A PROBEST MP301 portable mutiparameter sensor purchased in early 2022 has been operating reliably on-site for over 4 years. A simple adapter replacement was all it took to restore the main unit’s full functionality, demonstrating our equipment’s excellent long-term durability. We also share key pH probe maintenance tips to help users avoid inaccurate readings caused by dried-out internal filling fluid. PROBEST delivers robust analytical instruments and full lifecycle technical support to global water quality monitoring clients.

The global water treatment systems market is growing rapidly driven by water scarcity, urbanization, industrialization and strict water quality regulations, projected to hit US$24.33 Billion by 2035 with a 7.02% CAGR.
