Never as in these pandemic days, due to COVID19, the human being wants to know the oxygen amount
presents both in his body and in the surrounding environment, also because due to the equipment use that
produces ozone, oxygen becomes more and more lacking.

BEINAT S.r.l. with the prestige that has distinguished it for over forty years and the concept of "equipment
fitness" has built a sophisticated portable oxygen detector, with a rechargeable battery also via PC.

Gas concentration reader
The technology of this instrument and its precision in detecting this gas are due to an optical fluorescence
sensor, the response of which is managed by a microcontroller.
The percentage of oxygen present in the air is constantly shown through its display. The detector promptly
informs the danger threshold, due to deficiency or excess of oxygen, in the following percentages:
Excess 23.5%, indicated on the display in red
Typical oxygen in air 20.9%, indicated on the display in green color
Deficiency 18.5%, indicated on the display in red

Reading from 0% to 25%. Resolution 0.1%

The NASE25_O2reading can also be performed in a low lighted environment as the display is backlit.
The charge and discharge of the battery is controlled by the microprocessor reporting on the display the
percentage of charge
The brand products BEINAT S.r.L. comply with European Rules BATTERIES AND ACCUMULATORS 2006/66/EC RAEE 2003/

Cleaning Never clean the device with chemical products. If necessary, wash with a moist cloth.
For your safety

Function of the OXYGEN Detector
Press the button to turn the instrument on or off, hold it down for 5 seconds.
Detection
Turning on you will notice on the Display the beginning of a COUNT DOWN which will last about 15 seconds
(stabilization) after which the instrument will be ready to detect.
Hold the detector in your hand, at an average height above the ground to detect the concentration of
OXYGEN that is found in the air.
EXCESS ALARM
If the instrument detects an Excess Oxygen, the percentage will appear on the display together with an
intermittent sound more or less fast depending on the extent of the detection.
Together with the sound, the Display will light RED.
DEFICIENCY ALARM
If the instrument detects an oxygen deficiency, the percentage will appear on the display together with an
intermittent sound more or less fast depending on the extent of the detection.
Together with the sound, the Display will light RED.
Backlight
Pressing the button turns on the green backlight with a duration of 5 seconds.
Display of the battery charge status
The battery figure is shown on the display.
When it is loaded the figure is all black,
discharging becomes white, when flashing it is discharged.
Note: The appliance provides for an automatic shutdown after 10 minutes of inactivity (no button press
and no detection).
