Voice report colony counter XK98-A is a digital display semi-automatic bacteria inspection instrument. It is composed of counter, probe pen, counting pool and other parts. The counter is designed and manufactured by CMOS integrated circuit. In the counting pool with black depth background, energy-saving annular fluorescent lamps are used for side lighting, and the colony contrast is clear. According to the bacteria count test regulations, the instrument display is designed to be three digits. When the number of colonies in a petri dish exceeds 300, the test sample should be diluted and redone to ensure the accuracy of the count. This instrument can reduce the labor intensity of experimenters, improve work efficiency and work quality. The products are widely used in the detection of bacterial counts in food, beverages, pharmaceuticals, biological products, sanitary products, drinking water, industrial wastewater, and clinical specimens. It is a necessary instrument for health and epidemic prevention stations at all levels, environmental monitoring stations, food hygiene supervision and inspection institutes, hospitals, biological products institutes, drug inspection institutes, food factories, daily chemical factories, colleges and universities, and laboratories of scientific research units.

Turn on the power and turn on the lights of the counting pool. Throughout 001 inches; insert the probe plug into the instrument socket and press down. Reset and cycle through; set key to zero to make the instrument work.
Place in a Petri dish for testing.
C. Count the colonies one by one on the bottom of the Petri dish with a probe pen. Every point should be heard. Eucommia; Yingang's explanation is effective, otherwise it should be focused. At this point, the colony at that point is colored and the number is automatically incremented.
Check carefully with the magnifying glass to make sure nothing is missing and the count is complete.
The number on the display screen is the number of colonies in the Petri dish.
Record the number and remove the Petri dish. According to and other; reset and traverse; Key, the screen enters the initial state.
Precautions
The instrument should be used on a flat, firm surface.
Do not tilt the probe too much while counting colonies. Enter the number when the probe is pressed lightly until it pops.
The instrument should be protected from moisture, shock, direct sunlight, acid and alkali corrosion, and a dust cover should be added after use.
Take care to prevent bacterial culture from contaminating the counting tank.
Neither the instrument nor the probe can be disassembled at will. If a fault is found, it should be repaired by an experienced technician.
