Spare Laboratory-Grade Polarographic DO Probe with Built-In Temperature Sensor

The HI76483 polarographic probe will provide accuracy and reproducibility when used in conjunction with the HI5421 benchtop meter. The probe body is made from PEI (polethermide) for increased durability and features a platinum cathode and Ag/AgCl anode assembly. The ultra-thin, 12mm design allows for convenient measurement in narrow vessels such as test tubes, wine bottles and Biological Oxygen Demand (BOD) bottles.

With screw-on caps, HI76483 membranes are easy to replace for faster maintenance.The caps are constructed of durable plastic material with polytetrafluoroethylene (PTFE) oxygen permeable membranes. Each cap is easily filled with electrolyte and installed on the probe.
