We support and service your measurement equipment through its entire life-cycle, from installation to preventive maintenance and calibration to equipment repair.
The InPro 2000 and InPro 2000i by METTLER TOLEDO are refillable and pressurizable pH sensors that offer distinct features to ensure pH measurement accuracy and reliability. Designed with a domed-glass, pH-sensitive membrane and automatic temperature compensation, the InPro 2000 pH sensor family is proven to succeed in extreme environments. Applications for the InPro 2000 and InPro 2000i range from biotech processes requiring in-situ sterilization to dirty industrial chemical processing.
Ensuring reliable results over a long lifetime, the InPro 2000 pH sensor uses a refillable electrolyte, which can provide significant savings, compared with non-refillable sensors.
The flowing liquid electrolyte is one of many distinct features the InPro 2000 offers to ensure a fast response, consistent and accurate pH measurement, and long-term reliability.
The InPro 2000 uses a pressurizable reference electrolyte to ensure low maintenance in harsh applications. The sensor is also ATEX and FM certified for installation in hazardous areas.
The InPro 2000i uses Intelligent Sensor Management (ISM) advanced predictive diagnostics to help plan calibration and maintenance scheduling of your pH and redox sensor for only when it is needed.
There are three liquid electrolytes available for the InPro 2000. The 3M KCl, Viscolyt™ and Friscolyt™ options help tailor the InPro 2000 and InPro 2000i pH sensor to your process media needs.
The InPro 2000 and InPro 2000i offer various sensor lengths to meet your specific installation requirements. Available sensor lengths include 120mm, 150mm, 250mm and 450mm.
The InPro 2000i digital ISM pH sensor is a combined pH and ORP (redox) sensor. This is made possible by the platinum solution ground, which comes standard with all InPro ISM sensors.
The InPro 2000 is a family of refillable pH sensors with an integrated temperature sensor designed for demanding applications to ensure accurate measurements. With an extensive operational lifetime, this sensor is proven to be reliable and can provide significant savings when properly maintained. With its domed-glass, pH sensitive membrane and automatic temperature compensation features, the InPro 2000 is able to succeed in extreme environments. The InPro 2000i is a digital pH sensor that uses ISM advanced diagnostics that adapt to your process and help plan for maintenance.
The difference between the InPro 2000 and the InPro 2000i is that the InPro 2000 uses analog technology while the InPro 2000i is an ISM digital pH sensor. ISM advanced predictive diagnostics are available on the InPro 2000i digital sensor. The InPro 2000i also allows for the measurement of ORP.
To cope optimally with the conditions prevailing in different types of chemical processes, a variety of electrolytes are available with the InPro 2000 and InPro 2000i. The 3M KCl is a classic electrolyte offering high flow for improved junction cleaning, Viscolyt™ has limited flow for reduced maintenance needs, and Friscolyt™ is ideal for process media with high protein or organic solvent content, and in low temperatures.
The InPro 2000i digital pH sensor has the ability to measure ORP (oxidation-reduction potential, or redox) in addition to pH. ORP is an important parameter to describe the electrochemical condition in a process. It is often used in chemical processes and is a common measurement in biotech applications as well.
The InPro 2000i gives access to all ISM features when integrated with the appropriate transmitter. These include the Time to Maintenance (TTM) indicator, which gives a predictive indication of when electrolyte will need refilled and the Adaptive Calibration Timer (ACT), which uses process conditions to diagnose when a calibration will be needed. The InPro 2000i also has Plug and Measure technology, which allows you to hot-swap a sensor by calibrating it away from the process and then quickly implement it into the process without the need for calibration at the measurement point.
