RetractoFit & RetractoFit Bio
The RetractoFit products are manually retractable housings designed for 225 mm sensors in industrial applications with process pressures up to 6 bar. It allows mounting and dismounting of sensors while the process is running. Safe sensor handling is guaranteed because insertion without sensor is impossible, as is removal in measuring position. It is easy to use and maintain: only one press on the red button is needed to move the sensor into or out of the process.
Standard RetractoFit housings (237240 & 237490) have options for either stainless steel or PEEK wetted components. The RetractoFit Bio (237440 & 237480) includes a special rinsing chamber with angled connections for optimal cleaning.
