Precision Force Measurement

The Jonard GD-30 Dyno Gauge is an analog instrument built for technicians who need to verify spring tension, contact pressure or small-component actuation forces. It covers a 40 g to 350 g range with a stated accuracy of ±10 g and a graduation of 1 g, making it suited for bench inspection and assembly-line checks where digital logging is not required.

Analog Operation Characteristics

Because the gauge uses a purely mechanical display, it draws no power during measurement and produces no fan or coil noise. The supplier notes an auto power-off function and a charger with USB cable, which apply only to the secondary digital display screen; the primary analog needle remains passive. No thermal output or acoustic signature is generated in normal use.

Included Adapters and Certification

Six force adapters are supplied to fit different contact geometries, expanding the range of test points without extra purchases. A calibration certificate ships with each unit, providing traceability for quality-system records. The 90-day manufacturer warranty covers defects but does not extend calibration validity beyond the initial certificate.

Questions about this item

How do I install the GD-30 and which step is often missed?

Select one of the six force adapters, attach it to the gauge, then zero the analog needle before applying any load; skipping the zero step shifts every reading by up to ±10 g.

What maintenance or replacement will the GD-30 need later?

Recalibrate using the supplied certificate whenever readings drift beyond ±10 g; the 90-day manufacturer warranty covers the initial period, after which recalibration is the owner's responsibility.

What limit appears first during sustained use of the GD-30?

The analog display graduates in 1 g steps up to 350 g maximum force, so resolution becomes the limiting factor before the 350 g range is reached.
