Standard Warranty | 24 months from date of dispatch |
Intrinsic Safety Data
Maximum current in normal operation (pure O2) | 0.01 A |
Maximum o/c Voltage (10 to 100% O2) | 0.9 V |
Maximum s/c Current (10 to 100% O2) | 0.5 A |
Toxic gases at TLV levels will have no cross-sensitivity effect on CCR-Scientific oxygen sensors. At very high levels (i.e. percent levels), highly oxidising gases (e.g. ozone, chlorine) will interfere to the extent of their oxygen equivalent, but most other commonly occurring gases will have no effect.
Acid Gases
IMPORTANT NOTE: Acid gases such as CO2 and SO2 will be absorbed by the electrolyte and tend to increase the flux of oxygen to the electrode. This gives an enhanced oxygen signal of approximately 0.3% of signal per 1% CO2. CCR Scientific oxygen sensors are not suitable for continuous operation in concentrations of CO2 above 25%.
