A bump test is a quick functional check to confirm that a gas detector’s sensors and alarms respond to target gases. Calibration is a precise adjustment using certified, traceable test gases to ensure the readings are accurate. Both are essential—bump tests verify operation, calibration verifies accuracy.

We offer both options. Our mobile service engineers can calibrate and maintain equipment on-site anywhere in the UK, minimising downtime. Alternatively, you can send detectors to our fully equipped service centre, where we typically provide a 3-working-day turnaround.

Yes. Every calibration includes a certificate traceable to national standards, detailing the gases used, test results, and service date. Certificates are issued electronically for easy storage and compliance audits.

If a sensor or component fails, our engineers will identify the cause and provide repair or replacement options using genuine parts. We’ll always obtain your approval before carrying out any additional work, ensuring transparency and cost control.

No. We currently provide servicing and calibration on a one-off or as-needed basis. However, we maintain detailed service records and calibration certificates for all completed work, making it simple for you to track service intervals internally.

Before sending equipment, ensure each detector is clean, clearly labelled, and free from damage or contamination. Remove accessories such as clips or hoses where possible. We’ll inspect the unit upon arrival, confirm the work required, and contact you if any additional repairs are needed.
