CAUTION When there is H2O2 in the probe's environment, the probe must always be powered on. When powered on, the PEROXCAP sensor is heated, which permits using the probe in condensing H2O2 conditions, maintains measurement performance, and lengthens the probe's lifetime. When the probe is powered off, exposure to H2O2 condensation can cause the PEROXCAP sensor to fail within a day, and the sensor will not recover.

When the bio-decontamination process starts and the probe is exposed to H2O2, the probe's H2O2 concentration reading changes to > 0 ppm after approximately 20 ... 30 seconds. This time is included in the response time of the probe.
