Rent the Keytek MZ15 ESD Simulator/Gun by Thermo Fischer Scientific allows for electrostatic discharge testing to  air discharge to 15kV and contact mode to 8kV with simple, intuitive operation. This gun/simulator includes ISO 17025 accredited calibration and air and contact tips. The MZ-15 also known as the Keytek Minizap, is light weight and durable lending itself well to long-term use in harsh environments in the field. It is well known within the industry and testing criteria is changed by turn nobs.

This electrostatic discharge generator is ideal for testing to EN IEC 61000-4-2, ANSI C63.16, and others through manipulation output voltage selection and pulse repetition rate selector knobs. The interchangeable plug-in tips allow for testing to different standards. The polarity can be switched on the test equipment by switching the output polarity selection on the side of the equipment. 

The Minizap ESD simulator does not use a voltage multiplier, and won’t introduce testing errors and uncertainties due to streams of artificial, high-level ESD multiples generated by a human discharge or by other simulators. The Keytek simulator is easily mounted on a tripod allowing for tests to be ran consecutively without user fatigue. Real time voltage is displayed via the actual output voltage indicator with accuracy typically at +/- 3% for this product.
