Yokogawa Polymer Electrolyte pH Sensor PH4PT[Product print page]

Yokogawa Polymer Electrolyte pH Sensor PH4PT       

Yokogawa’s line of pH sensors has been strengthened by the inclusion of the polymer electrolyte pH sensor PH4P/PH4PT, HF-resistant pH sensor PH4F/PH4FT, pH sensor for chemical process PH4C /PH4CT, and pH sensor for fermentation PH4FE. Like the pH sensor series, the ORP sensor series is also offered as a complete lineup with the polymer electrolyte ORP sensor OR4P, ORP sensors for chemical process OR4C in addition to standard Ryton pH/ORP sensors. Yokogawa Polymer Electrolyte pH Sensor PH4PT

PH4/OR4 Sensor Series allows pH/ORP measurement under severe conditions, such as where the process fluid is heavily contaminated or contains sulfide. Yokogawa Polymer Electrolyte pH Sensor PH4PT

Yokogawa Polymer Electrolyte pH Sensor PH4PT

Polymer Electrolyte pH Sensor PH4P, PH4PT, OR4P
• Allows pH/ORP measurement under severe conditions, such as where the process fluid is heavily contaminated or contains sulfide ion.
• With polymer used as the inner solution, the liquid junction is large (around 1.0 mm), and there are 2 single pores, which prevent clogging.
• pH sensor with RTD (resistance temperature detector) PH4PT is also available.

HF-Resistant pH Sensor PH4F, PH4FT
• The special sensing membrane allows measurement of solutions or drainage containing hydrofluoric acid.
• With polymer used as the inner solution, the liquid junction is large (around 1.0 mm), and there are 2 single pores, which prevent clogging.
• pH sensor with RTD PH4FT is also available.

pH/ORP sensor for Chemical Process PH4C, PH4CT, OR4C
Yokogawa Polymer Electrolyte pH Sensor PH4PT

• Extremely long life span for pH measurement in electrolytic process.
• With the pressurized inner solution, a pressure holder is not needed.
• pH sensors with RTD, PH4CT is also available.
• The reference electrode is composed of silver ion trap which inhibits the generation of sulfide around the ceramic liquid junction.

pH sensor for Fermentation PH4FE
• Inner solution can be refilled.
• There are 3 of ceramic liquid junctions.
• The reference electrode is composed of silver ion trap which inhibits the generation of sulfide around the ceramic liquid junction.
