A hemoglobinometer or haemoglobinometer (British English) is a medical device used to measure hemoglobin concentration in blood.

[4] It can operate by spectrophotometric measurement of hemoglobin concentration.

Portable hemoglobinometers provide easy and convenient measurement of hematological variables, especially in areas where clinic laboratories are unavailable.

[5] As per guidelines of National AIDS Control Organisation (NACO) for accurate results & mass screening,[citation needed] analysis using hemoglobinometer is a recommended method used for absorbance measurement of whole blood at Hb/HbO2/Isobestic point,[citation needed] based on microcuvette technology such as HemoCue 301[6] and Mokshit-Chanda-AM005A.
