Der LAUNCH ES300 ist ein Hochspannungs-Isolationsmessgerät für die Messung des Isolationswiderstands, von AC- und DC-Spannungen sowie von Widerständen. Darüber hinaus verfügt das Gerät über eine Durchgangsprüfung mit akustischem Signal zur Erkennung von Kurzschlüssen. Der ES300 ist die weiterentwickelte Version des LAUNCH ES200.

| Model | ES300 | ES200 | Remark |
| Function | The ES300 professional high-voltage insulation resistance tester is a hand-held instrument mainly used for AC/DC voltage measurement, resistance measurement, short-circuit buzzer testing, and insulation resistance measurement. | The ES200 is an insulation resistance tester designed with microcomputer technology as its core, combining large-scale integrated circuits and digital circuits. | Both can measure AC/DC voltage (<600V) and insulation resistance (with continuous measurement and timed measurement). The ES300 adds low resistance measurement (0.1Ω–6kΩ) and short-circuit buzzer (<50Ω), and adds Polarization Index (PI) and Dielectric Absorption Ratio (DAR) measurement to insulation resistance testing. |
