Dissolved Liquid Cross Sensitivity

While the TecMicro is mono-scopic (low cross-sensitivity) to other gases, dissolved oxygen sensors can be sensitive to the following:

• Alcohols greater than 5%
• Hydrogen peroxide (H2O2) greater than 3%
• Sodium hypochlorite (NaClO, commercial bleach) greater than 3%
• Gaseous sulfur dioxide (SO2) or chlorine (CL2)

If the measurements are unstable and other troubleshooting procedures do not correct the problem, there may be interfering substances present in the solution.

There is no interference from the following:

• Carbon dioxide (CO2)
• Ammonia (NH3)
• pH, or any ionic species like sulfide (S2 -), sulfate (SO4-2), chloride (Cl-)
• Hydrogen sulfide (HS-)

Warranty

• 1 year. See CO2Meter terms and conditions.
