General
The Model Q45P pH monitor provides an extremely versatile measurement
system for monitoring/recording of pH over the range of 0.00 to 14.00 pH.
The system operates on two AA batteries, and will run continuously for
approximately 240 hours.
Warning: If unit is to be stored for more that 6 months REMOVE the
batteries from the holder to avoid potential damage from battery leakage.
The Q45P displays pH, sensor temperature, sensor output millivolts, and output
mV signals on the secondary line of the custom display. The instrument may be
used with either the high performance Q25 series sensors or with combination-
style electrodes.
