Price Match Guarantee & Advice

This small size clamp meter is perfect for testing in engines and other tight applications. Its narrow jaw opening of 0.8" (22mm) makes it easy to connect to engine wires and other conductors.

The MA145 is the upgraded version of the MA140. The main difference between the two products is this model includes the ability to measure both AC and DC current, while the MA140 only measures AC. The MA145 also includes a unique Auto Sense mode which will automatically detect the input and activate the correct mode (either AC or DC).

Before testing, users can also use the MA145's built-in non-contact voltage detector to detect the presence of voltage from 80 to 600V. Other additional features include a low pass filter (LPF) for measurements of variable frequency drive signals, inrush current measurements and smart data hold with audio and visual alerts when a value is 50 digits outside of the held value.
