Description
Overview
GAOTek Water Quality Instrument Portable Ph meter comes with a range of standard sensors including pH, dissolved oxygen, conductivity, temperature, turbidity, depth, ORP, Chlorophyll, Blue-green Algae, NH4+, K+, TSS, Salinity etc. Importantly it offers more customization options that allow you to choose which sensors to the probe based on your projects needed. All our probes are constructed from stainless steel 316 grade that makes it suitable for use in both fresh and industry waters. Default parameters are 5 of pH, dissolved oxygen, conductivity, temperature, turbidity. Still with other 3 ports left to allow you add further sensors to the probe. These auxiliary ports are not restricted, you may take either optical sensor or ion selective electrode from our list.
