Special tester for leather shoes

¥ Electricity Model: SUPER XRF 1050 Updated on: April 24, 2024 Product Catalog

Introduction to the special tester for leather and shoe materials Environmental protection is the trend of the world. The emerging environmental pollution events, such as the recent blood lead overproof event in Fengxiang, Shaanxi, have made people increasingly concerned about their own health and the harm of harmful elements to people. Countries around the world have successively issued relevant regulations to control the content of harmful elements in goods, Moreover, the limit value of harmful elements is decreasing. For example, the limit value of lead element in the European Union rohs directive implemented on July 1, 2006 is 1000 ppm, and the recently implemented U.S. Consumer Product Safety Act (hereinafter referred to as cpsia) reduces the limit value of lead element to 90 ppm. In the face of this market demand, adhering to the spirit of "Tianrui Instrument is meticulous" and adopting technology, we have specially designed super series x-ray fluorescence spectrometer.

TURBISCAN Lab Formulation stability analyzer multiple light scattering instrument

¥ Electricity Model: TURBISCAN Lab Updated on: August 31, 2021 Product Catalog

The measuring probe of the all-purpose stability analyzer turbiscantm is composed of a pulsed near-infrared light source (wavelength 880nm) and two synchronous detectors: the transmissive light detector is used to study low concentration (transparent) samples; The backscattered light detector is used to study samples with high concentration (opaque). Working principle of the instrument: the measuring probe moves up and down in the vertical direction of the sample cell within the range of 0-55mm to scan the whole sample. The data of transmitted light and backscattered light are collected every 40um, and the obtained figure can characterize the uniformity of sample concentration and particle size. The software sets the number of times to scan the sample, scans repeatedly, and superimposes the measured data to finally obtain a fingerprint that represents the stability or instability of the product.
