Description
A Haemometer (sometimes spelled Hemometer) is a laboratory instrument used to measure the concentration of hemoglobin in blood. It is a common diagnostic tool in medical and research laboratories, especially useful in detecting anemia and monitoring hemoglobin levels.
Description:
A haemometer typically consists of:
A graduated glass comparator tube.
A reference color scale or comparator block.
Pipettes and reagents (usually N/10 HCl).
The principle is based on acid hematin method: blood is mixed with hydrochloric acid, which converts hemoglobin into brown-colored acid hematin. The solution is then diluted with water until its color matches the reference standard, and hemoglobin concentration is read directly from the graduated scale.
Key Features:
Accurate measurement of hemoglobin in g/dL.
Compact and easy to use.
Cost-effective diagnostic tool.
Commonly used in hospitals, pathology labs, research, and field testing.
Uses:
Detecting anemia.
Monitoring patients’ hemoglobin levels.
Routine blood examination in laboratories.
