Digital Leucocyte Counter (10-type Differential Count)

Leucocyte counting is essential to detect abnormalities consistent with infectious or haematological processes. This digital counter streamlines the leucocyte differential via keys dedicated to 10 cellular subtypes plus a totaliser, expediting work in clinical laboratories, teaching and quality control.

Each key press adds one unit to the display of the corresponding subtype and to the overall total. It includes a reset (zeroing) function and automatic percentage calculation for each population relative to the total, reducing transcription errors and saving time versus manual calculations.

Typical assignable subtypes

Basophils, eosinophils, monocytes, lymphocytes, mature neutrophils (segmented) and immature forms (band), as well as granulocytic precursors such as promyelocytes, myelocytes and metamyelocytes, plus an additional configurable channel (e.g., blasts). The exact distribution can be adapted to laboratory protocols.

Main features

• 10 differential count keys with individual and total displays.
• Immediate calculation of percentages by subtype relative to the recorded total.
• Reset (zeroing) function to start new differentials with a single touch.
• Count range per channel: 0–99 units.
• Design suitable for continuous use in haematology routines and training.

Technical data

• Operating modes: differential counting by channel and total count.
• Result presentation: absolute count per channel and percentage of total.
• Power supply: 220 V – 50 Hz.

Applications and benefits

• Support for manual blood smear assessments in laboratories performing microscope-based differentials.
• Standardises data recording and minimises manual calculations, improving traceability.
• Useful in teaching to understand the relative distribution of leucocyte lineages.

Note: Channel names can follow internal laboratory procedures to match your reporting scheme (e.g., separation of segmented/band neutrophils, inclusion of granulocytic precursors or blasts as required).
