Corometrics 120 Series Features The Corometrics 120 monitor interactive training CD provides a step-by-step review of the disassembly and reassembly process. From the introduction of the parts down to the removal of the front bezel power switch, this interactive CD gives a comprehensive approach to servicing the 120 series. Comprehensive maternal/fetal monitor provides the ability to address every monitoring need for both the mother and the fetus Model 126: Dual ultrasound, FECG and Uterine Activity Model 128: Maternal NIBP and SpO2, in addition to Model 126 features Model 129: Maternal 3-lead selectable ECG in addition to Model 128 features Corometrics 120 Series Specifications Dimensions Height: 6.7”, 17 cm Width: 16.4”, 41.9 cm Depth: 17.3”, 43.9 cm Weight: 24 lbs (10.9 kg) approximate Ultrasound Mode Technique: pulse Doppler with autocorrelation processing Transducer type: 9-crystal Pulse reception frequency: 4 kHz single ultrasound mode, 2 kHz dual ultrasound mode Pulse duration: 92 µs Transmitter frequency: 1.151 MHz Intensity: <5mW/cm² Heart rate counting range: 50-210 BPM Leakage current: <10 µA at 120-240 VAC, isolated by transducer FECG Mode Technique: peak detecting, beat-to-beat cardiotachometer Heart rate counting range: 30-240 BPM Heart rate resolution: ±1BPM Artifact elimination: switch selectable, ±25 BPM artifact rejection Countable input signal range: 15 µV to 2mV peak-to-peak Offset voltage tolerance (differential): ±300 mVDC maximum Maximum common mode voltage: 20V peak-to-peak Preamplifier bandwidth: 1-100 Hz Common mode rejection: balanced > 120 dB at mains frequency, with patient cable, unbalanced = 5 kΩ RA or LA: > 110 dB at mains frequency Input equivalent noise: < 10µV peak-to-peak Input impedance: differential > 10 MΩ, common mode > 20MΩ Mains frequency rejection: > 40 dB Leakage current: < 60µA at 254 VAC, electrically isolated.
