Electro-Technic Products

At Electro-Technic Products we are passionate about selling the world’s best handheld and manufacturing line spark testers, pinhole (holiday) detectors, and corona surface treaters along with the highest quality science and education products. Our story begins in 1942 when ETP was focused on serving the neon light industry through proprietary vacuum testing technology. ETP’s founders leveraged this innovative technology to develop what we offer today, high quality spark and pinhole testers (holiday detectors), corona surface treaters, vacuum vial testers and a vast array of science and education products known for their quality by high schools and universities worldwide.
