Hioki 3490 Analog Insulation Tester

Hioki 3490 Analog Insulation Tester

The 3490 is a traditional analog pointer insulation tester for electricians and maintenance engineers who prefer a direct pointer reading to a digital display. The analog scale gives an immediate visual indication of insulation condition across the full measurement range, with a backlit scale for use in dark panels and cable trays. Three test voltage ranges cover the full spectrum of standard electrical equipment testing.

Key Features

• 3 test voltage ranges: 250V, 500V, 1000V DC
• Insulation resistance up to 4000 MΩ (at 1000V range); 100 MΩ at 250V/500V ranges
• Continuity check at 3Ω range via 200mA test current
• AC voltage measurement up to 600V — live circuit detection before testing
• Analog pointer display with backlight — easy to read in dark environments
• IP40 dustproof (terminal excluded)
• Drop proof design
• CAT III 600V safety rating
• EN61010 (Safety), EN61326 (EMC)
• LR6 alkaline battery ×4, 20 hours continuous use
• 162 × 167 × 52mm, 840g

IR4016-20 and IR4017-20 Variants

The analogue insulation tester range also includes the IR4016-20 (500V, single range, 1MΩ to 100MΩ) and IR4017-20 (500V, single range, 1MΩ to 1000MΩ) for simpler single-voltage applications, and the IR4018-20 (1000V range).

Applications

Motor insulation testing, cable insulation checks, switchgear testing, transformer winding insulation measurement and general electrical maintenance where analog indication is preferred.
