Summary
There are many multi-meters with amp clamps available in all price ranges.
Many techs will have a personal favorite with no single unit being the best.
Fluke units are usually considered the top brand name but many other units work just as well.
HVAC service technicians are often divided when it comes to multi-meters.
Reading through the reviews on sites such as Amazon or forums is always a good idea to see if it is the right fit for you.
Finding a good HVAC meter that helps you get the job done quickly and reliably is always the goal.
Low amperage and small wire gauge is hard to read on large clamps. For the best readings you’d need multiple size and rated meters, not very practical 🙂
