The Indigo80 handheld indicator is tested for compatibility with HPP270 probes that have firmware version 1.4.0 or newer. Probes with older firmware versions may have limited compatibility with the indicator.
| CAUTION
Do not use Indigo80 in low-power mode if you are logging data in a hydrogen peroxide environment. Using the low-power mode can power off HPP270 probes with a firmware version earlier than 1.4.0, resulting in condensation on the sensor and irreparable sensor damage. In all hydrogen peroxide measurements, ensure that the automatic power off function is disabled and there is enough battery charge to avoid an accidental power-off. Using an AC adapter to power Indigo80 during long-term measurements is highly recommended. |
