What is the HFW-50KN?

A wireless-transmission digital push-pull force gauge with an external load cell and hand-held display. The 50 kN range covers push-pull, plug and withdrawal testing on hardware, fasteners, auto parts, wiring terminals and light industrial assemblies.

Which standards apply?

Force indication is referenced to ISO 7500-1 for uniaxial force verification and ASTM E4 practice, with routine calibration to JJG 455, the Chinese verification regulation for working force gauges. Accuracy is ±1% of reading from 10% to 100% of full scale.

What resolution does it give?

Load division is 0.01 kN on a 6-digit display, with N, kg and lb units switchable and gravity acceleration set for the site of use.

How are readings captured?

Five test modes and three display methods, peak value hold, automatic peak capture from 1 to 999 s, max/min comparison with buzzer alarm, and 447 stored values sent to a PC over RS232.

How long does it run?

A 7.2 V NiMH pack charges in 4–6 hours and runs about 15 hours. The charger accepts 100–240 V, and the gauge shuts down after 10 idle minutes.
