R28R M12 RJT Probe Details


Servotech type R28 sanitary probes were developed to meet the stringent requirements of the New Zealand dairy industry. These sanitary probes are manufactured with industry-standard 3/4″ running nut, Tri-clover or RJT style process connections, and can be supplied as fast response probes. The R28 range is a new advancement of our R27 range which gives many advantages. The new industry-standard M12 connector is used for easy installation & replacement.
