About Digital Coating Thickness Gauge

Digital Coating Thickness Gauge

Ultrasonic Thickness Gauges are designed to improve safety and ensure reliability of material subject to corrosion or erosion. Corrosion gauges with their dual-element transducers are the primary inspection tool used to measure the remaining walls of components such as pipelines, pressure vessels, storage tanks, and numerous other applications.

Precision gauges use single-element transducers to provide the thinnest range and highest degree of accuracy possible. Common applications include metals and a variety of non-metals (i.e. glass, ceramic, plastic, etc.)

Dual Probe Versatility for Precise Measurement

Equipped with built-in and external probes, the gauge supports ferrous (F) and non-ferrous (NF) substrate measurements, making it suitable for a variety of industries. The ergonomic handheld design allows easy access to different areas, delivering precise, reliable coating thickness data essential for quality control and inspection in manufacturing, automotive, and more.

Intuitive Digital Operation & Calibration

The instrument features a large LCD display with backlight for optimal readability, along with simple push-button controls. Zero and two-point calibration methods ensure measurement accuracy across a range of coatings. Audible alarm alerts warn when set thickness limits are exceeded, supporting consistent compliance with international standards like ISO 2178/2360 and GB/T4956/4957.

FAQs of Digital Coating Thickness Gauge:

Q: How accurate is the Digital Coating Thickness Gauge for measurement tasks?

A: The gauge provides high accuracy with a measurement tolerance of (2%+1 m), a 1 m resolution, and reliable performance on both ferrous and non-ferrous substrates. This precision makes it suitable for applications in industrial inspection and quality assurance.

Q: What types of coatings and surfaces can this device measure?

A: It is designed to measure non-magnetic coatings such as paint, electroplating, enamel, and PVC on metal surfaces, including both ferrous (steel, iron) and non-ferrous (aluminum, copper) substrates, using either the built-in or external probe.

Q: Where can the Digital Coating Thickness Gauge be used?

A: This portable gauge is ideal for use in manufacturing plants, automotive workshops, quality control laboratories, and construction sites anywhere coatings need to be measured, especially across India.

Q: What is the process for calibrating the thickness gauge?

A: The instrument supports zero and two-point calibration for different substrate materials. Users follow on-screen prompts and use the calibration standards provided to ensure the measurements remain highly accurate.

Q: How does the audible alarm function enhance its usage?

A: The built-in audible alarm notifies users when the measured coating thickness exceeds set limits, helping maintain consistent application standards and quickly alerting operators during inspections.

Q: What are the benefits of using a handheld, battery-powered gauge?

A: Its compact, ergonomic shape and operation with two 1.5V AA batteries offer exceptional portability and convenience, allowing measurements in hard-to-reach spaces without the need for external power or data connections.

Q: When should the batteries be replaced in the device?

A: The gauge features a low battery indicator on its digital LCD display. When the indicator appears or if the device powers off prematurely, simply replace both AA batteries to ensure uninterrupted operation.
