These 3⁄4" combination sensors are designed for specialty applications for immersion or in-line mounting. The reference cell features a double-junction design for extended service life, and a built-in solution ground. The body is molded from chemically-resistant Ryton® PPS, and the reference junction is coaxial porous PTFE. All sensors are rated 0 to 105°C up to 100 psig, and have integral 4.5 m (15 ft.) cables with tinned leads.

Body is constructed of Ryton® PPS with 3⁄4 inch NPT threads on both ends. The sensor can be directly mounted into a standard 3⁄4 inch pipe tee or fastened onto the end of a pipe for immersion mounting. Mounting tees for flow-through mounting are offered in a variety of materials to suit application requirements.

3⁄4 inch combination pH sensors are available with or without a Pt 1000 ohm RTD temperature element.
