Hw-400s Thickness Gauge High Precision Industrial Iron Aluminum Coating Thickness Gauge ABS Material 0-2000UM Measurement Range ±3UM Accuracy 142x68x53mm Black Red White
Hw-400s Thickness Gauge High Precision Coating Gauge for Iron and Aluminium 0-2000UM

This Hw-400s thickness gauge delivers high precision measurement for non-magnetic coatings on iron and aluminium substrates. With an accuracy of ±3 UM and a measurement range from 0 to 2000UM, it is suited for industrial quality assurance, automotive paint inspection, and general workshop use. The gauge is built with an ABS housing, measures 142x68x53mm, and operates from -10°C to 50°C. It is powered by two 1.5V AAA batteries (not supplied) and is available in black, red, or white.
Features and Construction

The Hw-400s combines practical measurement capability with a robust plastic body designed for portability and ease of use.
Material and Build
The gauge is constructed from ABS, a strong yet lightweight plastic that resists impact. This makes the instrument easy to carry and handle during routine inspection tasks. Its compact dimensions (142x68x53mm) allow comfortable one-handed operation.
Size and Practical Fit
At 142x68x53mm, the gauge fits comfortably in the hand or a tool pouch. The device is powered by standard AAA batteries, simplifying replacement when needed. The operating temperature range of -10°C to 50°C covers most indoor workshop and moderate outdoor conditions.
Uses and Placement

This thickness gauge is designed for measuring coating thickness on both ferrous (iron) and non-ferrous (aluminium) metal surfaces, supporting quality control and maintenance work.
Industrial and Professional Use
In manufacturing, the Hw-400s can be used to check paint, plating, or powder coating thickness on metal parts. The 0-2000UM range covers common automotive and industrial coating specifications. The ±3 UM accuracy supports consistent quality checks.
Workshop and DIY Use
For hobbyists and repair technicians, the gauge helps verify coating thickness on restored metalwork or used equipment. Its straightforward operation does not require complex setup, making it accessible for occasional use.
Benefits and Buying Value

The Hw-400s provides essential measurement capability without unnecessary complexity, offering good value for professionals and enthusiasts alike.
Accuracy and Reliability
The ±3 UM accuracy gives confidence in readings, reducing guesswork when assessing coating thickness. This is particularly useful for matching paint layers or determining if a coating is within specification.
Why Choose This Product
With a clear measurement range, solid ABS construction, and simple battery power, the Hw-400s delivers practical performance at an accessible price point. Its availability in three colours allows a small degree of personal preference or job-site colour coding.
