2. PRODUCT DESCRIPTION
2.1 Drinking Water Turbidity
The LaMotte 2020 ClearTrace Inline Turbidity System continuously
monitors low-range turbidity and temperature in drinking water
applications.
In the standard system configuration, data is reported through a local
display and a scalable 4 – 20 milliamp current output. All functions can be
accessed through a digital network with or without the local display
interface.
The Turbidity System uses a pre-calibrated turbidity probe mounted in a
DataStick and attached to a sample chamber specifically designed to
prepare water for low-range turbidity measurements. The chamber removes
bubbles from the water sample so that solid particles can be accurately
detected. Because the chamber volume is only 135 milliliters, only a small
amount of a turbidity standard is necessary to perform EPA mandated
calibrations.
A white light source in the chamber lid illuminates suspended particles
with a collimated white light. The chamber lamp will provide collimated
white light for up to two years and is easily changed from the top of the
system.
Measurement data from the turbidity probe is communicated through the
DataStick communication adapter for direct computer communications.
