Microprocessor Colony Counter

4-Digit LED Display:

Displays the current count in a 4-digit format, which allows it to show values from 0 to 9999.

Counting Range (0-9999):

The counter can count from 0 up to a maximum of 9999 colonies.

40 Memory Storage:

The device can store up to 40 previous counts, which is helpful in tracking multiple plates or experiments without losing data.

Hold and Count Correction:

Hold: Likely freezes the count at a specific value for review or confirmation.

Count Correction: Allows the user to make adjustments to the count if there is a mistake or if a plate was miscounted.

Data Retention After Power Failure:

The device includes a memory system that retains the data even in the event of a power loss. This prevents the loss of counts and allows for resuming operations without data loss.

This type of counter is commonly used in microbiology and laboratory environments for colony counting, where it helps to ensure accurate tracking of microbial growth and contamination. The memory function and power backup ensure reliable data storage, which is critical in experiments that may span long periods or involve numerous samples.
