Dwyer Instruments PHO-1 Specifications-Installation And Operating Instructions

The microprocessor based pH/ORP/Temperature Meter
offers quick response and high accuracy. Simultaneously mea-
sure and display pH from 0 to 14 pH (0 to 1999 mV) and tem-
peratures up to 200°F (100°C). Model PHO-1 meter features
manual or automatic temperature compensation, auto buffer
recognition, and data logging capabilities. The recording inter-
val can be defined by the user. The meter accepts any pH
electrode with a BNC connector. For additional convenience,
select model PHO-1K kit, which contains a meter, RS-232
cable, batteries, software, pH electrode, temperature probe,
gender changer, carrying case and manual.
