Bourdon Gauge
Product Code : LSK-POM-11203
Bourdon Gauge (SKU LSK-POM-11203) is a circular demonstration pressure gauge with a transparent back, a dual 0–50 lb/in² and 0–3.5 kg/cm² dial and a heavy cast-metal base, used to read actual gas pressure and to show how a Bourdon gauge works. It suits school, college and diploma physics labs. Science Lab Supplies turns out the gauge assembly at its Plot 448 factory in the HSIIDC Industrial Area, Saha, Ambala, India, and sells it as manufacturer to schools, colleges, tender contractors and distributors.
Specifications
The demonstration Bourdon gauge is specified row by row below. In short, a circular gauge with a transparent back and a thick black pointer on a white dial reads 0–50 lb/in² and 0–3.5 kg/cm², connects through a ribbed side tubule and rubber tubing, and stands on a heavy cast-metal base.

Applications and Experiments for the Bourdon Gauge
Students connect the side tubule to a vessel or pump with rubber tubing and read the pressure on either scale, while watching through the transparent back as the curved Bourdon tube straightens and moves the pointer. It is clear, readable school physics lab equipment in India for pressure lessons.
- Class 11 gas-law work: measuring gas pressure, as in the Boyles Law Apparatus, Advanced with Oil, which is also read on a Bourdon gauge.
- Converting readings between lb/in², kg/cm² and pascals using the dual scale.
- Applying pressure with a Hand Vacuum Pump, which can produce positive gauge pressures up to 2 atm.
- Diploma courses: explaining the mechanism before calibration work on a Dead Weight Pressure Gauge Tester.
Stay below the 3.5 kg/cm² full-scale reading, and release the pressure before disconnecting the tubing.
Standard Scope of Supply
The gauge is supplied as one assembly: the circular dual-scale gauge with transparent back, thick black pointer and ribbed side tubule, mounted on its heavy cast-metal base. Rubber tubing and any pump or vessel are not included and can be quoted with it.

Frequently Asked Questions
What scales does the Bourdon Gauge show?
The white dial carries a dual scale reading 0 to 50 lb/in² and 0 to 3.5 kg/cm², with a thick black pointer that keeps the reading easy to see during a demonstration.
Does it read gauge pressure or actual pressure?
It is specified to read actual gas pressure rather than gauge pressure, so the scale gives the pressure of the gas directly without adding the atmospheric pressure to the reading.
Why does the case have a transparent back?
The transparent back lets students watch the gauge mechanism move as the pressure changes, which makes the working principle of the Bourdon tube visible instead of hidden inside a closed case.
Where is the Bourdon Gauge made?
Science Lab Supplies makes the assembly at its works in Saha, Ambala, India. Enquiries are handled by the manufacturer directly, so the base, scales and packing are confirmed without going through a trader.
