turbidity meter MicroTOL 2 Turbidimeters are ideal for measuring turbidity continuously in filtered water, raw water, waste water final effluent, and industrial applications. They arrive calibrated and verify readings in seconds. Versatile design allows for one-piece mounting for added ease of installation or multi-piece mounting for installation flexibility. Removable sample cuvettes allow for fast, easy cleaning and calibration. Optics do not contact the sample, reducing the chance of false, low readings. Features:  Specially designed system eliminates the need for a bubble trap and ensures immediate response time Optical design increases accuracy while providing more consistent readings Low, 30-mL sample volume allows for fast response time and inexpensive calibration Two light sources available— white light to meet U.S. EPA method 180.1 regulations and infrared for ISO 7027 Specifications:  Product Type: On-line Range: 0 to 1000 NTU Accuracy: 2% of reading or ± 0.020 below 40 NTU, 5% of reading or ± 0.020 above 40 NTU,  Light source: Infrared Sample ( Flow rate) : 100 to 1000 mL/ min Sample ( Temperature) : 34 to 122° F ( 1 to 50° C)  Resolution: 0.0001 below 10 NTU 0.001/ 0.01/ 0.1 above 10 NTU Model: 20054 Response time: 1 to 20 seconds Output: 4 to 20 mA Display: LCD Dimensions: 9 " W x 14 " H* x 7.75 " D Dimensions ( " W) : 9 Dimensions ( " H) : 14 Dimensions ( " D) : 7.75 Power: 90 to-250 VAC, 47 to 63 Hz CE Compliance: Yes Includes: Desiccant, spare measuring cuvette with light shield, and power supply.
