BRISTOL, PA — TESCO Metering has unveiled a new high-voltage safety device designed to help protect transit and utility workers operating in some of the most dangerous electrical environments in the field.
The company announced the launch of its 4E2-1 Third Rail Voltage Detector, a specialized instrument engineered to detect electrical potential between energized third rail systems and ground. The device is aimed at transit authorities and utilities that rely on clear, immediate voltage confirmation during inspection, maintenance, and testing operations.
As rail and utility systems grow more complex and operate at higher voltages, worker safety has become an increasing concern. Third rail systems, in particular, pose unique hazards that require tools capable of delivering unmistakable feedback before technicians begin work. The 4E2-1 is designed to meet that need by combining redundant detection circuits with both visual and audible alerts.
According to the company, the detector uses two independent circuits with high-visibility LED indicators to confirm the presence of voltage, while a built-in audible alarm provides an added layer of situational awareness. The instrument operates on alternating or direct current systems up to 1,500 volts and allows testing at distances of up to four feet, helping reduce worker exposure.
The device is built for harsh field conditions, featuring a moisture- and oil-resistant phenolic handle and housing, sealed internal electronics, stainless steel prod tips, and an integrated rubber hand guard to promote safe handling.
TESCO Metering said the 4E2-1 was developed specifically for electrified rail and high-voltage utility environments and is already in use by Bay Area Rapid Transit and other transit systems. The company said its rugged construction and redundant detection capabilities allow operators to verify voltage conditions quickly and confidently before entering hazardous work zones.
Working around high-voltage infrastructure leaves no margin for uncertainty, said Tom Lawton, president and chief executive officer of TESCO Metering, adding that the detector was engineered to provide clear, reliable confirmation of voltage presence so workers can make informed safety decisions before beginning their tasks.
The company said the new detector reinforces its focus on safety solutions for critical infrastructure, where accurate voltage detection can mean the difference between routine maintenance and catastrophic injury.
