A3-3500 Metric Handheld Tachometer htm - 500M

The mechanical hand-Tachometers htm are designed to accurately measure RPM and surface speed on a wide range of applications.

Features:
• NO BATTERIES required!

• Rubber shell on housing provides extra protection and improved grip.

• Over-sized 3" Dial (70 mm) uses 2 separate color scales making reading RPM (black) and Surface Speed (red), quick and easy.

• Accuracy of ± 0.5% Full Scale.

• 3-Position Range Selector Switch provides highest possible resolution for each application.

• Memory button holds pointer in "last" position until reset.

Mindful of the need to operate tachometers in areas where there is sometimes a risk of explosive atmospheres due to either dust particles or gas, our engineers have carried out modifications to enable this version to be certified for use in ATEX zones without compromising the capability of the original design. The ATEX approved version is suitable for zone 1 use, in all gas groups with a temperature class of T4 and is also suitable for mining applications I M2 c.
