GA-1 CO2 ANALYZER

MONITORS BREATH CO2 – Now a CO2 signal can be added to the ECG-HRV, respiration belt, and EMG of other GP units. This miniature breath gas analyzer includes a PPG pulse sensor. It displays NTCO2, CO2 wave, breath rate, HR, BVP, and HRV. Software is included and it’s signals can be added to other physiology signals from GP units or used alone.

THE TECHNOLOGY – Physiocom Design has designed and manufactured CO2 units for over twenty years. This fifth generation design has very stable calibration. The reading delay is small and end tidal CO2 peak is more accurate than other equipment. It comes with a water trap that is high capacity and can be renewed many times.

SOFTWARE – General purpose signal monitoring and recording applications are included. The included software is supported on Windows 10 and 11. This unit runs stand alone or with the GP-4, GP-8, or GP-12. This software was completely updated in 2023 and includes heart lung animation. The lungs change size and color with EtCO2 and the heart with HR and HRV score.

LOW COST USE – Parts that may need eventual replacement are all plug in. The battery, air pump, CO2 sensor can be replaced at low cost. The software can tell if a part needs to be replaced.

GP-12e PHYSIOAMP

MONITORS 12 CHANNELS – Four input channels are microvolt level with selectable gain and bandwidth for EMG, EEG and ECG. Four channels are temperature, respiration, or other high level sensors. Four channels are for GSR SR/SC. One channel is for PPG optical sensors to measure HR and BVP.

SOFTWARE – General purpose signal monitoring and recording applications are included. The 2023 updated software is supported on Windows 10 and 11. Third party software is available from several suppliers. We provide drivers and support for software developers. GP-12 is compatible with software developed for older I-330-C2+ devices.

NO BATTERIES – Power is supplied from USB by an isolation module. This reduces down-time and service problems. This radio frequency isolated power and data is superior to optical.

RELIABLE CABLES- Medical standard 1.5mm pin to snap leads are used for electrode connections and are available from many suppliers.

NEW TECHNOLOGY – It gives you cleaner signals, more reliability, and lower cost in a compact, rugged enclosure. New advanced chips provide 16 bit signal resolution.

COMPACT DESIGN – A general purpose physiological signal monitor in a case the size of 2 packs of playing cards. Add a small computer and you have a system in your pocket.

CONNECTION TEST – A built-in test monitors electrode connections and shows ohm values.

ADAPTABLE – A digital input connects optional accelerometer or compass modules for virtual reality applications. This input is also used for event markers from other equipment.

GP-8e+ PHYSIOAMP

MONITOR SIX CHANNELS – Two inputs channels are microvolt level with select-able gain and bandwidth for EMG or EEG or ECG. Two channels are temperature, respiration, or other high level sensors. One channel for skin resistance, One channel for PPG to measure HR and BVP.

SOFTWARE – General purpose signal monitoring and recording applications are included. The 2023 updated software is supported on Windows 10 and 11 Third party software is available from several suppliers. We provide drivers and support for software developers.

COMPACT DESIGN – A general purpose physiological signal monitor in a case the size of a pack of playing cards. Add a small computer and you have a system in your pocket.

NEW TECHNOLOGY – This gives cleaner signals, more reliability, and lower cost in a compact, rugged enclosure. The encoder provides 14 bit signal resolution.

NO BATTERIES – Power is supplied from the USB cable by a radio frequency isolation module. This provides complete electrical isolation from the computer.

CONNECTION TEST – A built-in test monitors electrode connections.

ADAPTABLE – A digital input to connect optional accelerometer or external event signals.

RELIABLE CABLES – Medical standard 1.5mm pin to snap leads are used for electrode connections and are available from many suppliers.

GP-4BT

MONITORS FIVE CHANNELS – One input channel is microvolt level for EMG, EEG or ECG. Two channels are temperature or respiration sensors. One channel is skin resistance. One channel is for optical sensors, PPG for heart rate and BVP.

RECHARGABLE BATTERIES – Wireless charging like a phone. The replaceable 18650 Lithium battery powers the unit for over 8 hours. It is common and easily changed.

COMPACT DESIGN – A general purpose physiological signal monitor in a case the size of a pack of playing cards. Add a small computer and you have a system in your pocket. Includes an accelerometer and magnetic compass in the GP-4BT send signals that can be used for animation and body motion work.
