Surveyor S4 Mobile Monitor

Easy to handle and lightweight, the innovative Surveyor S4 Mobile Monitor can be comfortably worn by patients while in ambulatory settings.


It supports multiple patient types and acuities with three-, five- and twelve-lead cables for various levels of monitoring. The Surveyor S4 displays continuous SpO2 (%), plethysmogram and pulse rate, helping you conveniently check your patients locally or from the Surveyor Central Station. Surveyor S4 enables you to leverage past capital investments by using your facility's existing wireless network infrastructure. Its bright, 4-inch LCD and easily selectable vibration response buttons can be used with bare or gloved hands. Check individual ECG electrodes using the hook-up screen, view real-time ECG waveforms and feel confident with smart features such as display timeout and nurse call.
