Cocy ~ Lootest Instruments

I have worked in international sales for water quality testing instruments since 2020, building six years of hands-on experience with online sensors, analyzers and monitoring projects.

On this channel, I share practical knowledge about pH, ORP, conductivity, dissolved oxygen, turbidity, residual chlorine, COD and ammonia nitrogen measurement. You’ll find useful content on sensor selection, calibration, troubleshooting, installation and real-world water monitoring applications.

I work with distributors, system integrators, water treatment companies and project buyers around the world. My goal is simple: to make water quality instrumentation easier to understand and help customers choose solutions that genuinely fit their applications.
