Yokogawa Widebody type pH/ORP Sensor FU20-10-T1-NPT/BSS

A family of the wide body sensor is available for application in a wide variety of processes. The sensors share the same
valuable features:
? Long life saturated Ag/AgCl reference system.
? PTFE reference diaphragm to prevent fouling and reduced measurement error.
? Double junction combined with ion-trap to prolong the life of the reference probe, even in chemically unfavorable environments.
? Integral Pt1000 element for accurate temperature measurements.
? Platinum ORP/LE electrode for accurate simultaneous pH and ORP measurements.
? Polymerized electrolyte to extend the sensors life time.
? Versatile in-line, immersion or off-line installation.
? Any angle of installation including upside down mounting for all VP/VS models 
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 measuring elements in one unbreakable and chemical resistant PPS 40GF body. Installation is simple with the integrated industrial 3/4”
tapered thread. Temperature fluctuations are compensated to extend the sensor life. The FU20 is targeted at those applications where simplicity will result in accurate and reliable pH- or redox measurements. This means that in 90% of the known applications, this sensor will be an excellent choice.
In general purpose applications running at constant pressure and temperature the FU20 sensor has proven it use for years.
