PH100 Panel Mount pH Analyzer
CE_Logo

The PH100 Panel Mount pH Analyzer is ideally suited for applications using simplified instrumentation such as small-scale wastewater treatment.

Based on the design concept of pH analyzers and Yokogawa's years of experience and achievement in the broad PA market, the PH100 provides a high degree of reliability with limited practical functions while retaining the capabilities of existing models. The converter packs simple functions in its compact housing, and also incorporates various self-diagnostics features for which the EXA Series enjoy a high reputation.

Dedicated pH sensors for the PH100 utilizes Yokogawa's field-proven detection system, and their miniaturized and lightweight design provides improved ease of use. To meet your application needs, an alternate lineup of pH sensors from Yokogawa (PH8EFP, PH8ERP, etc.) or other companies can be used in conjunction with the PH100 pH analyzer.

Combination holders for the PH100 is available in an adapter, submersion, or guide-pipe type depending on your application.
