period. We also supply spare replacement units to customers while their own equipment is being calibrated, so a site is never left without monitoring.
