Key features
The AQ2 300m Low Power is the same calibration-free pH and temperature sensor as the AQ2 300m, with ANB's new low power board. It draws 55 mA while measuring and only 5 mA idle at 12 V DC, so it runs much longer on batteries and suits sites with no power.
With ANB's battery housing and battery management system and the auto abrader, the sensor can measure for months without anyone attending to it. It calibrates itself in the water, has no glass and measures across 0.1 to 40 ppt salinity.
It ships with a 1 m cable. SubConn cables come in 1, 5, 10, 30 and 50 m lengths.
