Main features：
◎ ND-III Brookfield viscosity tester adopts the standard capillary viscometer stipulated in national standard in cooperation with laser ranging system controlled by microcomputer to test the flow of gelatin sol, calculate the flow time of sol, operate according to the way of Brookfield and automatically display the Brookfield viscosity value of tested sample. It’s featured by reliable verification process, accurate measurement, good reproducibility, strong visibility and easy operation.
◎ The design of display module of ND-III Brookfield viscosity tester starts with the need of large amount of information and high intelligentization to match with LCD with high resolution; users can enjoy intelligent operations according to the screen tips; Chinese character hint and quantitative index are provided for each operational process.
◎ The temperature range of ND-III Brookfield viscosity tester is arbitrarily adjustable from 20ºC to 70ºC, which has great superiority for researching and analyzing the quality control in the production process of gelatin.
◎ The design of ND-III Brookfield viscosity tester is in complete accordance with the provisions and requirements for instruments, appliances and determination methods in Brookfield viscosity determination methods stipulated in the standards such as Food Additive Gelatin of the PRC and Hard Capsule of Pharmaceutical Gelatin, etc. It can be widely applied to the production and test in the industries like medicine, chemical industry and gelatin to determine the Brookfield viscosity values of all kinds of gelatins.
◎ ND-III Brookfield viscosity tester can correct the non-linear error of jacket temperature automatically, monitor and realize fault diagnosis alarm automatically and track outrange protection in real time automatically.
◎ The capillary viscometer allocated for ND-III Brookfield viscosity tester has been strictly corrected in accordance with national standard before the delivery. Its error compensation factor has been written into the program of microcomputer and brought to the operation process of viscosity value.
◎Automatic monitoring of temperature rise process, automatic fault detection and automatic outrange alarm.
◎ The concentration value of tested substance is optional (6.67% and 12.5%); one-key conversion is realizable for the test of edible gelatin and industrial gelatin, the test precision is high; it has improved the phenomenon of inaccurate test for edible gelatin in original ND-II.
