Yokogawa HF-Resistant pH Sensor PH4F[Product print page]

Yokogawa HF-Resistant pH Sensor PH4F       

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 HF-Resistant pH Sensor PH4F

PH4/OR4 Sensor Series allows pH/ORP measurement under severe conditions, such as where the process fluid is heavily contaminated or contains sulfide. Yokogawa HF-Resistant pH Sensor PH4F

Yokogawa HF-Resistant pH Sensor PH4F

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 HF-Resistant pH Sensor PH4F

• 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.
