Description
Overview
GAOTek portable pH meter is used for testing water quality. It can be installed with up to 4 probes (the built-in pressure sensor is optional) and can measure water quality parameters such as temperature, conductivity, pH, ORP, turbidity, and dissolved oxygen. These parameters can also be replaced by chlorophyll, blue-green algae, NH4+, K+, TSS, salinity, etc. based on customers’ requirements.
Features
- Automatic identification, each probe is digital sensor, easy for replacement
- High degree of integration, can choose sensors with different parameters
- Self-cleaning function, self-cleaning coating film
- window clean, prevent microbial growth, reduce maintenance frequency
