Product Description
LAUNCH ES300 High-voltage Insulation Resistance Tester Supports Short-circuit Buzzer Tests
Product Introduction:The ES300 is a high-voltage insulation resistance tester, used for insulation resistance, AC/DC voltage, resistance, and short-circuit buzzer tests.
An insulation resistance tester, commonly known as a megohmmeter, is a portable instrument specially designed to measure the insulation resistance of electrical equipment and lines. It outputs high-voltage DC(with adjustable voltages of 500V, 1000V, 2500V, and 5000V.
), applies it across the insulation medium under test, and converts the detected weak leakage current into an insulation resistance value, so as to determine whether the insulation layer has hidden risks such as moisture, aging, damage, or breakdown.
It supports Insulation testing of high-voltage components such as new energy high-voltage wiring harnesses, battery packs, motors, electronic controls, cables, and power distribution boxes.
NOTE: Not suitable for testing live components; power must be cut off and the components fully discharged before measurement.
Product Features:
Design meets the following safety standards:
IEC 61010-1 (CAT IV 600V, Pollution Degree 2)
IEC 61010-031 (Requirements for hand-held probes)
Insulation test range: 0.1 MΩ – 60 GΩ.
Insulation test voltage: 500 V, 1000 V, 1500 V, 5000 V.
AC/DC voltage: 0.5 V – 600.0 V.
Short-circuit buzzer: <50 Ω.
Low resistance test range: 0.1 Ω – 6 kΩ.
Automatic discharge and voltage output warning functions.
When testing the insulation resistance of capacitive loads, the charge stored in the circuit loop is automatically released after the test is completed, and the voltage display can be used to check the discharge status.
Backlight function helps with operation in dim places or at night.
Circuit warning symbol and audible warning.
Circuit detection function: when the voltage exceeds 30 V, the user is reminded to stop the insulation test.
Auto power-off (after 20 minutes of no operation) and battery check function.
Timed measurement function: automatically performs measurement at the set time.
Polarization Index (PI) measurement.
The polarization index is measured through the meter's automatic measurement function, which automatically measures the resistance at 1 minute and 10 minutes respectively. Pass/Fail is automatically displayed at the two time points.
Dielectric Absorption Ratio (DAR) measurement.
The dielectric absorption ratio is measured through the meter's automatic measurement function, which automatically measures the resistance at 1 minute and 30 seconds respectively. Pass/Fail is automatically displayed at the two time points.
6000-count LCD display with analog bar.
Max/Min, peak, relative value, and data hold functions for DC/AC voltage measurement.
Power supply: 8 x 1.5 V (LR14/R14).

Product Comparison Between ES300 and 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. |
