Both the propriety-PVDF stem and the 316L SS braided-tubbing stem coil and uncoil for simple installation, on-site transportation, and compact shipping. No longer do you need a flat bed truck and 60-foot crane to install a 30-foot probe in a 30-foot tank. With the MPXI-F and stem weight attached, the stem of the probe will easily uncoil to be installed in your tank. Additionally, the PVDF stem provides increased flexibility and impact resistance during cold-weather installation.


APG’s proprietary-PVDF stem has been designed to be compatible with a wide range of corrosive media, including H2S. This makes the probe an ideal solution for monitoring many chemicals encountered in the oil and gas, water and wastewater, and chemical industries. With up to seven temperature sensors and optional High Level Switch, an MPXI-F with PVDF stem is the ultimate sensor for monitoring aggressive and volatile chemicals.
