SGX-4OX electrochemical oxygen concentration gas sensor 4-in-1 detector
Product Description:
SGX-4OX electrochemical oxygen concentration gas sensor 4-in-1 detector
Features:
IMPORTANT NOTES · All performance is based on conditions at 20°C, 50% RH and 1 atm, using SGX recommended circuitry. · Sensor performance is temperature dependant; please contact SGX for temperature performance other than 20°C. · Do not solder to the connector pins as this may damage the sensor and thereby invalidate the warranty. · Details on recommended connector pins can be found in the Frequently Asked Questions within the Gas Sensor section of the SGX website.
ACID GASES Acid gases such as CO₂ and SO₂ will be absorbed by the electrolyte and tends to increase the flux of oxygen to the electrode. This gives an enhanced oxygen signal of approximately 0.3% of signal per 1% CO₂. The SGX4OX sensors are not suitable for continuous operation in concentrations of CO₂ above 25%. CROSS SENSITIVITY DATA Toxic gases at TLV levels will have no cross-sensitivity effect on SGX 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.
