Onova Tech Color and Haze Meter: a touchscreen control unit and a transmission chamber on one rail

Color and Haze Meter Color, haze and transmittance of transparent materials, on one bench

A benchtop instrument for transparent, translucent and parallel plane materials: plastic, film, glass and LCD panels. It reads haze, total and spectral transmittance and color through a 0/d integrating sphere, over 400 to 700 nm, and reports them on a 7 inch touchscreen. It carries the Onova Tech brand, ships with a Thai manual, and we calibrate it.

Everything the operator needs is on the instrument.

Calibrating at 0 percent and 100 percent, measuring, reviewing 20,000 stored readings and exporting them all happen on the unit's own 7 inch touchscreen, which runs Android. There is no laptop in the loop and nothing to install, which is what makes it usable by a production QC team and not only by a lab technician. Haze QC software for a PC comes with the instrument when you do want the data on a desk. These are the eight modules exactly as the home screen presents them.

Buying the instrument is the short part.

An instrument only earns its place when someone can show where its numbers came from. That is the work we stay for.
