Name: pH Sensor InPro4501/VP/PT100/SG
Brand: Mettler Toledo

Protected Against Breaking

The flat glass membrane of the InPro 4501 is protected by the PVDF body against breaking and is self-cleaning in flowing applications.

Eliminates Clogging & Resists Poisons

An open junction and Xerolyt® Extra polymer reference system provides resistance to poisoning, solvents, and strong acid or alkali conditions.

Accuracy at Low Temperatures

The InPro 4501 uses a special low-temperature glass that provides reliable pH measurement at low process temperatures.

Reliability to Ensure Uptime

The InPro 4501 provides the reliability you need to prevent interruption to your measurement. Its flat membrane is self-cleaning in flowing applications, and the PVDF body protects the sensor from physical impacts.

Easy to Install & Integrate

This pH sensor features a NPT thread process connection, allowing direct mounting into the process. This simplifies set-up and eliminates the need for extra housing costs. For submersion applications, the InDip is a suitable housing.

Low-Maintenance pH Probe

A solid polymer electrolyte requires no refilling or pressurizing, and is in direct contact with the process media via an open junction. This eliminates the possibility of junction clogging in contaminated media.

Solution Ground For Precise Measurement

This pH sensor has a solution ground that improves grounding and effectively eliminates the risk of electrostatic interference.
