The 4OXV characteristics description, operation principle (OP02),
and product safety data sheet (PSDS 4) should be used together. The
data provided in this document is valid for 3 months from the date
of sensor manufacture under conditions of 20°C, 50% RH, and 1013
mBar. For guidance on sensor performance beyond these limits,
please refer to the 4OXIV characteristics description. Over time,
the output signal may drift below the lower limit. For guidance on
the safe use of the sensor, please refer to the operation principle
OP02.
Key features and advantages: • False alarm immunity • Improved
response time in extreme applications • Reliable fulfillment of
specified lifespan • Outstanding environmental performance
Typical applications include general, portable or fixed life
safety. The Toxicity Citizen is specifically designed for operation
in various environments and harsh conditions. However, it is
important to avoid exposure to high concentrations of solvent
vapors during storage, installation onto the instrument, and
operation. When using sensors with printed circuit boards (PCBs), a
degreasing agent should be used before installing the sensor. Do
not stick it directly onto or near the CiTiceL as the solvent may
cause the plastic to crack. Cross-sensitivity data: TLV levels of
toxic gases have no cross-sensitivity effect on the oxygen
CiTiceLs. At very high levels (i.e., percentage levels), highly
oxidizing gases (such as ozone, chlorine) can interfere with the
extent of their oxidation equivalents, but most other common gases
do not have an impact. Acidic gases: Important note: Acidic gases
such as CO2 and SO2 are absorbed by the electrolyte and tend to
increase the oxygen flow towards the electrodes. This gives an
approximate 0.3% enhancement of the oxygen signal for every 1% CO2
signal. Oxygen CiTiceLs are not suitable for continuous operation
when the CO2 concentration exceeds 25%.
