Standard models are available in a range of sizes, starting from small desktop units which are roughly the size of 60 x 40 x 40 cm, and extending to larger units which are about 120 x 60 x 80 cm based on what you need them for.

Spectrophotometer, Colorimeter, Gloss meter, Haze Meters, Coating thickness meter, window tint meter, UV meter, Leeb hardness tester, Light booth, Color Test Chart, Ultrasonic thickness gauge. Threenh Technology company adheres to independent design, research and development, production and sales of various measuring instruments. 

Daylight, store light, home light, and UV fluorescence light sources are included in Pantone light boxes as D65, TL84, CWF, A, and UV. 

1. Turn on the hazemeter and check if the instrument’s display screen shows normally and if the buttons are responsive.

2. Verify that the hazemeter’s battery power is sufficient. Replace the battery or connect an external power supply if necessary.

3.  Confirm that the instrument’s measurement mode is set correctly. Select the appropriate measurement unit and range based on actual needs.

The number of reflected light is a measure assigned by a gloss meter as a gloss unit (GU). It is a normalized quantity in which 100 GU is normally a perfect reflection at 60°, and 0° GU is a full diffusion.

Take L*a*b* readings of two samples using a colorimeter or spectrophotometer and calculate color difference using the 3 formula (Delta E). The difference in 0 is the reported Delta-E, which shows how visible the change is, whereas the thresholds define the acceptability as per the application requirements.

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.

 Color is measured using devices such as colorimeters, spectrophotometers, and spectroradiometers. Colorimeters are easier and good for simple color quality tests. Whereas spectrophotometers yield detailed spectral information. Hence, suitable for laboratories and industries.

To keep the light box calibrated and to ensure accurate and steady lighting, clean the inside, replace the lamps when needed, check the calibration and record the hours use

Depending on model and location, delivery time is usually 2-4 weeks for standard models and 4-6 weeks for built- to-order ones.
