The instrument is designed to test in accordance with the medical and surgical air parameters of HTM02-01 and the European Pharmacopoeia Directive. It also can test against the Pharmacopeia parameters for CO2, N2 and N20 supplies. 

 

For breathing-air systems the F4504 can test, both low and high pressure systems to EN12021 (in conjunction with the optional F3002 regulator for HP tests). 

 

The instrument has a built in electronic dewpoint meter, electrochemical oxygen cell and digital flowmeter which allows airflows of up to 600 l/min to be verified. The unit also has test ports calibrated for Draeger chemical reagent tubes / impactor to establish levels of oil, carbon monoxide, carbon dioxide, nitrous fumes, sulphur dioxide, hydrogen sulphide present in the air sample, as well as various easily oxidised compounds via a Polytest. 

 

The instrument is completely portable, operating from rechargeable lithium batteries which provide a prolonged operating life. The unit is supplied with a ‘laptop’ style carrying case which protects the unit during transport and has individual pockets for storing chemical reagent tubes, inlet adaptors, tube tip cutter and documentation. 

 

The F4504 will test systems between 2 bar and 10 bar and can be provided with an optional regulator and connecting hose to accept pressures up to 20 bar. 

 

At the end of each test the readings from each tube / impactor can be input into the instrument and it will then automatically calculate if the test was a pass or fail against the selected standard. 

 

The instrument is capable of retaining up to 20 previous tests and these are stored by the date and time when they were undertaken. They can be reviewed on screen and also downloaded to PC software via a USB cable provided with the unit. The software is available to download from Factair’s website and allows results to be easily retained and also test result certificates to be printed.
