Amprobe 2100-BETA 4312508 2 Pole Tester
The Amprobe 2100-BETA 4312508 2 Pole Tester checks voltage, continuity and phase in electrical systems. Its two-pole design supports safe work in commercial and industrial settings. Clear LED and LCD displays help users read results quickly.
Automatic AC and DC detection reduces the need for manual setup. The tester uses LED steps from 12 V to 690 V, while its LCD measures from 6 V to 690 V AC/DC. An audible alert also sounds when the measured voltage reaches 50 V AC or 120 V DC.
Practical Testing Functions
The Amprobe 2100-BETA 4312508 2 Pole Tester includes automatic continuity testing up to 500 kΩ. It also checks single-pole phase and shows full-range polarity. In addition, green LEDs show right or left phase rotation on three-phase systems.
Switchable load buttons apply a test load for RCD checks and help reduce the effect of stray voltage. Users can select a 10 mA or 30 mA RCD trip test. A Data Hold function keeps voltage readings on the display when the probes must be removed.
Built for Site Work
A torch light and backlit screen support work in dim areas. The double-insulated lead includes a wear indicator that shows when the cable needs replacement. IP64 protection also guards the tester against dust and splashing water.
The Amprobe 2100-BETA 4312508 2 Pole Tester meets CAT IV 600 V and CAT III 690 V safety ratings. It is GS approved and built to the listed IEC, EN and DIN standards. Two different set types are available, so buyers can select the option that suits their work and required contents.
