Fluke T90 Voltage & Continuity Tester
The Fluke T90 Voltage & Continuity Tester is a compact two-pole electrical tester designed for troubleshooting and test and measurement in industrial, commercial and household environments. It provides backlit LED voltage indication from 12 V to 690 V ac/dc, plus continuity testing from 0 to 400 kΩ and single-pole phase testing. Large buttons, an audible indicator and a slim probe design support straightforward checks during everyday electrical work.
Voltage detection is automatic, with full-range polarity detection and an independent ELV indicator that can indicate voltages above 50 V ac or 120 V dc even without battery power or if the main circuit fails. A rugged double-insulated cable is tested to three times the required bend angle, while improved probe docking, a probe tip protector and UK GS38 sheaths support storage and probe protection. The built-in self-test, low battery indication and automatic transition to voltage mode when voltage is sensed provide additional checks during use.
Key Benefits
- Backlit LED indicators show nominal voltage levels from 12 V to 690 V ac/dc
- Visual and audible continuity indication supports quick continuity checks
- Voltage detection remains available for specified voltage levels even without battery power
- Large buttons provide simple control during electrical testing
- Dual-insulated cable is tested to three times the required bend angle
- Improved probe docking provides secure storage when the tester is not in use
- Single-pole phase testing supports phase detection without a touch electrode
- UK GS38 probe tip sheaths limit the exposed metal section of the probes
- Low battery indication alerts the user when the batteries require replacement
Common Applications
Fluke T90 Voltage & Continuity Tester is suitable for a range of electrical testing and troubleshooting tasks, including:
- Electrical troubleshooting
- Checking for the presence of voltage
- Verifying the absence of voltage before electrical work
- Continuity testing of cables
- Continuity testing of switches and relays
- Continuity testing of bulbs and fuses

Why Choose This Model?
The Fluke T90 is the basic model in the Fluke two-pole tester family for users who require voltage and continuity testing with LED indication and single-pole phase testing. Compared with the T110, T130 and T150, it does not include the switchable load, rotary field indication, electrical torch or vibration functions, while the T130 and T150 also add an LCD.

Specification Notes
- The single-pole phase test is not intended to determine whether a conductor is live; use the voltage test for this function
- Before continuity testing, perform a voltage test to make sure the unit under test is not live
- Fluke recommends a calibration interval of 1 year
