Why is the NX1 CiTiceL better than the 3NF/F for automotive applications?
The NX1 Nitric oxide CiTiceL is recommended for use in automotive applications, having been specifically designed to withstand the rigors of a garage environment. It shows little or no cross-sensitivity to the gases typically found in a vehicle exhaust gas sample and has an extremely fast response time (meets BAR 97 requirement). The standard 3NF/F CiTiceL has been designed for monitoring nitric oxide in flue (stack) gas emissions and would not meet the BAR 97 response time requirement.
