TR-50S -type voice colony counter is a digital display-style semi-automatic bacteriological examination instruments. From counting the pool, explore pen, counters and digital displays and other components. Counter using CMOS integrated circuit technology design, counting fast, reliable, clear voice report number; digital display with LED digital display and intuitive; special probe pen, sensitive and accurate; deep pool of light and dark background style counts, no-glare lighting backlit shot down the side, so that colonies contrast clearly; bendable adjustable stand that can adjust the focal length of a magnifying glass and the illumination distance, more humanized, avoid small colony counting omission caused inaccurate test results.

         The number is calculated on a Petri dish of microorganisms is a very time-consuming task, this instrument is used to place the dish counting pool, its surface is pressure-sensitive components, special probe when marking pen on the surface will automatically start counting function. It has reduced the strength of the experimental operation, efficiency, ensure quality and other characteristics. Widely used in food, beverages, pharmaceuticals, biological products, cosmetics, health supplies, drinking water, sewage, industrial wastewater, the number of bacteria in clinical specimens testing and other fields. The health and epidemic prevention station, environmental monitoring, food hygiene supervision and inspection, hospitals, Biological Products, Institute for Drug Control, CCIB, food plants, beverage plants, cosmetics factory, daily chemical factories and universities, research institutes and laboratories at all levels essential instrument.
