Usually you will find haze and transmittance standards of ASTM D1003, ISO 13468, & JIS K7105.

Zero calibration of a hazemeter is a critical pre-measurement procedure to ensure the instrument’s accuracy by resetting its baseline to "zero" when no haze or light attenuation is present.

1. Align the hazemeter’s measurement window with air or a black background, ensuring no objects block the window.

2. Press the hazemeter’s zero calibration button and wait for the instrument to complete automatic calibration. At this point, the instrument should display a zero haze value and a zero light transmittance value.

3. Observe the instrument’s display to confirm the zero calibration result stabilizes near zero. If the zero calibration is inaccurate, repeat the above steps multiple times until the displayed haze and light transmittance values stabilize near zero.

Perform 0-degree calibration before testing, this eliminates inherent instrument drift, environmental interference, or residual signal errors, ensuring subsequent measurements of transparent/translucent samples (e.g., plastic films，pvc, glass, coating, displays and cosmetic packaging) are reliable. Correct for minor instrument deviations caused by long-term use, temperature changes, or power fluctuations.

Standard light sources make sure that the results of color evaluations are comparable and consistent, no matter when and where the assessments are made, or the varying production runs.

Of course! Many portable, battery operated, and lightweight coating thickness gauges are available for on-site and field inspections. They provide quick and accurate results and portable gauges are ideal for construction, automotive, and industrial environments.

They provide accurate and repeatable assessments of color in various settings for the purpose of avoiding inconsistencies in mismatched items and ensuring steady production or branding.

Consistency in calibration is important to account for imbalances arising from wear and tear of the probe, probe pressure, variation from the environment, and fluctuations in daily usage. This is also necessary to maintain the best quality to various international standards.

A magnetic induction gauge measures galvanized coatings by sensing the zinc coating on steel and iron. The measurement tells how thick the protective coating is. This is done to ensure the prevention of rusting.

A colorimeter is a quick and inexpensive method to measure color and to control color in a material or solution. It is used to maintain color consistency during production and to check the chemical concentration. It also assists with the quality control of labs, food, textiles, and pharmaceuticals.

A service is made up of tub replacement, light source recalibration, internal cleaning, verification of service and color certification retention so that all compliance color standards are retained.
