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 power, the counting chamber light turns on, display shows "000". Insert the probe pen into the instrument interface and press Reset to zero, ready for use.
2. Place the Petri dish into the counting chamber, use the probe pen to count each colony one by one. A beep sounds for valid counting, with colored marks and automatic number accumulation.
3. Check thoroughly with a magnifying glass to avoid missing colonies, then complete counting. Record data, take out the Petri dish and press Reset to restore standby state.

FAQ
Q: What are the requirements for pressing force and tapping rhythm when using the touch probe?
A: 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.
Q: What should be noted about the inclination angle of the probe?
A: Do not tilt the probe excessively when touching the petri dish, otherwise the probe may slip or lead to insensitive counting.
Q: How to prevent missed counts and repeated counts for dense colonies?
A: 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.
