# Detectors Detectors enable coaxial transmission loss, gain, and power measurements when you pair them with the correct electronic test equipment. The type of detector you need depends on the test equipment you’re using for your application. Radiofrequency (RF) detectors are precision instruments used for many laboratory applications, as are type K detectors, microwave detectors, and error detectors. For more information about which used or refurbished detector is right for your needs, call ValueTronics at (800) 552-8258. ## Products in this collection - [MD10 Extech Detector New](https://valuetronics.com/products/md10-extech-detector-new) -
