Our highly reliable bubble sensors and bubble detectors include digital "smart" circuits that can be calibrated to precisely detect bubbles in almost any fluid and tubing material across a wide range of tubing sizes.

Noninvasive bubble sensors

Our noninvasive bubble sensors are designed for any tubing material: steel, plastic (PVC, fluoropolymers including Teflon, polyethylene, nylon, etc.), silicone, glass and others. Standard bubble sensor models are available for tubes as small as 1/16" OD and as large as 1/2" OD. We also offer custom bubble detectors for larger tubes.

Equipment Testing and Reporting

Our company owned and operated production facilities are equipped to perform bubble size testing as small as 0.5 microliters, with complete testing on 100% of shipped parts.  SMD also executes bubble size testing and report generation for FDA approval processes.
