At most of time, we have stock in the factory. Generally it is 1-3 working days after the payment confirmed. After shipped, we will email you the tracking number. You can check the shipping status of your order on the website. If you are in urgent need, we can consider making special arrangement for you.

The best tool for measuring clear coat thickness is an ultrasonic coating thickness gauge. It is capable of measuring the thickness of each layer of paint on the vehicle, even the clear coat. This is common in automotive refinishing and inspection.


Take into account the measurement range, type of samples, needed precision, any relevant standards, and your industry.


Yes. However, for LED retrofitting to meet industry standards, color- calibrated LED modules must be used for accurate color rendering. We usually do not recommend customers to modify it themselves, as this can affect the accuracy of the color and cause unnecessary losses


To operate the haze meter, first calibrate the instrument, clean the sample, position it correctly in the holder, and initiate the measurement. The instrument then shows the haze and overall transmittance readings.

Yes, we offer free samples for test, you are welcome to order samples to experience our excellent quality and service.

Yes. Ultrasonic coating thickness gauges can pinpoint layers within a multi-coat system. Users can examine the separate thicknesses of a primer, base coat, and clear coat. In contrast, magnetic and eddy current gauges usually measure the overall thickness of the coating. 

Flickering lamps, color shifts, and uneven lighting are common faults, which can be corrected by changing the tubes, cleaning the interiors, and re calibrating the light system.

If there is uneven lighting, color shifts, and the light is not as bright as it was before, your lamps might have to be replaced. Recent light boxes used with Pantone, as well as Datacolor LightBooths, have usage timers that tell how long before a lamp needs to be replaced.


Colorimeters or spectrophotometers are used to measure liquid color. They measure light coming through or reflecting off the liquid. Readings can be reported as Lab*, RGB, or absorbance units. So that objective color analysis can be used to control quality, or to measure chemical concentration.
