Proven Benchtop Pressure Source, 6 Models

Benchtop Pressure Source

A benchtop pressure source keeps the pump on the bench and the instrument in a fixed test line — the setup a calibration lab repeats every day. The YHTC benchtop pressure source range covers six manual units: hydraulic, air and high-pressure configurations from light vacuum steps up to 250 MPa.

Fixed geometry, repeatable mounting and a stable base are what separate a bench unit from a handheld one — and they show up directly in the repeatability of your data. Each model below links to its full specification page.

The Benchtop Pressure Source Range at a Glance

Six cards, five models — the TC168B appears in two ranges:

TC166T — manual air pressure source for -0.095~6 MPa: pneumatic checks with a vacuum dip.
TC168A — manual high-pressure hydraulic power source for 1~160 MPa.
TC168H — manual high-pressure source for 0~250 MPa, the ceiling of the manual lineup.
TC168B — manual hydraulic power source, in 0~60 MPa and 0~100 MPa versions.
TC168T — manual pressure source for 0.085~60 MPa.

Benchtop vs Handheld: How to Choose

Both are manual; the difference is where the rig lives.

Choose benchtop when the same instruments are calibrated repeatedly — the test line stays assembled and every run starts from the same geometry.
Choose handheld when the instrument under test moves: field, commissioning, OEM lines. Our handheld pressure sources cover the portable side.
Choose automatic when volume is the problem — the fully automatic pressure calibration series covers single-operator systems.

A common lab layout keeps one benchtop pressure source per medium — hydraulic, air, high-pressure — and one handheld unit for the work that cannot come to the bench.

Typical Applications

Where a benchtop pressure source earns its footprint:

Calibration labs running daily checks on transmitters, transducers and gauges at constant range.
OEM production lines verifying hydraulic and pneumatic components before shipment.
High-pressure verification up to 250 MPa, where the TC168H replaces a test rig.
Teaching and training, where a stable, repeatable manual bench shows the process clearly.

Benchtop units also make the data better: with the pump, the instrument and the reference gauge all on one stable frame, the readings you log are the readings the system actually produced — no transport, no re-seating, no re-zeroing.

For the reference side, NIST’s overview of pressure and vacuum calibrations explains how bench readings stay traceable to national standards.

Quality and Support

Every benchtop pressure source is manufactured by YHTC, an ISO 9001-certified pressure calibration equipment maker in Beijing. Before packing, each unit is cycled through its working range, and every machine ships with a 12-month warranty.

Quick Questions

Is 250 MPa really manual?
The TC168H uses a mechanical advantage design — a small wheel, a long lever and a geared stage — so one operator can reach the top of the range. Sustained duty at the top end is where automatic systems take over.

Can the air bench do vacuum?
The TC166T starts below atmospheric, at -0.095 MPa, which covers the negative steps most pneumatic instruments need.
