About The Monitor

The new F8004 multi-air tester is ideal for both medical and dental air testing for a wide range of gasses and contaminants all within one device. Designed to provide a quick and easy method for carrying out accurate testing of breathing-air supplies, the Multi-Air Tester is the latest addition to the Medi-Gas Check range of portable medical gas analysers for pipelines.

With robust casing and a 7” touchscreen colour display, the F8004 has been designed to test against a range of international standards including EU Pharmacopoeia, HTM 02-01, HTM2022 Supplement 1. The instrument can also test breathing-air supplies to EN 12021, CGA G-7.1-2011 grade D and AS-NZS 1715:2009.

The F8004 incorporates electronic sensors for to measure gas quality and contaminants and a PID sensor to test for volatile organic compounds (VOCs). A sample test point for Dräger Impactors is used to test for the presence of oil aerosols, whilst an electronic dewpoint meter measures moisture content.

The F8004 Multi-Air Tester is Factair’s most advanced portable medical and breathing-air quality monitoring instrument.

Modes and Results

The F8004 has 2 monitoring modes; individual site tests or continuous monitoring. The Multi-Air Tester can store up to 21 individual tests in the instrument’s memory which can be ‘tagged’ with the name/location and viewed via the full-colour touchscreen.

Alternatively, the F8004 can be set up to continuously monitor a point and store up to 3 months’ worth of data on the device. All results can be downloaded to a PC using the FREE software provided with the instrument.


Fully portable, the F8004 can has internal rechargeable batteries that last up to 3 hours for one-off tests, but also has a mains power supply allowing the instrument to be set up and left for up to 3 months at a time for continuous live sensor readings and logging.
