Calibration

The ToxCO®

is calibrated at 21°C (±4°C) before leaving Bedfont®.

The ToxCO® must be calibrated within 17-

25°C as this is the temperature at which Bedfont® recommend it is to be used.

It is recommended that the ToxCO® is calibrated every 6 months, however a calibration MUST be

performed within 12 months, using 50ppm CO calibration gas. Please refer to the ‘calibration procedure’

for more information.

Turn on the monitor by pressing the power button once.

Press the settings icon.

Press the cylinder icon once to proceed.
