ETCO2 Low Flow Side stream Module

ETCO2 MODULE

The Meditech MD-ET5 ,ETCO2 module

It is Low Flow Side stream Module. The new design is easier to match with monitor or anesthesia machine. The user just need to fix a 8-pin Lemo socket in the panel of the host, and connect the power of the host and dataline to an electrical outlet. This design will make maintenance much convenient. The MD-ET5 output parameters include real time CO2 concentration, respiration rate, end-tidal CO2, inspired CO2, The MD-ET5 module includes a miniature CO2 sensor, barometric pressure transducer, sampling flow control and a miniature low-power vacuum pump. The MD-ET5 can measure atmospheric pressure automatically, and has pressure compensated function. The host sends commands and receives waveform, breath parameters and command responses on two asynchronous serial data lines (TTL or RS232 level).

Features

Best performance price ratio around the world. The price is clearly lower than other similar module and the performance is better than them.

Better stability. Better design can wipe off the excursion from temperature, pressure and inconsistent component.

Provide 12inches Gas drier line. This Gas drier line can reuse for a one year.

Better communication interface. TTL or RS232 level can be choose
by customer.

Better policy of after service. Manufacturer promises that the module can be replaced by a new one if it is not damaged by manmade in one year.

Longer life. Using longlife IR source (100 thousand hours life).

The communication protocol of MD-ET3 is compatible with Respironics/Philips or CPT.
