CITREX H3 was developed in order to measure flow and various pressures and
thus calculate various ventilation parameters. CITREX H3is a compact, mobile and
easy-to-operate measuring instrument. The device was developed in order to cali-
brate gas flows and pressures by simple means. With the oxygen option it is possible
to measure oxygen concentrations.
The descriptions and instructions in this manual refer to the product CITREX H3.

This product is intended for testing and calibration purposes on medical devices
orsystems thatgenerate gas flows or gas pressures. That includes ventilators and
anaesthetic equipment. The user of the device has received training on how to use
medical equipment and can perform repairs, maintenance and servicing on medical
devices. CITREX H3 can be used in hospitals, in clinics, at device manufacturers or
at independent service companies that perform repairs or servicing operations on
medical devices.
CITREX H3is intended for use in a laboratory environment. It may only be used out-
side the nursing sector. It must not be used directly on patients or devices that are
connected to patients. The measuring instrument CITREX H3is intended for over-
the-counter sale.
With CITREXH3 you have the solution for measurements in the following areas:
• Flow
• Pressure
• Volume
• Ambient pressure
• Temperature
In addition, various ventilation parameters can be measured:
• Ventilation rate
• Time
• Ratio
• Tidal volume
• Minute volume
• Peak flow
• Pressure
• Trigger
CITREX H3 is a measuring instrument for checking and calibrating
ventilators and anaesthetic equipment. It must not be used for patient
monitoring. During patient treatment by the ventilator it is not allowed
to connect to CITREX H3.
It is not allowed to measure liquids with CITREXH3.
