HASEGAWA HSS-25B1 Voltage Detector For Medium/Low Voltage (AC 80V~~25KV)
The HASEGAWA HSS-25B1 is a handheld, non‑contact voltage detector designed for both medium‑ and low‑voltage applications ranging from 80 V to 25 kV AC. Its telescopic insulation rod can be extended or retracted, allowing safe distance measurement of high voltages and close‑range verification of low voltages. The detector combines a lightweight, resin‑based construction with an ergonomic grip and nameplate portion to ensure user comfort and safety during prolonged inspections.
Equipped with both visual and audio indicators, the HSS‑25B1 emits a high‑luminance flashing red LED and an intermittent buzzer, providing unmistakable alerts when voltage is detected. The embedded electronics are safeguarded by a waterproof detecting head and a removable insulation rod that can be taken apart to remove any accumulated moisture, further enhancing operational reliability in varied field conditions.
Power is supplied by two LR44 button‑cell batteries, yielding up to 50 dB of audible warning at 2 m, even under bright ambient light (8,000 lux). The detector’s compact form factor (≈140 g) and telescopic reach make it ideal for maintenance teams working on electrical installations, allowing for quick, non‑intrusive voltage checks without the need for bulky test equipment.
Features:
- Detects high voltage from a safe distance (rod extended) and low voltage at close range (rod contracted).
- Telescopic, compact, and lightweight design.
- Clear electronic buzzer and high‑luminance flashing light alerts.
- Resin insulation rod designed for disassembly to drain water.
