Detailed Technical Feature Breakdown

Dual-Range Sensitivity & Frequency Optimization (AC-3 & AC-4)

The AC-3 and AC-4 detectors feature dual sensitivity ranges (AC 12V-1000V high and AC 48-1000V low),optimized for 50Hz/60Hz power systems. This allows technicians to detect hidden low-voltage control wiring as well as standard industrial power circuits.
CAT IV 1000V Safety Protection (AC-II)

Engineered to meet rigorous electrical safety standards, the Vici AC-II carries a CAT IV 1000V rating. This provides maximum protection for technicians working on primary supply cables, utility meters, and outdoor service drops.
LCD Screen & Analog Bar Display (AC-4)

The AC-4 model upgrades traditional pen testers by incorporating an active LCD screen paired with an analog signal strength bar graph and color-changing backlight, giving technicians precise visual feedback on proximity to voltage sources.
Dual-Mode Rotational Speed & Surface Velocity Auditing (DT-6236B)

The DT-6236B tachometer supports both non-contact optical laser sensing (for rotating fan blades and motor shafts) and physical contact measurement (using adapter tips to measure conveyor belt linear speed in meters per minute).
Automated 96-Group Data Logging (DT-6236B)

Equipped with internal memory capable of automatically storing up to 96 groups of measurement data,eliminating the need to manually log tachometer readings during multi-point motor testing.
