IR4018 - Analog Insulation Tester

Product information IR4018 - Analog Insulation Tester


Key Specifications

  • Insulation resistance measurement (1000 V DC) up to 2000 MΩ
  • Voltage measurement up to 600 V AC 
  • Measurement category: CAT III 600 V 
  • Display: illuminated analog meter

The HIOKI IR4018-20 is a rugged analog insulation tester designed for reliable insulation resistance testing in electrical installations and equipment. With a 1000 V DC test voltage and a measurement range up to 2000 MΩ, it is particularly well suited for applications with higher insulation requirements. 

The easy-to-read illuminated analog meter enables quick and confident evaluation of insulation measurements, even in low-light environments. For added safety, the integrated live circuit indicator reliably warns when hazardous voltage is present. After testing, the automatic discharge function ensures safe discharge of the device under test. 

Built for demanding everyday use, the IR4018-20 is drop-proof (1 m onto concrete) and meets the requirements of CAT III 600 V. Its IP40 protection rating (excluding terminals) makes it well suited for typical maintenance work. In addition, the instrument features AC voltage measurement up to 600 V and a practical housing design that allows test leads to be stored quickly without disconnecting them. 

A wide range of optional accessories is available for the IR4018-20, including test pins, alligator clips, and additional connection adapters. Especially useful are the remote switch test lead (L9788-10) or the complete set including an additional black lead (L9788-11).
