Verify Verification Gases
Preparation is key in insulating gas analysis. Ensuring the analyser is within calibration is fundamental to safe operation, compliant measurement and accurate testing. EMT Verify precision gas verification products set the industry benchmark in quality and stability for proving your insulating gas analysis results.
EMT NIST traceable gas verification products utilised during operation provide continued assurance that the analyser is performing as it should be, that the measurements shown are accurate, and that these are in line with the measurement values and tolerances of the supplied gas.

We believe analysers should be kept in peak performance at all times. EMT therefore recommend that calibration and verification against measurement standards should continue between maintenance schedules, certifying equipment prior to use and at specified intervals.
EMT Verify gases provide user performance verification and in-field calibration in under 5 minutes; enabling maintenance teams to undertake these procedures on site, reducing equipment downtime.
Verify gases can be used for:
- Any gas analyser to ensure function within specification
- Pre-testing to ensure accuracy
- On-site in-field user calibration where analyser sensors may have drifted
- Post-testing to ensure accuracy remains consistent
- In between maintenance schedules and annual servicing
