F4501 Safe-Air Testers are fitted with internal lithium rechargeable batteries and in addition also have a battery tray which accommodates 6 AA alkaline type batteries. In the event that the rechargeable batteries are not sufficiently recharged then you can continue to use the instrument with either the Alkaline AA batteries or a mains power supply. 

 

The unit features a colour touch screen, menu driven display, making air quality testing both easy and quick to 

complete, with a typical test taking about 18 minutes. 

 

The detection parameters of EN12021:2014 are met or exceeded during the automatically controlled test by the 

use of Draeger detector tubes to establish levels of carbon monoxide, carbon dioxide, and water. For oil the 

instrument can use either the Draeger Impactor or oil tube. The new Draeger Impactor has no glass or hazard 

components and can test for all known synthetic and mineral oils. An inbuilt electronic sensor measures oxygen 

content and the percentage concentration is displayed, whilst a push button allows the odour to be checked 

through a sintered exhaust port. 

 

At the end of each test results can be stored within the F4501’s memory (up to 20 tests can be stored) and then 

downloaded via the USB cable into PC compatible software which is available to download from Factair’s 

website. This software provides an easy way to retain and print test results. 

Factair’s quality accredited instrument workshop provides recalibration and servicing for the unit. In fact a 

testimony to the robustness and quality of Factair’s Safe-Air Testers is that units over 10 years old are still in daily
