L.J. Star
L.J. Star Incorporated manufactures process observation equipment for manufacturers in many process control industries, including pharmaceutical, food and beverage, oil and gas, and chemical applications. Whether for witnessing mixing, verifying flow, observing reactions, or documenting cleaning, the need for fool-proof process observation depends on process control instruments. These products include sight glasses, lights, sanitary fittings, flow indicators, bubble traps, camera systems, and level gage instrumentation. L.J. Star's components are designed to be crevice-free so as they are in contact with process fluids the parts will not accumulate bacteria or other material. Products are also offered that are designed for clean-in-place and steam-in-place sterilization.
