Insulation Testers

Preventive maintenance is always a must, especially in motor instrumentation. Knowing before a problem arises, allows time for scheduled shut downs, instead of shutting your process down when you need it the most. Yokogawa offers many varieties of Insulation testers, from our “Hand Crank” version to our Analog and Digital 1000V versions.

  • The MY40 insulation tester is used to measure the Insulation resistance that represents the state of insulation of electric equipment or circuits; It is one of the important measurement parameters in terms of safety and security. The MY40 comes with 4 voltage/resistance ratings on an easy-to-view large display, and incorporates a double-action safety mechanism to keep the user from harm.

  • The 2406E Analog Insulation Tester:
    Analog models with two and three rating
    AC voltage measurement
    Automatic discharge
    Sky blue EL backlight
    Increased safety (covered battery charger)


After a disastrous 2009, the large publicly held test companies enjoyed booming business in 2010.
