CAUTION
The probe contains sensitive visual components. Please handle the probe
with care.
Strong vibrations alter the factory calibration. Checking of readings in fresh
air 350 to 450 ppm CO2 (urban air up to 700 ppm CO2).
Avoid dew on the probe, otherwise long-term stability will be impaired. If
there is dew on the probe, this can lead to higher CO2 readings.
If the ambient temperature changes (change of measuring location, e.g.
indoors to outdoors or vice versa), the probe requires an acclimatization
phase of a few minutes.
After the instrument is switched on, there is a sensor warm-up phase of
approx. 30 s.
The CO2 concentration in the sensor requires approx. 60 s to acclimatize to
the environment. Gently waving the probe reduces the acclimatization time.
Keep the probe as far away from your body as possible. This avoids any
influences due to the CO2 content of the air you breathe.

DANGER
Risk of death!
Carbon monoxide is a colourless, odourless and tasteless gas. High
concentrations can cause death.
- Do not use the CO probe as a monitoring instrument for personal safety.

6Maintenance
6.1 Maintaining the probes
6.1.1 Cleaning the instrument
Do not use any aggressive cleaning agents or solvents; instead use
mild household cleaning agents or soapy water.
Always keep the connections clean and free from grease and other
deposits.
Clean the instrument and the connections with a damp cloth and dry them off.

6.1.2 Calibration
The probes are supplied with a factory calibration protocol as standard.
Recalibration of the probes once every 12 months is recommended in
many applications.
This can be carried out by Testo Industrial Services (TIS) or other
certified service providers with the aid of easy-to-use service software.
Please contact Testo for further information.
7Technical data
Adjustment conditions for flow probes:
Adjustment in free jet Ø 350 mm, reference pressure 1013 hPa,
based on testo reference Laser Doppler Anemometer (LDA).
Note for flow probes:
Low flow velocities may result in greater measurement uncertainties
during humidity and temperature measurement!
Note for humidity probes:
Please do not use the humidity probes in condensing atmospheres.
For continuous use in high-humidity ranges
