BroadSensor measures turbidity with an fiber optics sensor. An 860nm light from the emitter enters the sample via fiber and scatters off particles in the water. The scattered light at 90 degrees,, enters a PD detector via fiber. This follows the nephelometric technique of measurement, and values are expressed in nephelometric turbidity units (NTUs). This follows the ISO7027 standard.
Key Advantages:
• Fiber optics path
• Ambient light rejection technology
• Internal temperature compensation
• Easy to calibrate
• Low calibration solution volume, 50mL minimum
• Automatic temperature compensation
