NSG 437 Testing Accessories



The Teseq NSG437 ESD gun allows for testing to 30kV air and contact (150pf/330Ω) with a simple and easy to use design. Transient Specialists is the only authorized sale partner of Teseq ESD simulators in the United States. It provides functions very similar to its competitors the Haefely ONYX 30 and the EM test ESD NX30.  It includes an accredited calibration and technical support is included in the rental equipment price. This equipment is an ideal solution for field testing as voltage levels can be easily modified for efficient testing to and above several standards.

This test equipment allows for manipulation of testing parameters for EN IEC 61000-4-2, ANSI C63.16 through the use of the display. It is designed to sit comfortably in the operator’s hand, with operating conditions constantly displayed and accessible on a bright, clear color touch display. This product is unique in offering an activity log where the number and type of simulations can be verified by time frame and standard.

The NSG 437 ESD Simulator has a color touch display and keypad for parameter input shows the precise functional and test data with user-selectable language for convenient and safe operation worldwide. The simulator contains variable threshold selection for accurate discharge detection. This detection feature can be switched off when testing EUT’s with non-conductive surfaces, such as plastic housings. This product is part of the Teseq electrostatic generator line of products including the NSG 435 and NSG 438.
