Product Series : Wearable Proximity Alarm
After the operator wearing the alarm, when approaching the certain distance from the high voltage charged object,the alarm will emit sound and light alarm according to the safe distance corresponding to the voltage level, reminding the electrical worker paying attention to safety and avoiding high-voltage electric shock accident.This product can also be used for line fault detection and electroscope use.
Alarm Voltage Range: 1kV ~ 500kV
Voltage Detection Method: Non-contact
Protection Level: IP54
Sound & Light Alarm
Product Introduction
EM1860 Wrist Type High Voltage Approach Electricity Alarm, also known as wearable near-electric alarm, which provides a safe, practical and convenient new-type high voltage alarm device for near-electric operators. When work on electric device without turning off electricity, the safety distance between the operator and the live object should not be lower than the requirement of relevant work regulation. After the operator wearing this alarm, when approaching the certain distance from high voltage live object, the alarm will emit sound and light alarm according to the corresponding safety distance of the voltage level, reminding electrical worker paying attention to safety and avoiding high voltage electric shock accident.
EM1860 Series Wrist Type High Voltage Approach Electricity Alarm has two options: high voltage alarm (suitable for 1kV and above) and low voltage alarm (suitable for 1kV and below), adopting with non-contact induction technology, accurate alarm, energy-saving and durable, with standby time up to 12 months. The alarm has unique automatic triggering detection function to ensure the safety of live working personnel. This alarm are widely used in near-electric workplaces such as power, railway and industrial mining enterprise.
ETCRMETER is a high-end brand of ETCR. All products are manufactured by ETCR, which also provides technical support and after-sales service.
