Visão Geral
The T2PH, manufactured by Instrumentation Northwest, is no longer available. It was a two-parameter water quality sensor. The first parameter, temperature, was standard on all probes of this series and had a range of 0° to +50°C. The second parameter was ion-selective (i.e., pH). This sensor offered increased stability due to a patented reference electrode technology. The pH sensor used bulb technology.
