1720 Series

The 1720E Turbidimeter reflects nearly 50 years of Hach leadership in turbidity measurement science. Continuously flowing sample flows through the patented bubble removal system which vents entrained air from the sample stream and eliminates the most significant interference in low level turbidity measurement. The 1720E Turbidimeter is not affected by variations in flow and pressure. When connected to an SC controller, 1720E provides versatile output options including 4-20mA Output, Modbus RS485, Profibus, or HART. Instrument specific warning and error messages give confidence in the accuracy of your measurement.
