Description
Overview
GAOTek pro clear aqua sense turbidity meter advanced sensor for pool and wastewater is a basic water quality monitoring digital turbidity sensor. Adopting 90 ° scattered light principle, using infrared LED light source, fiber optic conduction light path design method, the internal increase of filter design, anti-external light interference ability, built-in temperature sensor, automatic temperature compensation, suitable for online long-term monitoring environment.
Features
- A digital sensor with direct output Rs-485 digital signal, supports MODBUS/RTU.
- 90° angle scattering light principle, built-in temperature can be automatically compensated.
- The fiber-optic structure has strong resistance to external light interference.
- The infrared LED light source enhances the filter design, reduces light interference, and is stable.
- Anti-corrosion passivation treatment on the surface.
- Low power consumption of the sensor, internal circuit anti-interference design
