NSG 438 Testing Accessories



The NSG 438, often just referred to as the NSG438, provides testing capabilities up to 30kV with easy to use and ergonomic design. Transient Specialists is the only authorized sale partner of Teseq ESD simulators in the United States. We also offer options for A2LA accredited calibrations upon request. This ESD Gun comes with 150pF/330Ω discharge network, commonly used for IEC 61000-4-2 and ISO 10605 testing.

This test equipment color touch screen allows modification many parameters including polarity selection, pulse repetition, counter functions, and discharge network detection. This Teseq product is unique in offering an activity log where the number and type of simulations can be verified by time frame and standard. It comes with discharge pistol, cradle for discharge pistol, high voltage base unit and battery pack, and many other accessories.

This pulse generator through the screen offers selectable language options, for convenience and world wide use.  We also rent and sell a variety of other Teseq products including the NSG 435 and NSG 437 providing solutions for a large spectrum of electrostatic discharge testing. For automotive testing we also carry the NSG 438 Auto, which provides 330pF/330Ω, 150pF/2kΩ and 330pF/2kΩ networks designed for a variety of both international and manufacturer automotive standards.
