ZH-200 hot sting instrument is the use of foot pain measurement method (hargreaves method) to identify freedom pain response to thermal stimuli. Microcomputer control, automatic determination of large / mouse foot in the free state of light and heat pain threshold stimulation time, easy to operate, and can automatically obtain measurement results, is an ideal instrument for experimental studies of pharmacological experiments analgesic drugs . Features: 1, can be observed simultaneously three rats or mice six toes thermal radiation stimulation experiments; 2, microcomputer control, F automatic determination of animal foot in the free state of light and heat pain threshold stimulation time; 3, timing accuracy, high precision; 4,5-100% of light intensity adjustment range can be precisely adjusted according to need; 5, for the protection of animals is not F burns, irradiation stop time can be set flexibly according to the irradiation intensity; 6, experimental platform transparency design, easy to operate and clean; 7, large-capacity information LCD display, dynamic real-time display of the experimental data for the current sample; 8, can automatically store 128 test records stored data automatically refresh, F can always check; 9 , beautiful and convenient touch membrane keypad, long life; 10, external thermal printer configured to provide real-time data printing capabilities; 11, with F PC machine data acquisition and analysis of communication capabilities. ZH-YLS-3E electronic instrument has a pressure tenderness accurate, easy to operate, data printing, computer connection function, with tenderness tweet audio amplifier circuit and large \ mouse fixed cylinder, research and teaching is a very practical one instrument, in actual use get expert professors praise. ZH-YLS-6B intelligent hot plate hot plate meter needle pain drug screening, detection of a common method, but also a method for distinguishing between the central nervous system can determine the mechanism of nerve pain did not shoot, There are a wide range of use in the past due to the temperature control is not in use strict timing inaccuracies and errors operational staff tend to make results specificity is not high, the instrument to solve the problem in the hot plate test, the trial and Practical experts praise intelligent hot plate apparatus also adds functionality and foot print \ hand press wired control function, can facilitate the completion of the mouse \ rat \ guinea pig testing laboratory, is ideal for teaching and research instrument. The instrument is simple to use, clear indicators of tissue damage smallest animal can be used repeatedly, pain response latency longer easy to observe little difference between the drug and measured, comparing the strength of the drug \ speed and duration Time \ while print out test data, is currently a hot plate at home and abroad a more advanced instrument.
