It is a myth that interchangeable sensors mean you don’t need to replace sensors as they don’t die. The reality is that interchangeable sensors do still have a lifetime and will need changing:
Sensors also have a much shorter shelf life if not installed in the instrument as they require small amounts of charge to keep them primed.
Using interchangeable sensors, you may not see the sensor die off as you are changing them out regularly, however typically with interchangeable sensors you are paying a premium for the sensor over a traditional calibration and periodic replacement.
In most analysers typical life span of a sensor is:
SF6 4-5 years in analyser
H2O 4-5 years in analyser
SO2 2 years in analyser, typically 6 months on shelf
HF 2 years in analyser, typically 2 months on shelf
CO 2 years in analyser, typically 6 months on shelf
H2S 2 years in analyser, typically 6 months on shelf
The EMT Way:
EMT analysers are based on Infra-Red (IR) sensing technology.
Our latest Zerowaste Eco+ 4in1 SF6 and SF6 alternative analyser has the latest version of this sensing platform allowing us to achieve the following sensor life:
SF6 Lifetime: never needs changing
H2O Lifetime: never needs changing
SO2 5 years
HF Lifetime: never needs changing
CO 5 years
H2S 5 years
