Fluke T90 Voltage & Continuity Tester

The Fluke T90 is a compact and affordable Fluke voltage and continuity tester. Made in the UK, this tester features large easy to use buttons, bright backlit LED indicators and clear audible indication, which alert the user to the presence of voltage.

Safety is the number one priority with all Fluke Testers. The Fluke T90 tester includes the same super hard wearing cable technology as all other Fluke T series testers. The cable is tested to 5,000 bends at 150° rotation, which is over three times the industry standard of 45°.

The Fluke T90 tester operates off 2 AAA batteries which add very little weight. It is best practice to prove the Fluke T90 voltage and continuity tester on a known source before and after checking for the presence of voltage.

Fluke T90 key features

  • Clear visual and audible indication of voltage present
