Why Source from Flame India

Manufacturer, not a trader

Flame India manufactures all thermocouples, RTDs, and pressure gauges at its Kolkata facility, giving buyers direct factory pricing and production control.

ISO 9001:2015 certified production

Manufacturing processes are certified to ISO 9001:2015, with products built to EN-837 (pressure gauges) and IEC 60751:2022 (RTDs), supporting documentation requirements for regulated industries.

IBR certification for pressure applications

IBR certification covers instrumentation intended for Indian Boiler Regulation-governed installations, a requirement in power and process plant procurement.

Wide specification coverage

A single vendor covers Type J/K/T/E/N thermocouples, Pt100/Pt1000 RTDs across three construction types, and four pressure gauge variants, reducing the number of suppliers needed for a plant instrumentation package.

IP66-rated enclosures as standard

All pressure gauge models are rated IP66, suitable for outdoor and wash-down environments common in cement, steel, and petrochemical plants.

20 years of industrial supply

Operating since 2005, Flame India has supplied instrumentation to heavy industries across India and export markets in the Middle East and Africa.
