Description
The Rosemount PERpH-X 3500P is a high-performance pH or ORP sensor in a Ryton body with 1 in MNPT threads front and rear. Its double-junction reference has a replaceable process-side electrolyte, and you can choose an electrolyte matched to the process: high temperature, bio-film, poisoning, oil, scaling or metal resistant.
It measures 0–14 pH or ±1500 mV ORP from 5 to 120 °C at up to 100 psig. When the reference is exhausted it can be rebuilt rather than replaced, and the SMART preamplifier stores calibration data for quick swaps. The 3500VP uses a Variopol VP8 quick-disconnect cable.
Argonmark Ltd supplies Rosemount instruments across Bangladesh — to pulp and paper mills, water and effluent treatment plants, chemical, textile, food and power plants in Dhaka, Chattogram, Gazipur, Narayanganj and beyond. Send us the model, measuring range, process connection, wetted materials and output you need, and we will confirm the right configuration, lead time and price.
