Multiple gauges, multiple ranges: more equipment to carry, manage and select during testing.

Inconsistent readings: analogue gauge drift can make accurate fault finding more difficult.

Pressure changes are harder to follow: digital readings make changing pressure easier to monitor during testing.

Downtime adds up: slower diagnostics, repeat testing and return visits can keep equipment out of service longer.

DM80 M UMS service kit · 0–700 bar

The high tier: 4 buttons + USB data logging (8 GB, CSV export). Kit carries the 2 m hose, direct adaptor, test couplings, reduction adaptors and CNC-milled foam-inlay case: the fittings a hydraulic service tech carries as standard. 3-point calibration certificate + serial traceability included.

Pump pressure checks

Verify output against spec, watch it live under load.

Relief-valve setting

Adjust with one hand, read the exact cracking pressure with the other.

Cylinder drift & leak-down

Digital resolution shows the slow decay a needle hides.

Hose & system commissioning

USB logging hands the customer a documented test record.

Digital vs analogue pressure gauges

Analogue gauges drift and readings get interpolated. A digital readout gives the exact value: 0.25% BFSL: with no parallax and no guesswork mid-swing.

How many pressure gauges do you actually need?

One. The DM80 covers the spread you currently carry several analogue gauges for: including the 630 bar most hydraulic work actually calls for.

Common hydraulic pressure testing mistakes

Wrong range for the circuit, extra adaptors adding leak points, trusting a drifted needle. The kit removes all three: one gauge, direct hose connection, calibrated readings.

Selecting the right pressure testing kit

Service work: the UMS kit with USB logging. Workshop and general repair: the DM80 M kit. Both ship with every fitting and the calibration certificate.
