pH & ORP Sensor for Pulp & Paper


The Turtle Tough Pulp and Paper pH & ORP sensor is designed specifically for abrasive pulp slurries and high pressure, high-velocity flow paper processing lines. The unique solid state reference is designed specifically to resist dissolved chlorine gas. The ultra-tough glass resists high levels of abrasion and impact and allows for harsh cleaning.

The standard configuration is designed for immersion and submersible applications, while our VRS model is compatible with inline and sanitary (tri-clover) installations.

The RYTON body plastics combined with our advanced high capacity KYNAR reference is designed for chemical resistance, including chlorine and sulphides. Utilising our proprietary toughened glass the sensor is ideal for slurries and abrasive media as well as being capable of resisting acids or fluorides that may chemically attack the glass.

The 3/4" x 1" MNPT threaded connection allows for flexible immersion points into the process. With appropriate sealing onto an immersion rod, the sensor may also be fully submerged without the requirement of additional sealing (optional). Both body plastics and advanced reference system give this sensor an excellent operating range up to 105°C.

This sensor is ideal for any applications where process media containing free sulphide species such as hydrogen sulphide gas (H2S), hydrogen sulphide (HS-) or sulphide ions (S2-). Any measurement where aggressive chemical cleaning is needed to remove fouling or low maintenance operation is required with minimal cleaning and recalibration.

Digital Sensor Technology (-D)

This sensor is available with our digital smart sensor technology. This plug and play sensor has a quick connect fitting, eliminating the need for hard wiring to the analyser. Onboard sensor memory allows the storage of calibration data, analyser configurations and sensor service history. This allows the sensor to be conveniently maintained and calibrated off-site or in the laboratory and pre-programmed with calibration data and analyser configurations. This stored information automatically uploads to the analyser upon connection and eliminates the need for any interaction with the analyser, greatly simplifying the change-out of sensors. A service log stored on the sensors is ideal for maintenance and quality assurance records.
