Why Accumax
Specifications published, not withheld
Every datasheet is on this site, free and without a form. You should be able to decide whether an instrument fits before you talk to anyone.
In-house R&D and calibration
Meters are wet-calibrated in an IEC/ISO/EN 17025 accredited laboratory before they ship.
Built for the fluid, not the catalogue
Liner, electrode and body materials are selected per application. A meter for slurry is not a meter for treated water.
Since 1992
Three decades of process control instrumentation, from telecom electronics to flow measurement and industrial IoT.
