Inductive high-voltage electroscope high- voltage test pencil high- voltage test pencil high-voltage sensor
Product model: 276SHD
high-voltage electroscope with telescopic high-voltage test rod
This model 276SHD high-voltage electroscope is mainly used to detect the presence of voltage in the AC cable.
Retractable insulation rods allow high voltage lines to be detected at safe voltage distances. The instrument is small, lightweight and easy to hold.
The high voltage electroscope is also used for voltage detection of ordinary low voltage lines.
The instrument undergoes strict insulation and leakage testing to ensure the personal safety of the user.
High-voltage electroscopes are the right assistants for engineering installation and maintenance personnel in the power sector.
Instrument leather case with belt buckle that can be worn into the belt for easy carrying
product features:
◇ Retractable, small and lightweight, easy to carry.
Length: from 230mm to 880mm
Weight: about 140g
Easy to operate and easy to carry.
◇High pressure detection (inductive) For high-voltage line voltage detection in the extended state (1KV-24KV, the higher the voltage, the farther the distance), whether the cable is bare or sheathed (non-metallic shield) can be measured.
◇ medium pressure detection (inductive or contact type)
1KV-3KV communication, customers can choose contact or inductive measurement according to their needs or actual conditions on site.
Low-voltage detection (contact type)
Hold the indication part of the high-voltage electroscope detection head for low-voltage circuit voltage detection (80V-3KV). Before use, the measurement accuracy can be guaranteed by testing the 220V AC power socket.
◇ indicator light and buzzer
When the voltage is detected, the red high-brightness LED indicator flashes intermittently, and at the same time, the buzzer emits intermittent sound, which can be easily recognized during daytime and noise.
Waterproof
The probe is waterproof and designed to be fastened and will not affect the instrument due to dust, dirt and rain.
