Description

The Klein Tools ET900 is a USB digital meter designed for common standard USB-A (Type A) ports, including those that support Qualcomm Quick Charge®. This device accurately measures and displays voltage, current, capacity, energy, and resistance simultaneously. It can be used with any USB-A port that delivers power and is powered directly by the USB port, eliminating the need for batteries.

It offers continuous monitoring for up to 1000 hours and can store and recall up to 10 readings. The ET900 features voltage and current overload detection and a high-resolution LCD screen for visibility in low light. Its durable cable allows for easy access to hard-to-reach ports, and its rugged, pocket-sized design is built to withstand a 6.6-foot drop.
