Surface resistance testers can also be known as surface resistance meters, ESD testers, surface resistivity meters and anti-static surface testers. They are small portable instruments for measuring both resistance to ground and specific surface resistivity. The devices are heavily used in electrical manufacturing assembly areas as a safety tool, this is to prevent damage to other equipment, such as integrated circuits, that might be caused by sparks from excess ESD (electro-static discharge)
Most surface resistance testers are pocket sized test instruments and use either red or green LEDs and an audible alarm to indicate whether the measured resistance is within a specified safe range outlined by EN 61340-5-1. Regular testing of ESD wrist straps, grounding cords, heel straps and ESD boots worn by production staff is essential to control static around sensitive electronic components.
Owing to the extensive use and safety critical nature of these devices, leading manufacturers like Anti-Stat advise that calibration is done every six months. Ultimately calibration frequency and maintenance schedules are down to quality procedures within individual organisations, but Calibrationhouse always advises following manufacturer guidance. Please contact us if you would like advice on calibration periods of these or any other test instruments you are unsure on.
Our surface resistance tester calibration service is available onsite at customer premises or via a rapid turnaround service at our lab. Pricing is competitive and UKAS level certification is available across the board.
