Dead Weight Pressure Gauge Tester
Product Code : LSK-TOMLE-10625
Dead Weight Pressure Gauge Tester (SKU LSK-TOMLE-10625), also called a dead weight tester, checks and calibrates pressure gauges up to 25 kg/cm2 by generating a known hydraulic pressure from calibrated weights on a piston. Engineering, polytechnic and instrumentation students use it to learn gauge calibration. Science Lab Supplies makes the tester in its own factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and offers it straight to institutes, contractors and distributors.
Specifications
The tester uses hydraulic oil as the medium for transmitting pressure and has a set of zinc-iron weights for long use. Parts are made from corrosion-resistant material with nickel-chrome finish against rust, and the components, including a Bourdon tube pressure gauge, are arranged on a base plate.

Applications and Experiments for the Dead Weight Pressure Gauge Tester
The tester is used to calibrate a Bourdon tube gauge: known weights are loaded, the gauge reading is recorded at each step up to 25 kg/cm2, and the error is plotted against true pressure for loading and unloading. It is standard equipment for instrumentation and measurement practicals.
- B.Tech/B.E. mechanical and instrumentation: calibration of pressure gauges.
- Diploma and ITI Instrument Mechanic trade: gauge error, hysteresis and zero checks.
- Fluid mechanics labs: pressure as force per unit area on a piston.
- Vocational training equipment for TVET measurement and maintenance modules.
The system holds oil under pressure. Load weights gently, check fittings before pressurising, and release pressure before removing a gauge.
Standard Scope of Supply
Each tester comprises the hydraulic pressure system on its base plate, the set of zinc-iron weights, a Bourdon tube pressure gauge and the manometer with transparent scale. Not included: the machine oil used as the pressure medium, which the laboratory provides.
Packing, MOQ and Lead Time
Quotations are available for a single tester or several for a measurement lab, and each states packing, delivery time and price for that quantity. Ask this TVET lab equipment supplier to add gauges or other instruments to the same quotation.

Frequently Asked Questions
What pressure range does the Dead Weight Pressure Gauge Tester cover?
It is built to test pressure gauges up to 25 kg/cm2, which is about 24.5 bar or 2.45 MPa.
What fluid does it use?
Pressure is transmitted hydraulically, and machine oil is listed as the utility required. The oil is not included.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies manufactures this tester itself in Saha, Ambala, India, so each quotation is issued by the maker.
How does a dead weight tester give a known pressure?
Weights of known mass act on a piston of known area. The pressure in the oil equals that force divided by the area, so the gauge under test can be compared with a true value.
Related Measurement Equipment
Calibration is part of a wider measurement lab. These four instruments pair with the tester: a Bourdon gauge for teaching how gauges work, and three dynamometers that measure cutting forces, all quotable together for an instrumentation or production engineering lab.
