    Description

    Hasegawa HST-70 Telescopic Special High Voltage Detector (AC 20kV ~ 80kV)

    The Hasegawa HST-70 is a premier Special High Voltage Detector engineered for the safety of electrical workers handling overhead transmission lines and substation equipment. Manufactured in Japan, this device is specifically calibrated for a working voltage range of AC 20kV to 80kV, making it an essential tool for high-voltage diagnostics.

    The standout feature of the HST-70 is its telescopic FRP (Fiber Reinforced Plastic) rod, which is lightweight yet extremely durable. It allows technicians to maintain a safe working distance while testing, and easily retracts to a compact size for portability in a tool bag. Upon detecting live voltage, the device emits a distinct intermittent buzzer and flashes a bright red LED, providing unmistakable feedback even in noisy or bright daylight conditions.

    Hasegawa HST-70 Key Features:

    • Wide Detection Range: Specifically tuned for Special High Voltage (20kV – 80kV).

    • Compact & Portable: Telescopic mechanism makes it easy to carry and deploy.

    • High Insulation: FRP shaft ensures excellent dielectric strength and user safety.

    • Battery Check: Built-in test button to verify battery and circuit functionality before use.

    • All-Weather Reliability: Designed to perform in various environmental conditions (check manual for rain restrictions).
