Overview

     The HK-0404 automatic paraffin light stability tester complies with the requirements of the SH/T 0404 test method and is suitable for the determination of the light stability of food-grade paraffin, fully refined paraffin and semi-refined paraffin.

Functional features

1 The instrument constant temperature chamber is made of cast aluminum material with rounded corners inside, ensuring good air circulation

2 It is equipped with an internal voltage stabilizing power supply, ultraviolet high-pressure mercury lamp, and the ultraviolet illuminance is automatically controlled at (12.0±0.3) mW/cm², eliminating the need for manual adjustment

3 Touch screen operation, one-click start of the experiment, automatic constant temperature, automatic timing for 45 minutes and then stop irradiation, no need for manual supervision

4 The screen displays information such as the temperature of the constant temperature room, ultraviolet illuminance value, and time

5 The instrument is equipped with a UV-resistant glass observation window on top
