Fluke Tools

The CAT rating indicates the voltage surges a meter can withstand. CAT III 600V/1000V is intended for three-phase distribution within buildings. CAT IV 600V is required for measurements taken directly at the source of the low-voltage installation (such as electricity meters). Always use a Fluke meter that is suitable for your working environment to protect yourself from life-threatening arc flashes.

Yes, if you work to ISO standards or in sectors where precision is crucial, we recommend having your Fluke instrument calibrated annually. Although Fluke devices are highly stable, calibration ensures that your meter continues to perform within the manufacturer’s specifications and that your official measurement reports remain valid for inspections.

A True-RMS multimeter (such as the Fluke 179 or 87V) accurately measures the effective value of alternating current, even when the sine wave is distorted by modern electronics such as LED lighting or laptops. In such cases, a standard meter often displays an incorrect reading. A Fluke True-RMS meter is indispensable for professional maintenance.

For HVAC work, the Fluke 116 or the Fluke 902 FC clamp meter are both good choises. These instruments feature functions for measuring flame sensors (microamperes) and temperature, which is essential for diagnosing heating and cooling systems.

With Fluke Connect®, you can send measurement data wirelessly from your meter to your smartphone. This allows you to read measurements remotely (which is safer!), log trends in the cloud and share reports instantly with colleagues or customers without having to enter the hazardous area of an installation.
