Adopting titanium shafts that can withstand harsh chemical environments! Achieving reliable measurements even in solutions containing oxidizers, strong acids, strong alkali solutions, and sulfides.

The InPro 4800 series from Metrohm Toledo has a long operational lifespan under high reactivity chemicals and high operating pressures, significantly contributing to cost reduction due to its low maintenance requirements. By reducing maintenance and electrode replacement costs, the contamination-resistant annular liquid junction (PTFE) and the pressure-compensated double structure of the reference electrode, along with a long diffusion path and unique technical design, have achieved cost savings.

basic information

■ISM (Intelligent Sensor Management) Mettler Toledo's new innovative digital "Intelligent Sensor Management" concept offers a "plug & measure" function. ISM simplifies and improves operations from the initial installation of process analysis systems to maintenance and sensor replacement. ISM technology not only enhances process reliability but also reduces the risk of electrode failure through self-diagnostic capabilities and low maintenance requirements. ■Supports a wide temperature range and achieves high operating pressure It can be used at high pressure over a wide temperature range (please refer to the specifications). ■Improves process safety with flat electrode tips With a flat glass membrane and liquid earth function, it is the optimal choice for media containing particles and fibers. Ground loops can be avoided with liquid earth, and it can also be used as a diagnostic tool. ■Solution Grounding (SG) option The SG function is coated on the electrode body or measurement point of the pH electrode to improve grounding and effectively eliminate the risk of electrostatic interference. Additionally, diagnostic capabilities are enhanced, allowing for parallel measurements of pH/redox.
