Yokogawa PH sensor FU20-VP-T1-NPT

Yokogawa PH sensor FU20-VP-T1-NPT

Yokogawa PH sensor FU20-VP-T1-NPT

All-in-One pH/ORP (REDOX) Sensor FU20/FU24/PH20

The PH20, FU20 and FU24 all-in-one sensors show how Yokogawa applies the motto "Simple is best" to sensor technology. These sensors feature four separate elements (pH, reference, temperature, ORP) allowing for simultaneous measurement of pH and ORP is possible with one sensor in a rugged Ryton or PVDF (FU20), Ryton (FU24) or PVDF (PH20). The integral or vario-pin cable comes number-coded cable along with the integral NPT threads on the sensor makes installation convenient. The Quick Release Adapters for the FU20 allow easy removal of the sensor for cleaning and calibration. 

Features and Benefits

Yokogawa PH sensor FU20-VP-T1-NPT
Avaiable as analog and digital SMART sensors (SENCOM)
Solid Platinum ORP/LE electrode for accurate simultaneous pH and ORP measurements. Integral Pt1000 element for accurate temperature measurements and enhanced pH accuracy
Double junction and long diffusional path for reference pollution/poisoning resistance. Saturated Ag/AgCl reference system with double junction combined with polymerized saturated KCl and ion-trap prolong the life of the reference probe even in chemically unfavorable environments.
Extended life time by large volume of polymerized electrolyte and porous PTFE diaphragm Cation Differentail reference system avaiable in the FU20 foor enlongated life Variopin connector or integrated cable options
Simple maintenance by comprehensive design
Versatile Direct in-line, immersion, off-line installation (flow fitting) and retractable Hot-tap (avaibale with use of the FU20 only)
Quick-Release adapter available for the FU20
Calibration certificate delivered with each sensor
Patented pressure compensation in the PH20 and FU24
Available in two versions, a robust dome shape model for applications with a limited amount of solids, and a flat surface model for applications in which solids are a considerable component.

Yokogawa PH sensor FU20-VP-T1-NPT

The FU20 combination sensor shows how Yokogawa applies the motto "Simply the best" to sensor technology. The wide body sensors (26 mm diameter) hold four separate elements in one unbreakable PPS40GF (RytonTM) or PVDF body. Installation is simple with the integrated industrial 3/4" tapered thread. The large volume gelled electrolyte and the double junction reference system slows down depletion and poisoning therefore extending the lifetime. The system is targeted at those applications where simplicity will result in accurate and reliable pH- or redox measurements. This means that in 90% of the know applications this sensor will be an excellent choice.
