Mainstream EtCO2 Sensor

Model: ET100

Product Description

Product Introduction

The ET100 Sensor is a highly integrated mainstream CO2 Sensor which developed by RSD medical, who had tens of years IR measurement instrument development experience. It’s the one-step capnography solutionfor patient monitoring system. Within a very compact size, it provides measurement of End-Tidal Carbon Dioxide(ETCO2), respiration rate, capnogram, which can cover most of requirement from the patient monitoring system. With a very simple RS232 interface and industry compatible protocol, it’s fairly easy to connect ET100 to any patient monitoring system and other medical treatment system where CO2 sensor is needed.

With the stability, flexibility and easy to use as the built in essence, ET100 is your ideal choice for your capnography subsystem.
