Product overview

The SM-100 is a fetal monitor built around a 12.1-inch 1024 x 768 thin colour TFT screen that flips, so it can be read from either side of the bed. A concealed handle makes the unit easy to move about, and a dedicated probe holder keeps the transducer out of harm when it is not in use.

The ultrasound probe is a 1 MHz pulsed-wave Doppler with twelve crystals and a wide beam, which makes it more sensitive and widens the area from which a signal can be picked up. The 120-160 bpm normal range is marked on the trace, so the reader sees at a glance whether the rate sits inside it. Fetal movement can be shown and printed alongside the heart rate.

A large rechargeable lithium battery is standard, so a power cut does not interrupt a recording. Networking uses TCP/IP over cable or wirelessly with no loss of data, and the unit can be wall-mounted where floor space is short. The built-in thermal printer is 150 mm wide and prints across 112 mm. An NST automatic fetal assessment system is optional.
