1. INTRODUCTION

MT222 is a sensor for sensing AC High Voltage. It provides electric 
engineering personnel, power engineering personnel, firefighting 
personnel and instrument equipment workers with prominent warning 
when approaching high voltage and for taking necessary safety action, 
preventing illusion and misjudgment which could lead to electric shock to 
person.
When a person wearing MT222 is approaching high voltage source or 
equipment, the sensor will detect automatically and buzzer will generate a 
"BeBe" sound for warning and LED will flash to remind operators that the 
user is approaching a high voltage sauce and special attention shall be 
given to the safety of operations.

2. FEATURES

●  Designed for detecting un-shielded cables. If the shielding of the cable is 

connected to the ground, it can't work.

●  Compact, easy to wear and convenient in use.
●  Usable both indoor and outdoor.
●  Water-proof design. (IP65)
●  Equipped with self-testing functions.
●  Sound and flash light warning on different frequencies varied positively 

with sensed voltages.

●  Able to sense all kinds of AC High Voltage System.
●  Low power consumption.
●  Meets : EN 61326-1.
●  CE Certified.
●  Voltage detection :
