Certification, calibration & package
Catalog: KC battery safety confirmation XU102707-21002A. KC: R-R-WPP-GD4Mini. FCC / CE / RoHS.
Confirm explosion-proof ratings and the scope of certification against model-specific documents before procurement. The marks above do not establish an explosion-proof rating.
The catalog lists a storage case, calibration cap, manual and manufacturer test report. Ask about the terms and availability of separately issued KOLAS calibration/test documentation.
Frequently asked questions
What should I confirm before selecting GD4 Mini?
Provide the target gases, expected concentrations, temperature, humidity, application and required certifications. We compare your conditions with the catalog specifications.
Where can I confirm calibration intervals and manuals?
Request the current model manual and calibration requirements through technical support. Intervals and performance not specified in the catalog need confirmation.
