Description
The Rosemount 372 is a pH sensor for liquids containing fluoride or hydrofluoric acid, where ordinary pH glass is quickly etched away. Its special fluoride- and acid-resistant glass reduces HF attack by more than a factor of ten, and the double-junction reference resists poisoning ions.
It measures 0–12 pH (0–14 pH without sodium ions) from −5 to 50 °C, or up to 100 °C where no fluoride is present, at −13 to 135 psig. The Ultem body has a ¾ in MNPT insertion thread and a 1 in MNPT submersion thread, and the sensor is supplied with or without an integral preamplifier.
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.
