Digital Manifolds Manufacturer,Supplier and Exporter in India
Product Code : EL-RACLE-12747
Jlab Export is a leading Digital Manifolds Manufacturer,and suppliers in India
A digital manifold replaces needle gauges with pressure sensors and a 4.3-inch colour touch screen. This one reads high-side and low-side pressure and temperature and shows vapour and liquid saturation temperatures. It works out superheat and subcooling for any of its 126 stored refrigerant profiles. It comes with a vacuum sensor, two temperature clamps, four hoses and a backpack carrying case.

Lab Exercises with the Digital Manifold
Students connect the 3/8 in yellow vacuum hose to one of the Fast Vacuum Pumps and pull the system down. The vacuum sensor tracks the depth of vacuum as the pressure falls. They set a vacuum target, close off the pump and use the pressure hold mode to watch the rate of rise. A steady rise points to a leak or to moisture still boiling off.
On the Air Conditioning Test Rig, the two clamps go on the suction and liquid lines. Students select the refrigerant profile, read superheat and subcooling straight from the screen and log a run for export over USB. The manifold can also show humidity, dry bulb, wet bulb and dew point measured wirelessly, which fits the rig study of humidification and dehumidification.
For a strength test, the circuit is pressurised from the Nitrogen Pressure Test Kit and the pressure hold mode shows any rate of fall.
Frequently Asked Questions
What can a digital manifold do that needle gauges cannot?
It reads pressure and pipe temperature together and calculates superheat and subcooling for the selected refrigerant, so no chart is needed. It also logs data, holds a pressure reading to show its rate of change, and measures vacuum with its own sensor.
Which refrigerants can it read?
It stores 126 refrigerant profiles. Pick the one on the system rating plate before reading saturation temperatures, superheat or subcooling. The pressure reading is the same whatever profile is chosen, but every temperature it works out depends on that choice.
How are superheat and subcooling measured?
Fit one temperature clamp on the suction line near the service valve and the other on the liquid line. The manifold compares each clamp reading with the saturation temperature for the matching pressure and shows superheat and subcooling on screen.
What pressure can it take?
The maximum working pressure is 700 psia (48.3 bar), so nitrogen test pressures must stay below that. Readings can be shown in bar, psia, psig, kPa, MPa or kg/cm2, whichever the course or the job sheet uses.
How is the data saved and shared?
Readings are logged in the instrument and can be exported to a computer over USB or sent by Bluetooth. Phone and PC apps come on a CD or flash drive. The battery is recharged through the USB port, and its level shows on screen.
