The HemoGuard Hemoglobin Testing Kit is intended for the quantitative determination of hemoglobin (Hb) in capillary and venous human whole blood. The easy to operate system consists of a portable meter that analyzes the intensity and color of light reflected from the reagent area of a test strip, ensuring quick and accurate results. The HemoGuard Hemoglobin Testing System provides results in less than 15 seconds and requires only a single drop of whole blood. The meter can store up to 1,000 results and records can be transferred to a computer for further analysis using the USB port. The meter can be operated by 3 AAA (1.5V) batteries(INCLUDED) or an optional AC adapter.
