I. Overview XK97-A type colony counter is a digital display type semiautomatic bacteria test equipment. By the partial counter, exploration pens, cell count and other components. Counter using CMOS integrated circuit design and manufacturing. Deep black background style pool count, energy-saving fluorescent ring side exit lighting, clear contrast colonies. Inspection procedures in accordance with the provisions of the bacteria count, the instrument display is designed to triple digits, when the number of colonies growing in a petri dish more than 300, should the test sample dilution remaking, in order to ensure the accuracy of the count. This instrument can reduce the labor intensity of laboratory personnel, improve efficiency and quality of work. Our products are widely used in food, beverages, pharmaceuticals, biological products, health supplies, drinking water, industrial waste water, the number of bacteria in clinical samples tested. At all levels of health and epidemic prevention stations, environmental monitoring, food hygiene supervision and inspection, hospitals, Biological Products, Institute for Drug Control, food plants, of the plant and universities, research institutes laboratory essential equipment. Second, the main parameters * Counter capacity: 0-999 · the lamp power: 16W · Total power consumption: <20W · Power supply voltage: 220V ± 10%, 50Hz · volume: 280 × 230 × 90 · Weight: 2kg Third, use a. power, toggle switch count pool lights, the display shows "001", the pen inside the probe plug into the jack on the instrument, press the "Reset" button to zero the instrument into operation. b. into a petri dish for inspection. c. Use a pen to face probe points one by one all the colonies in a petri dish at the end. Each point should hear a "beep" sound only explanation is valid, or should the focus. At this point, point to the colonies are marked color display digital automatic accumulation. d. with a magnifying glass but check points without missing, counting already completed. Digital e. the display is the number of colonies within the dish. f. Remove the dish record figures. Press the "Reset" button, the display into the initial state. Fourth, note a. The instrument should be placed on a flat solid countertop use. b. When the colony count, do not be too inclined probe pen, when gently bounce down to have a sense of digital is entered. c. The instrument should be moisture, severe vibration, anti-direct sunlight, anti-acid erosion, dust cover after use should be added. d. Note to prevent bacterial contamination of cultures count pool. e. the instrument and probe pen can not be demolished. If you detect a problem, you should ask an experienced technical staff overhaul.
