Three-in-one multifunction tester measures tyre pressure and records battery and alternator voltage

Very easy to use, the tyre pressure gauge function is useful as it lets you record the pressure of each individual tyre. First select the unit of tyre pressure: PSi, BAR or kilograms-per-square centimetre. Then take the pressure of the first tyre and press the RECORD button. This keeps a record of this first tyre pressure and then each subsequent tyre pressure for up to four tyres.

It’s also very easy to check the power of your car’s main battery; simply plug into the 12 volt socket, turn on the ignition and the tester displays the battery voltage and status (low, mid or full). Switch to alternator test mode, switch on the engine and rev to 2000rpm, and the alternator voltage output is displayed.

A useful little tester to keep in the glove box and available now from your local Laser Tools supplier.
