About Us

J. N. THERMOCONTROLS was established in 1994 at Mumbai, India with the prime objective of manufacturing / marketing of preliminary process instrumentation, specifically Pressure Gauges & Thermometers for Indian Market.

As J. N. THERMOCONTROLS developed, it rapidly acquired a reputation for high quality instrumentation and has built a solid customer base by providing its client with technical knowledge and expertise.

During 1998 J. N. THERMOCONTROLS began to broaden its market base by exporting its product and also included RTD's, Thermocouples and Pressure Gauge Testers to the product range. In the year 2001 Temperature Calibrator and Digital Temperature Indicator/Controllers/Scanners were introduced.. In the year 2002 Sight Flow Indicators, Level Indicators were added to the product range. In the year 2003 Flame Arresters were included to the product range. And in the year 2007 Temperature transmitters and Data loggers were included in the product range.

More so we at J. N. Thermocontrols have established full test & callibration facilities tracable to national standards for most of the above mentioned products to ensure the best and seemless quality. We are also an ISO 9001:2000 organisation accredited by UKAS.

J. N. THERMOCONTROLS is catering various industries like Petrochemical, Chemicals, Pulp and Paper, Plumbing, Power Generation, Food Processing, Refrigeration, Hydraulics, Bulk Drug & Pharmaceuticals and many others where stringent quality standards are maintained.
