Sensors – Four sensors are required to measure all of the water chemistry
parameters indicated above. Sensors are installed in the quatro cable bulkhead
ports indicated below to ensure proper function. If measurement of one or more
parameters is not required, the corresponding sensor(s) may be removed and
replaced with a sensor port plug. Accurate calculation of ammonia from
measured ammonium requires installed and properly calibrated pH and
temperature sensors.
