Hangzhou Qiwei Instrument Co., Ltd. is one of the leading manufacturers and suppliers of Voice Reporting Colony Counter in China. With a professional production team, we are able to meet the needs of the majority of our customers. Welcome to wholesale bulk Voice Reporting Colony Counter in stock here from our factory. We also accept customized orders.
Developed for routine microbial colony enumeration in lab settings, the XK98-A semi-automatic colony counter features voice prompt function. It integrates real-time digital readout, touch trigger probe pen, visual marking and automatic value accumulation to streamline counting operations for petri dishes.
Unlike conventional colony counters that only show readings on screen, this XK98-A model emits an audio prompt each time a valid colony is marked. This lets technicians keep their focus on the petri dish instead of constantly glancing back and forth at the display. Every valid count is tallied automatically, and the probe leaves coloured marks on the plate surface to avoid repeated counting.
With a counting range from 0 to 999, the XK98-A fits routine microbiology testing in research labs, food factories, pharmaceutical plants, biological product workshops and environmental monitoring sites. It serves as an auxiliary tool for colony counting, rather than an instrument for automatic microbe identification or result analysis.
product key technologies
Introduction
The XK98-A Voice Reporting Colony Counter is a semi-automatic digital bacterial counter, consisting of a main unit, detection probe and counting compartment. Powered by mature CMOS circuits, it features circular energy-saving side lights inside the dark compartment, delivering clear views of bacterial colonies.
Compliant with industry testing standards, it adopts a three-digit display. When colonies on one culture plate exceed 300, dilute the sample and retest for precise results. It cuts down lab workload and raises testing efficiency, widely applied to bacterial detection for food, beverages, pharmaceuticals and biological products.
This device is a must-have for epidemic prevention stations, environmental monitoring centers, food inspection bodies, hospitals, research labs, pharmaceutical testing institutions, food factories and academic research facilities.
Operational Approach
1. Switch on the instrument. The counting chamber light turns on and the display shows "000". Insert the probe pen into the designated interface.
2. Press Reset to ensure the counter starts from zero.
3. Place the prepared Petri dish in the counting chamber. Touch each visible colony with the probe pen. Confirm the audible prompt and check that the displayed count increases.
4. Use the colored marks, magnifying glass, or partition-counting method to organize the inspection. After completing the count, record the result, remove the Petri dish, and press Reset before the next sample.
Application
Food and Beverage Microbiology Testing
The XK98-A can be used to help with habit settlement enumeration on ready culture plates in food inspection laboratories and production quality control departments. When providers need to process multiple samples in a structured workflow, automated accumulation and Audible confirmation are useful.
Pharmaceutical and Biotechnology Quality Control
The counter may be used during regular bacterial monitoring and culture-based testing in pharmaceutical testing facilities and biotechnology labs. Mechanical colony counting is supported by the instrument, but it does not replace laboratory quality procedures or validated microbiological methods.
Environmental and Water Quality Monitoring
The XK98-A can be used to record noticeable colonies on prepared culture plates in environmental monitoring centers and water testing labs. The appropriate testing protocol should be followed for sample dilution, incubation, and result interpretation.
Hospitals, Research Institutes, and Educational Laboratories
The counter can be used to teach microbiology, conduct research, and perform regular laboratory tests where necessary, such as counting colonies.

FAQ
1. What are the requirements for pressing force and tapping rhythm when using the touch probe?
Tap colonies gently and moderately with the touch probe. Do not move the probe away until you hear the beep or voice prompt and confirm the number on the screen increases. Avoid counting errors caused by overly fast operations.
2. What should be noted about the inclination angle of the probe?
Do not tilt the probe excessively when touching the petri dish, otherwise the probe may slip or lead to insensitive counting.
3. How to prevent missed counts and repeated counts for dense colonies?
For dense colonies, you can mark the bottom of the petri dish with a marker pen, or use the partition function of the instrument. This helps avoid repeated counting and missing colonies.
4. Can the counting result be reset for a new sample?
Yes. Press the Reset control to return the display to zero before beginning a new counting task.
5. What is the maximum counting capacity?
The XK98-A has a digital counting capacity of 0–999. Follow the applicable laboratory method for sample dilution and countable colony ranges.
