Ask A Question

Description & Features

The DHM Series WEBTEC Digital Hydraulic Multimeter is a portable, battery-powered instrument designed for simultaneous measurement of flow, pressure, and temperature in hydraulic systems. The DHM08-S handles flow rates from 20 to 800 L/min (5 to 210 US gpm) and pressures up to 480 bar (7,000 psi), with a fluid temperature range of 32 to 250°F and ambient operating tolerance from -10 to 50°C.

Accuracy is tight across all three parameters: ±1% of reading across 15 to 100% of the flow range, ±0.5% full scale for pressure, and ±1°C for temperature. Porting is via a 1-7/8"-12UN #24 SAE ORB connection, and the unit is compatible with mineral oils to ISO 11158. Constructed from powder-coated mild steel and high-tensile aluminium with FKM seals, it carries an IP54 rating for dust and splash resistance. A 9V alkaline battery powers the unit for approximately 15 hours of continuous use.

Question by: Ross S on May 31, 2026, 9:27 PM
How do I know if the DHM08-S hydraulic multimeter will fit my system's connections?
Answer by: Customer Support on Jun 2, 2026, 3:34 PM
The DHM08-S uses a 1-7/8” -12UN #24 SAE ORB porting, which is a standard fitting size for many hydraulic systems. Make sure your system uses the same fitting to ensure compatibility.
