Fluke T90 vs T130 UK: Which Voltage Tester Should Electricians Buy?
The Fluke T90 and T130 are two-pole voltage and continuity testers that look almost the same and weigh the same. The T130 costs about twice as much on Amazon UK. Here is how Fluke T90 vs T130 compares, and which one makes sense for a UK electrician’s kit.

Buy the T130 if you work on commercial or industrial installs, or anywhere you want a digital readout, switchable load, phase rotation and the higher CAT IV 600V rating. Buy the T90 if you need a reliable, basic tester for proving dead on domestic work and want to save money.

The Key Differences
Display and readout
The T90 shows voltage on a row of LED indicators, which is enough to prove dead. The T130 adds a backlit LCD, so you read an actual voltage figure, which is easier when you are fault finding or checking supply voltage rather than just proving isolation.
Switchable load, vibration and phase rotation
The T130 has a switchable load, which helps when ghost or induced voltages give misleading readings, and it vibrates when the load is applied. Fluke also lists a rotary field indicator for phase rotation on the T130 from 100 V to 690 V, which matters on three-phase supplies. Fluke does not list either feature for the T90.
Safety rating and toughness
This is the biggest practical difference. The T90 is rated CAT II 690V and CAT III 600V, while the T130 is rated CAT III 690V and CAT IV 600V. CAT IV covers the origin of the installation, such as the supply side of the meter. The T130 is also IP64 against the T90’s IP54, so it is better sealed against water.
What stays the same
Both are the same size and weight at 280 g, run on two AAA batteries, test continuity from 0 to 400 kΩ, and carry a two year warranty. The T130 also has a small torch for dark cupboards and lofts, and lets you switch the continuity beeper off.
The Two Fluke Testers
1. Fluke T130
Best all-round tester for UK electriciansBacklit LCD, switchable load with vibration, phase rotation, torch, 6 V to 690 V AC/DC, CAT III 690V and CAT IV 600V, IP64.
2. Fluke T90
Best budget Fluke for proving deadLED indication from 12 V to 690 V AC/DC, continuity, CAT II 690V and CAT III 600V, IP54, two AAA batteries.
Which Should You Buy?
- Domestic electricians on a budget: T90 covers proving dead on most domestic work.
- Commercial and industrial work, or three-phase: T130, for phase rotation and the CAT IV 600V rating.
- Fault finding: T130, as the LCD and switchable load give you more to go on.
- Apprentices: check what your college and employer expect, then see our apprentice electrician tool list.

Frequently Asked Questions
What is the difference between the Fluke T90 and T130?
The T130 adds a backlit LCD, switchable load with vibration, phase rotation, a torch and a higher safety rating of CAT III 690V and CAT IV 600V. The T90 uses LED indicators only and is rated CAT II 690V and CAT III 600V.
Is the Fluke T90 good enough for proving dead?
For most domestic work, yes. It indicates AC and DC voltage from 12 V to 690 V. Always prove the tester on a known live source before and after testing, whichever model you use.
Does the Fluke T130 do phase rotation?
Yes. Fluke lists a rotary field indicator for phase rotation on the T130, from 100 V to 690 V. It is not listed for the T90.
Which is tougher, the T90 or T130?
The T130. It is rated IP64 against the T90’s IP54, and carries a higher CAT IV 600V rating.
