Description
The Rosemount PERpH-X 3400HT is a retractable, high-temperature pH or ORP sensor with a titanium body 21 in or 36 in long. It is fitted through a 1 in compression connector and can be inserted or withdrawn through a ball valve at up to 64 psig (21 in) or 35 psig (36 in), so the line keeps running during maintenance.
In service it measures 0–14 pH or ±1500 mV from 5 to 155 °C (145 °C with the preamplifier) at up to 400 psig. The double-junction reference is rebuildable with selectable electrolytes, and the 3400HTVP version uses a Variopol VP8 quick-disconnect cable.
