Description

Amprobe AMP 330

The Amprobe AMP-330 is a versatile clamp-on amp meter, ideal for electrical motor maintenance and HVAC testing in high-voltage industrial settings. As the top model in the AMP-300 Series, it incorporates all the features of the AMP-320, with added benefits like a built-in work light, peak hold, and enhanced safety ratings of CAT IV 600V and CAT III 1000V. Its large 2.0-inch (51 mm) jaw makes it perfect for handling various wire sizes.

For HVAC technicians, the AMP-330 provides essential functions such as temperature and capacitance measurements along with DC microamps for testing flame sensors. Core motor testing features include motor rotation, 3-phase sequence testing, and inrush current measurement to monitor motor startup.
