Dead Weight Vacuum Gauge Tester

This instrument is used for calibration of vacuum gauges and other sensing, transmitting and recording vacuum instrument. The 'PRESTO' Vacuum Gauge Tester is a quick and convenient method of calibration free from the disadvantages of using the fragile mercury manometer.
The main components of the tester are :

SCREW PUMP to generate the vacuum in the tester conveniently and precisely. It is of adequate capacity and is operated by turning the spoked handle. FREE PISTON Assembly of special steel, hardened, tempered ground and lapped to accurate size and very fine surface finish to provide true floating action. The free piston is suspended vertically downward from a rigid frame and is connected by a pipe to the screw pump. A CARRIER weight is attached to the free piston for taking more weights.

VALVE is provided to connect the circuit to the atmosphere and thus check zero of the gauge.
GAUGE CONNECTOR of 1/2" BSP (female) union for connecting gauge to be tested. Other sizes of gauges can be connected by using adaptors.
SET OF WEIGHTS directly marked in convenient values of vacuum and easily stacked on the CARRIER weight. It is available in either / and kgf / cm 2 , mmHg, in Hg units. Storage box is provided.

BASEPLATE of sturdy construction provided with legs and levelling screws.

Q: When do labs usually need a Dead Weight Vacuum Gauge Tester?
A: This need comes up when gauge readings start to feel off. Numbers do not match earlier records. Labs use this tester to compare gauges with known pressure values before using them again for routine checks.

Q: How is a dead weight tester for pressure gauge calibration done?
A: The gauge reading is matched against certified test gauges from the National Physical Laboratory in New Delhi. A test certificate shows both readings side by side. This makes it easy to spot any difference without guesswork.

Q: What standard accessories are supplied with a dead weight pressure gauge tester?
A: The tester comes with a weight storage box, spare seals, a dust cover, and an instruction manual. A tin of oil is included. A basic tool kit is also provided with spanners, an Allen key, a screwdriver, and a spirit level.

Q: Can this tester be used for vacuum as well as pressure checks?
A: Yes. It works for low-pressure ranges and vacuum testing. This suits labs that handle different types of calibration work on the same setup.

Q: What is the Dead Weight Vacuum Gauge Tester price?
A: The price changes with pressure range and configuration. Customers can send an email to info@prestogroup.com. You can also call +91 9210903903. Pricing is shared based on the testing need.

Q: How often should gauges be checked using this tester?
A: Most labs follow fixed schedules. Regular checking helps keep gauge readings steady during daily operations.
