The LS155 Color Haze Meter is a lab-grade optical instrument used to measure how transparent or colored a material is. It’s commonly used in quality control for materials like plastics, glass, films, liquids and more to quantify optical properties that the human eye can’t reliably judge.
🔍 Key Features
✔ Multi-parameter optical measurement
It can measure haze, light transmittance, color (CIE Lab, LCh, Yxy), clarity, turbidity, and even Pt-Co (platinum-cobalt) color for liquids — plus it can display the spectral transmittance curve.
✔ Meets Industry Standards
Supports ASTM D1003 and ISO 13468, so the results are compliant with widely accepted international testing methods.
✔ Dual Aperture Design
Includes 5 mm and 14 mm apertures, letting you test both small and larger samples accurately.
✔ Smart, Easy Operation
7-inch capacitive touch screen with a human-machine interface. You can do simple or comparative tests and set tolerance limits.
✔ PC Connectivity
Connects via USB (Type-C) and comes with software for data export, reporting, and analysis.
✔ Designed for Accuracy & Stability
It uses a full-spectrum LED light source and a spectral sensor with fitting algorithms, rather than traditional silicon detectors, leading to better precision and repeatability.
✔ Robust Build
Core optical parts are made with aviation-grade aluminum and CNC machining, giving micron-level alignment and better long-term stability.
✔ Ambient Light Filtering
Unique signal processing ensures that external ambient light doesn’t mess with the results.

The conical mandrel bend tester is used to determine properties of a coating. Resistance to cracking
detachment from its substrate and its elongation during the test. Conical mandrel test is also known as
standard method for assessing the flexibility and the adhesion properties of coatings when these are
subjected to bending stresses This is accomplished by bending the test material around a conically
shaped metal bar. The conical mandrel bending test is a commonly used for testing for painted or
coated panels. Conical Mandrel Bend Tester is widely recommended to test the resistance of a paint, coating, varnish
to evaluate cracking or detachment from a metal panel. It is suitable for use with metal panels up to
0.8mm thick (flexible substrates up to 5mm thickness) e.g. polythenes or synthetic rubber. The
apparatus consists of a steel mandrel 203mm in length and tapering from 38mm to 3mm in diameter. It will accommodate test panels up to 19cm x 11cm in size. A graduated scale on the clamping bar
indicates the mandrel diameter at which failure has occurred. When this diameter is added to the
thickness of the panel used, the percentage elongation can be calculated. Conical mandrel detects
common failures of coating shows cracking or flaking after bending. Can be used in accordance with
DIN ISO EN 6860, ASTM D522, BS 3900 E11, DIN 53150
