Support both ASTM and ISO standards

The instrument supports both ASTM and ISO standards to meet the testing standard requirements of different users.

Measurement of color difference, haze, light transmission, spectral transmittance curves

The instrument can measure haze, transmittance and color of various transparent and semi-transparent materials such as plastic, glass and films, and it can also display the spectral transmittance curve.

7-inch large capacity touch screen

Adopt a 7-inch capacity touch panel with human-machine interaction interface for convenient operation.

Spectral curve display of light transmittance

Convenient to identify the transmittance performance of materials in different wavelength bands, thus knowing the optical performance and materials color.

Good repeatability

The instrument has good repeatability, with haze repeatability ≤ 0.03, light transmittance repeatability ≤ 0.05, and color difference repeatability ≤ 0.03, which is comparable to imported brands.

Ensure that it can pass the National Institute of Metrology measuring

The haze measurement and color difference measurement of the instrument are guaranteed to pass the inspection of the National Institute of Metrology.

Dual aperture design

It adopts 14mm and 5mm dual-aperture design, and the appropriate test aperture can be selected according to the size of the material being tested.

Spectral sensors with fitting algorithms provide high accurancy

It adopts spectral sensor with self-developed fitting algorithm scheme, instead of the silicon photodetector of the traditional haze meter, which has higher precision and more stable measurement.

Adoption of aerospace aluminum components

The core components are made of aviation aluminum, with high-precision CNC machining process, so that the alignment between the light source and receiver has micron-level accuracy, to ensure the instrument repeatability and high precision.

Open measurement area

The instrument has an open measurement area and has two measurement states: vertical and horizontal. When placed horizontally, a positioning bracket can be optional.

Three standard lighting sources

The instrument meets the requirements of haze, transmittance and color measurement under three standard lighting sources: CIE-A, CIE-C and CIE-D65.

Dual measurement mode

Simple measurement and comparative measurement modes can be switched at will, and the operation is clear at a glance.Qualification can be automatically determined by setting the tolerance value.

Equipped with PC software

The instrument is equipped with PC software, which can be connected through the USB interface, can perform online measurements, and supports data export and storage.

Uninterrupted by ambient light

The instrument has unique signal processing technology to ensure that the measurement results are not interfered by external ambient light.

Full spectrum LED light source, long life, no need to replace for ten years

Compensation optical path, which is stable and allows long-term calibration.

Extra large storage space, can store 1,000 measurement records.
