Martindale CP201-32 Industrial Socket Tester
The Martindale CP201-32 Industrial Socket Tester delivers fast and reliable checks for industrial single phase sockets. It helps identify wiring faults quickly, which supports safer working environments and reduces downtime.
Its clear LED layout mirrors the plug pin configuration, so users can read results at a glance. In addition, the built-in reference chart allows quick fault identification without needing extra tools or guides.
Clear Fault Identification
Using three bright LEDs, the Martindale CP201-32 provides instant visual feedback on wiring conditions. As a result, users can detect common issues quickly and take action without delay.
Furthermore, the unit highlights voltage conditions by indicating when levels rise above 270V or fall below 195V. This ensures that both wiring faults and supply issues are easy to spot during testing.
Durable and Practical Design
The Martindale CP201-32 is built with a strong ABS housing, offering long lasting durability in demanding environments. It is also lightweight and compact, making it easy to carry and use on site.
Although it is not a replacement for full installation testing, it serves as a dependable first line diagnostic tool. Therefore, maintenance teams can use it to quickly assess socket safety before further inspection.
