Cartoli Instruments carries Wohler equipment used for inspection and combustion performance verification. Wohler endoscopes and inspection systems support remote visual inspection of ducts, flues, boilers, and hard-to-reach cavities, helping technicians document corrosion, blockages, and installation defects. For heating service, Wohler gas analyzers and combustion analyzers measure key parameters such as O2, CO, CO2, draft, and efficiency values to support safe burner tuning and compliance checks. These tools are common in HVAC service, facility maintenance, and commissioning work where clear documentation matters. Cartoli is an official distributor of Wohler models, accessory kits, replacement parts, and configuration help comparing probe types, sensor options, and reporting features for specific job requirements. Many platforms support on-device reports, SD/USB export, and rugged cases, and can be paired with cleaning tools to verify results before and after service. Quotes are available for multi-technician teams.
