HW300-MAX Digital Coating Thickness Meter — Precision Measurement for Metal Surfaces
The HW300-MAX Digital Coating Thickness Gauge delivers professional-grade, non-destructive measurement of paint, enamel, chrome, anodized coatings, and more on both ferrous and non-ferrous metal substrates. Whether you're in automotive detailing, manufacturing, metal processing, or quality inspection, this compact and highly accurate instrument gives you reliable readings every time — in the lab, on the shop floor, or in the field.
Key Features
- Wide Measurement Range: 0–2000 µm — handles everything from thin primer coats to heavy industrial finishes
- Super Precision Resolution: 1 µm for highly accurate readings on ferrous (FE) and non-ferrous (NFE) substrates
- Automatic Substrate Detection: Instantly identifies whether the base metal is ferrous or non-ferrous — no manual mode switching required
- Non-Destructive Testing: Measures coating thickness without scratching, drilling, or damaging the surface
- CE & FCC Certified: Meets international safety and electromagnetic compliance standards
- Battery Level Indicator: Always know when it's time to replace batteries
- Auto Power-Off: Extends battery life when the gauge is not in use
- Compact & Portable: Small ABS housing fits comfortably in your hand or tool kit
- Wide Operating Temperature: Performs reliably from -10°C to 50°C

Frequently Asked Questions
Q: What types of coatings can the HW300-MAX coating thickness gauge measure?
A: The HW300-MAX can measure a wide variety of coatings including automotive paint, enamel, chrome plating, anodized layers, and other non-conductive coatings on both ferrous metals (steel, iron) and non-ferrous metals (aluminum, copper). Its 0–2000 µm range covers thin primer layers all the way to heavy industrial finishes.
Q: Does the HW300-MAX automatically detect the type of metal substrate?
A: Yes. The HW300-MAX features automatic substrate detection, meaning it can identify whether the underlying metal is ferrous (FE) or non-ferrous (NFE) without any manual mode selection. This makes it fast and easy to use across different materials.
Q: Do I need to calibrate the gauge before use?
A: The package includes 7 calibration sheets to help you verify and adjust accuracy for your specific application. Regular calibration is recommended to maintain measurement precision, especially when switching between different substrate types or coating materials.
Q: Are batteries included with the HW300-MAX?
A: No, batteries are not included. The gauge requires 2 × 1.5V AAA batteries, which are widely available. The built-in battery level indicator will let you know when the batteries need replacing.
Q: Can this coating thickness meter be used outdoors or in a workshop environment?
A: Absolutely. The HW300-MAX is designed for stable operation across a wide temperature range (-10°C to 50°C), making it suitable for use in laboratories, manufacturing workshops, and outdoor field inspections alike.
