Keep your Testo 310 or 320B precise, safe and compliant with our Testo 310/320B Flue Gas Analyser Calibration. We deliver fast turnaround, clear pricing and a dependable, UK wide collection and return service. Every analyser gets a health check, a traceable certificate and careful cleaning before dispatch.
Our service follows a proven six step process. Instruments are booked, received and logged. They stabilise in our climate controlled lab. We inspect, test and adjust using UKAS calibrated references. Results are documented, labels updated and packaging prepared for return. If required, we replace the O2 or CO sensor with genuine OEM parts to maintain accuracy.
Fast and Effective
Pricing is simple. Year 1 and 2 cost £119 plus VAT. Year 3 costs £159 plus VAT. Years 4 and 5 return to £119 plus VAT. Units over five years receive a quotation after inspection. Overdue services may attract a late fee of £75 plus VAT. We always seek approval before extra work.
