Hamilton Polilyte Plus pH Sensors

Hamilton Polilyte Plus is a maintenance-free industrial pH sensor for harsh conditions. Two Single Pore junctions are designed to eliminate clogging, the Polisolve Plus electrolyte is a polymer electrolyte, and the Everef-L reference cartridge is intended for an extended lifespan. The sensor performs well in highly alkaline solutions and in samples with low conductivity. Mikron Proses (Üsküdar, Istanbul) supplies Hamilton process sensors in Turkey and provides application consulting on sensor selection.

Choosing the pH glass

Polilyte Plus is built in several glass types. The manufacturer recommends them as follows: Polilyte Plus H for low conductivity, Polilyte Plus HB for CIP, SIP, autoclaving and fast response time, Polilyte Plus PHI for CIP, SIP, autoclaving and chemical robustness, Polilyte Plus HF for hydrofluoric acid (HF) in the medium at low temperature, and Polilyte Plus XP for high pressure. The VP version integrates Liquid Earth for stable signals and enhanced diagnostics.

Polilyte family

Model	Pressure	Note
Polilyte Plus	10 bar g (H, HB, PHI); 16 bar g (HF); XP: 50 bar g at 60 °C	Industrial pH sensor with Polisolve Plus electrolyte
Polilyte Pro	6 bar g	Maintenance-free pH sensor for water applications, HF-resistant pH glass, Everef-B reference, -10 to 60 °C
Polilyte RX	6 bar g	ORP (redox) sensor with platinum wire, ±2000 mV, -10 to 60 °C

The Polilyte Plus ORP version (platinum wire, ±2000 mV; Arc ±1500 mV) is described separately in the manufacturer’s catalog.
