Qiwei JL-2C Colony Counter rechargeable, voice count

The colony counter is a digital display semi-automatic bacteria testing 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 a black depth background, energy-saving ring lights are used for side lighting, and the colonies are clearly contrasted. 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 999, 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.
