1
At room temperature (25 °C).
2
Response time at 25°C for a 90% signal change
3
Liquid flow through an ORBISPHERE 32001 flow chamber, with protection cap and no grille
4
These flow rates take into account the decomposition of ozone in the tubing between the line
and the flow chamber (theoretical flow rates in the absence of decomposition would be 10 times
less)
