External Sensor • High Resolution • ±0.5% Accuracy

Versatile digital force gauges with external high-resolution load cells, ideal for precise tensile and compressive force measurements in workshop, lab or test‑bench setups.

The KERN FH‑EXT gauges combine a compact display with a detachable external sensor, delivering high-resolution and ±0.5 % accuracy across multiple ranges. With peak-hold, track mode, limit setting (visual & acoustic), and internal memory, these gauges are optimised for laboratory testing, quality control, and industrial applications. Powered by rechargeable NiMH batteries and featuring RS‑232 (plus USB on selected models), they offer both portability and integration flexibility.

Key Features

• External Load Cell: Suited for delicate or low-force measurements with sensor-independent mounting.
• Peak / Track and Limit Mode: Capture peaks or continuously monitor forces with threshold alarms.
• Internal Memory & Statistics: Store up to 10 readings and calculate min/max/average values.
• Rechargeable Power: NiMH pack (8.4 V/1200 mAh) with AC adapter included.
• Interfaces: Standard RS‑232; FH 500 EXT adds USB connectivity.
• Portable Display: Rotatable LCD with auto-power off for convenience.
