Introduction:
YLN-50's colony counter is the automatic bacteria inspection instrument of one kind of digital display
type . It is composed by counter, probe, and count pond etc. It is designed by CMOS integrated circuit
and LED’s digital shows. The character is 13mm high and very distinct and bright. The special probe counts sensitively and accurately .
The comparison between bacterium illuminated by fluorescent lamp shows clearly and also is easy to be
observed in black count pond . This instrument can lighten the labor intensity and make the work with great efficiency , and is extensively used in the foodstuff , drink , drug , biological product , cosmetics , hygienic articles , drinking water , life foul water , industry waste water and clinical specimen inspection of bacteria number .
It is also the necessity of these unit below: grand epidemic prevention stations at all levels and the hygienic control inspection of environmental monitoring station, foodstuff the place, hospital , biological product institution, and the medicine inspection station, the business bureau , food products factory , drink factory , cosmetics factory , junior college and the scientific research unit laboratory .
Technology parameter
1 Counter capacity 0 ~'s 999 (note * )
2 Active display window character height 13mm
3 Lamp power 16W
4 Total power are smaller than 20W
5 Supply voltage 220V and 50Hz, Volume 255 * 180 * 110.
6 The magnification of magnifier connected with flectional arm are variable ,
7 The instrument weights 1.7Kg
8 Type A with function of phonetic count .
Use method
Put the culture dish on the white- light board , then open fluorescent lamp, using
probe by touching the dish to count . The number will display in LED screen;
Write the displayed number on the paper and turn off the electrical source quickly，
seeing the number return to zero from LED screen. Comparing the second count with
the first one, the same numbers can prove to be a accurate result.
( note * ) According to the bacteria count inspection procedure , when the bacteria
growth number is more than 300 in the culture dish , the sample should be diluted to
count again. ,so this instrument is ternary scale
