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.
Align the hazemeter’s measurement window with air or a black background, ensuring no objects block the window.
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.
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.
Turn on the hazemeter and check if the instrument’s display screen shows normally and if the buttons are responsive.
Verify that the hazemeter’s battery power is sufficient. Replace the battery or connect an external power supply if necessary.
Confirm that the instrument’s measurement mode is set correctly. Select the appropriate measurement unit and range based on actual needs.
A haze meter should be calibrated every 6 months, or more frequently if used for certain quality control processes.
Samples should be cleaned, dried, and scratched-free to obtain consistent haze measurements.
Ambient light may affect the test results and must therefore be kept to a low level for accurate haze meter results.
Each haze test can take from 3 to 10 seconds depending on the device and the type of sample.
We provide professional training to customers along with user manuals for the proper operation and maintenance of haze meters. If you have any problems during use, you can contact our experts who will quickly help you solve the problem
Inconsistent results from a haze meter can stem from issues like calibration, dusty haze meter optics, inadequate power supply, and improper measurement technique. If you have any questions, you can contact our Haze measurement experts
To take care of a haze meter to make it last longer, ensure that it is cleaned, recalibrated regularly, and stored in a dry, dust-free place.
A haze meter is precise and accurate if the sample is clean, there is a light contamination, and the sample is condition.
Usually you will find haze and transmittance standards of ASTM D1003, ISO 13468, & JIS K7105.
Follow the calibration steps form 3nh. Don’t touch the sample and drop the measurement light to eliminate external light.
Haze captures the scattering of light, transmittance measures the light that passes through a said material.
Take into account the measurement range, type of samples, needed precision, any relevant standards, and your industry.
Because of its unmatched precision, ease of use, adherence to global standards, and consistent long-term reliability.
Spectrophotometers can only measure haze if it has haze measuring capabilities, as many measure color and transmittance.
Accurate readings can be obtained by keeping the sample clean, regular calibration, control of ambient light and appropriate measurement settings.
Haze measurement can be distorted by scratches on the surface, dust, temperature, and light.
Plastics, glasses, films, coatings, and packaging materials are common uses of hazemeter to monitor consistency and quality.
To use a haze meter, the device must first be calibrated and then it will display the haziness and transmittance values.
