United Science is the inventor and innovator of Mini Sensors that enable ion measurement in the lab or in your process. At only 4 mm in diameter, the small form factor allows measurement in vials, through septa, and in other space constrained areas. The outer sheath is optionally chemically inert PTFE to allow extreme stability. They are available to sense a wide variety of ions in solution. Combined with our TeraDaq handheld dataloggers, they can be used in the field to monitor a process continually. They are the ultimate in ready-to-use off-the-shelf ion sensing solutions. Please browse our on-line product catalog to customize your order to match your sensing needs. Also, check our our accessories which include wireless Bluetooth dataloggers, coaxial connectors, calibration solutions, fluidic manifolds, and debubblers.
