Exhaust Gas Calori meter (Product Code: SLE/EE/03) is a gas-to-water heat exchanger used to measure the heat carried away in engine exhaust gases during IC engine tests in engineering laboratories. Exhaust flows through its multi-tube bundle inside a cooling-water jacket, and thermocouples with a four-channel digital display give the temperatures and flow needed for an engine heat balance. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM and technical educational equipment manufacturer, at its own factory in Ambala, India.

In an engine heat-balance experiment, the energy in the fuel is divided between brake power, heat to the engine cooling water, heat carried out in the exhaust and other losses. This calorimeter quantifies the exhaust share: the heat picked up by the cooling water equals its mass flow rate multiplied by its specific heat and temperature rise, while the fall in gas temperature across the exchanger shows how much exhaust energy was recovered.
Establish a steady cooling-water flow with the console valve before the engine is started, and never pass exhaust through the exchanger without water – the pressure-relief valve is a safeguard, not a control. Take readings once all four channels have settled. For colleges setting up a calorimeter lab in India around a single engine test set, this unit adds the thermal measurement that completes the practical.
This calorimeter is an original product of ScienceLab, the trading name of Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597). As the OEM, the company manufactures it at its licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala (Factory Licence AMB-ONLINE-CHD-J-414).
Engineering colleges, polytechnics, dealers and importers buy it factory-direct, and requests for replacement thermocouples, valves or display units go to the same manufacturer – ask us about availability. The company profile gives more background.

How does the Exhaust Gas Calori meter measure exhaust heat?
The Exhaust Gas Calori meter passes engine exhaust through tubes surrounded by a jacket of flowing cooling water. Heat content is assessed from the cooling-water flow rate, measured by a turbine flow meter, and the water and gas temperatures recorded by thermocouples at inlet and outlet.
What instrumentation comes with the Exhaust Gas Calori meter?
The Exhaust Gas Calori meter includes thermocouples at the gas and water inlets and outlets, a turbine flow meter and a digital four-channel temperature and flow display unit. The display mounts on the instrumentation rail of the test set console frame for easy monitoring.
Is the Exhaust Gas Calori meter protected if cooling water fails?
Yes, the Exhaust Gas Calori meter has a pressure-relief valve in case insufficient cooling water is flowing. Students should still set and check the water flow with the hand-operated console valve before running the engine, because the relief valve is a safeguard rather than a substitute.
Which engines can be tested with the Exhaust Gas Calori meter?
The Exhaust Gas Calori meter analyses exhaust gases from the test engine mounted on the test set, so it is used with engines that set accepts, such as a four-stroke petrol or diesel engine. Share your engine details with us to confirm the connection arrangement.
Who manufactures the Exhaust Gas Calori meter?
The Exhaust Gas Calori meter is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its licensed factory in Saha, Ambala, Haryana, India. Institutions and dealers buy it factory-direct, and repeat orders or spare-part requests go straight to the manufacturer.
Can a calibration certificate be supplied with the Exhaust Gas Calori meter?
Calibration certificate availability for the thermocouples and flow meter of the Exhaust Gas Calori meter should be discussed with us before ordering. Mention the requirement in your enquiry so the quotation states exactly what documentation will accompany the unit.
What information do you need to quote the Exhaust Gas Calori meter?
To quote the Exhaust Gas Calori meter we need the quantity, the engine test set and engines it will serve, companion items such as a fuel gauge, and the delivery destination. Quotations are prepared for institutions in India and international markets.
For a quotation on the Exhaust Gas Calori meter, write to us via the contact page or place it in the enquiry cart. You deal directly with the manufacturer, whether the unit is for one laboratory or a multi-campus order.
