The HM - 12V is a 12.1-inch multiparameter patient monitor designed for veterinary use. It offers comprehensive monitoring capabilities with six standard parameters: ECG, RESP, NIBP, SpO2, TEMP, and PR/HR. The monitor features advanced arrhythmia analysis, real-time ST segment monitoring, and efficient resistance to interference from defibrillators and electrosurgical devices. Its user-friendly interface, large storage capacity for trend data, and networking capabilities make it a versatile tool for critical care environments.

Buyer decision support
HQS lists four veterinary multiparameter monitors, all with ECG, respiration, NIBP, SpO2, temperature and pulse rate as standard. The HM-12V and HM-8V share one platform: 3- or 5-lead ECG with 13 arrhythmia types, ST-segment analysis and pacemaker detection, NIBP in manual, auto and STAT modes, networking and nurse call, and the same options (internal recorder, IBP, EtCO2, central monitoring, touch screen, VGA, neonate SpO2). The HM-12V has a 12.1-inch screen, a 4400 mAh battery and published IBP channels; the HM-8V has an 8-inch screen and a 2200 mAh battery. The HM-500V is a separate 12.1-inch platform with two temperature channels, 1 or 3 ECG waveforms, a 3-level alarm and central-station connection, 183 × 324 × 324 mm and 3.75 kg, with EtCO2 and a recorder as options. The HM-200V is the compact 7-inch unit: two temperature channels, optional CO2, about 4.5 hours on battery, 300 × 180 × 129 mm and 2.05 kg. Choose the HM-12V for the largest screen with IBP and arrhythmia analysis, the HM-8V for the same functions on a smaller screen, the HM-500V for a 12.1-inch unit with dual temperature, and the HM-200V where weight and space matter most.
