Using the same potentiometric measurement principle as traditional glass electrodes, the InPro X1 achieves accurate, consistent pH readings across the entire pH range of 0 to 14. Its innovative design eliminates the inner liquid buffer found in glass sensors, drastically reducing drift, especially at high temperatures, and extending calibration intervals by up to 100%.
The InPro X1 ensures consistent product quality through process automation enabled by accurate and continuous in-line pH measurement, ensuring uniform taste and texture in food and beverages.
The unbreakable InPro X1 enables contamination-free production and HACCP compliance, significantly reducing the likelihood of product recalls and protecting consumers from injury.
InPro X1’s hygienic design and Food Contact-certified materials simplify compliance with food safety regulations, lowering audit process efforts.
InPro X1 with digital ISM technology saves up to 60% of maintenance and calibration costs and ensures maximum uptime compared to less reliable pH sensors.
Accurate and continuous availability of pH data enables enhanced process control for higher yields and defined batch times.
InPro X1 pH has passed the US military's MIL-STD-810H drop test. But we decided to go a step further and give the sensor to the drummer in the METTLER TOLEDO Garage Band. Will the sensors survive? Will they still measure accurately afterward? Find out in the video.
"We chose to install METTLER TOLEDO equipment consisting of an InPro X1, a housing, and a transmitter with a display. In addition to obtaining reliable measurements, thanks to robust equipment that complies with hygiene and food safety rules, this installation has had two major impacts: the first is a field benefit, with a simplified pH reading on the transmitter and the absence of recalibration during the process.
The second impact is a product benefit with an optimization of our liquid process that has made it possible to obtain a powder with the expected chemical profile, without heterogeneity in the samples taken during manufacturing."

Digital, Food-Safe, In-line pH Sensor With its unbreakable X-Chip™ technology, the InPro™ X1 HLS offers extremely safe and highly reliable pH measurement
For decades, the food and beverage industry’s been looking for a food safe, in-line pH sensor that withstands cleaning processes. As detailed in this white paper, the InPro X1™ provides exactly this.
The METTLER TOLEDO Process Analytics Catalog provides a comprehensive overview of solutions for analytical measurements in liquid process applications, pure water monitoring and gas-phase measurement.
The control and measurement of pH is vital in a wide range of processes across the pharmaceutical, chemical, and food & beverage industries. But what exactly is pH, why is it so important, and how do pH sensors work? Our complimentary guide has all the answers.
Over time and through use, pH sensors are affected by their measuring environment, which reduces sensor lifetime. Periodically, sensors require cleaning, calibration and adjustments to ensure accurate and precise measurements. Proper sensor care can dramatically increase pH sensor lifetime.
With its unbreakable* X-Chip technology, the InPro X1™ SLS offers extremely safe and highly reliable pH measurement for food or beverage production processes. The sensor’s low drift and long lifetime reduce handling, calibration and replacements costs. Its rapid response to pH changes improves process control, leading to lower consumption of additives and defined batch times.
The only difference between the two models is that the SLS sensor withstands steam sterilization and CIP, whereas the HLS sensor only withstands CIP.
InPro X1 has passed the US military's MIL-STD-810H drop test, meaning that it survived being dropped multiple times from 5 feet onto steel-backed concrete.
The glass shaft of traditional sensors is fragile and can easily break during use and maintenance. The InPro X1 has a solid body, which means it won’t break and will easily tolerate tough process conditions.
Yes, both the HLS and SLS models will withstand clean-in-place processes. In addition, the SLS can be steam sterilized.
Due to the innovative design of the InPro X1, it has very low drift, even at high temperatures. This means that the interval between calibrations can be up to twice that of conventional pH probes.
Intelligent Sensor Management technology improves sensor maintenance by enabling proactive and predictive maintenance strategies. ISM continuously monitors a sensor's condition and performance, and provides real-time diagnostics that tell you when calibration or replacement will be required. This helps to reduce unplanned downtime, extend sensor life, optimize maintenance schedules, and ensure consistent measurement accuracy.
The InPro X1 does not have a glass shaft, so there’s no risk of glass fragments contaminating product. And as the sensor is made from food contact materials, it’s approved for use in F&B production. These two facts combined mean that the InPro X1 can be safely used directly in production instead of relying on sampling and lab measurements.
Also, the InPro X1 will tolerate CIP and SIP processes; therefore, it can be cleaned along with the system. In addition, it features ISM predictive diagnostics. These tell you – to the day – when sensor maintenance will be required. This means that sensor calibration and replacement can be planned in advance in order that production is not impacted.
The InPro X1 is a digital, in-line pH sensor designed specifically for food and beverage applications. Its X-Chip pH-sensing technology is unbreakable; therefore, there is no possibility of glass fragments entering the production process.
Yes, all wetted sensor materials are certified for food or beverage contact applications. The certificates available include 3A, EHEDG, EC1935/2004, ATEX and FM.
X-Chip technology: The unbreakable design of the pH-sensing element, the X-Chip, means glass fragments cannot contaminate food or beverage production.
Withstands clean/sterilize-in-place processes: Repeated CIP processes can severely affect a pH sensor's ability to measure correctly and reduce sensor lifetime. InPro X1 HLS withstands many CIP cycles without accuracy or lifetime being impacted. InPro X1 SLS also withstands SIP cycles.
Predictive diagnostics: Intelligent Sensor Management (ISM) technology in the InPro X1 predicts the number of days remaining until sensor calibration or replacement should be performed.
The InPro X1 pH sensor is available in 120 mm and 225 mm lengths.
The InPro X1 was successfully tested and is used for in-line pH measurement in dairy applications such as yogurt, cheese, and butter production. The combination of X-Chip pH sensing technology and pressurized Argenthal reference system is suitable for almost all F&B applications within the specified conditions 0-80 °C (100 °C for cleaning) and 0-4 barg.
