Overview

Enviro Forest ohmmeter resistance tester are high precision and high stability DC resistance meters that adopt high-performance 32dgt ARM microprocessor control. They feature a 3.5 in (8.89 cm) true-color LCD display in both Chinese and English, making them easy to operate. These meters are widely used for measuring all kinds of high, medium, and low-value resistors, various switch contact resistances, connector contact resistances, relay packages, and contact resistances, transformers, inductors, motors, deflection line winding resistances, welding contact resistances, resistance wires, and metal riveting resistances of vehicles, boats, airplanes, printed circuit lines, and crack detections, among other applications.
