Enhanced Visibility and Precision

This digital colony counter features a white LED ring that illuminates the working area, ensuring clear visibility of colonies. With an adjustable lens magnification up to 3x and a large 75 mm diameter lens, users can closely examine and accurately count colonies, even those that are faint or small.

User-Friendly Digital Controls

Equipped with a pressure sensor touch pen and a digital display, this colony counter simplifies the counting process. Each colony count is instantly registered, with an audible buzzer providing confirmation. The manual touch operation combines user control with the accuracy of digital technology, supporting up to 9999 counts per specimen.

Reliable Performance in Laboratory Settings

Constructed with a robust ABS plastic casing and mounted securely on the tabletop, the device is built for repeated laboratory use. It operates on 230 V AC, 50 Hz, with low power consumption (5 W), and accommodates standard petri dishes up to 90 mm. Its compact size and 2.5 kg weight make it easy to position and relocate as needed.

FAQs of Digital Colony Counter:

Q: How does the pressure sensor touch pen work for colony counting?

A: The pressure sensor touch pen acts as an intuitive counting tool. When gently pressed against a colony on the petri dish, it registers a count that is immediately displayed on the digital screen, accompanied by a buzzer sound for confirmation.

Q: What benefits does the white LED ring illumination provide?

A: The white LED ring offers bright, even illumination to the entire petri dish area, significantly improving colony visibility and reducing eye strain, which results in higher counting accuracy and ease of use, especially in low-light conditions.

Q: Where is this digital colony counter typically used?

A: This equipment is primarily used in laboratories, including microbiology, pharmaceutical, clinical, and quality control settings, where precise colony counts are essential for microbial analysis and research.

Q: What is the process for counting colonies using this device?

A: Place a standard 90 mm petri dish on the unit, adjust the lens for optimal magnification, and use the touch pen to count colonies manually. Each touch registers a digital count, and the buzzer provides audible feedback. The result is displayed instantly.

Q: When should calibration or maintenance be performed on the unit?

A: Routine visual inspection and gentle cleaning of the lens and sensor pen are recommended regularly. Calibration checks should be carried out periodically or whenever accuracy is in question to ensure precise counting results.

Q: What is the maximum number of colonies this counter can register in one session?

A: The digital counter can accurately register up to 9,999 colonies per petri dish, making it suitable for a wide range of microbial assays.

Q: What are the advantages of the devices digital control mode and manual touch interface?

A: The digital control mode combined with the manual touch interface offers users full control over the counting process, minimizing human error and ensuring that each count is both deliberate and accurately recorded.
