FAQ's
How often should I calibrate my flue gas analyser?
We recommend annual calibration to maintain accuracy, though frequency may vary based on usage and manufacturer guidelines. Contact us for advice specific to your Testo model.
What’s the difference between domestic and commercial analyser calibration?
Domestic analysers (e.g., Testo 310) are designed for home heating systems, while commercial models (e.g., Testo 300LL) handle larger-scale industrial applications, requiring more complex servicing.
Why is a calibration certificate important?
A certificate proves your analyser meets safety and performance standards, essential for compliance with UK regulations and workplace audits.
