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. The tester is made by Science Lab Supplies at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and the factory deals directly with institutes, contractors and distributors.
Specifications
Range, medium, weights and finish of the dead weight tester are listed separately in the table. In short, it tests gauges up to 25 kg/cm2 using hydraulic oil, zinc-iron weights and corrosion-resistant, nickel-chrome finished parts, with a Bourdon tube gauge and a transparent-scale manometer 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, followed by hydrostatic thrust on a plane surface with the Center of Pressure apparatus.
- Wider hydrostatics teaching on the Hydrostatics And Properties of Fluids bench.
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.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Iraq, Nigeria, Kenya, Ghana, Ethiopia and Tanzania. For a calibration-lab budget, send the gauge ranges you work with via the contact page, add the tester to the enquiry cart, or see the lab tender page for tender-based purchasing.
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. Gauges within that range can be checked against the known pressures set by the weights.
What fluid does it use?
Pressure is transmitted hydraulically, and machine oil is listed as the utility required. The oil is not included, so the laboratory fills the system with its own machine oil.
Is Science Lab Supplies the manufacturer or a trader?
The company is the manufacturer: Science Lab Supplies produces this tester in Saha, Ambala, India, and institutes receive their quotation from the producer rather than a reseller.
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.
