A Watts Water Technologies Company Online Turbidimeter Specifications Instrument Overview The Online Turbidimeter is specifically designed for measuring turbidity continuously in filtered water, raw water, waste water final effluent and industrial applications. The optional HF Online software allows graphical trending, alarms and filter analysis for multiple networked turbidimeters. The optional ultrasonic autoclean system automatically cleans the optical chamber for finished or raw water applications. Standard Features • • • • • • • • Meets USEPA method 180.1 and ISO 7027 design and performance criteria Range of 0 - 10 NTU, 0 - 100 NTU or 0 - 1000 NTU (depending upon model) One-piece design eliminates the need to mount more than one module per turbidimeter Fast response time and inexpensive calibration due to low ( 30 ml ) sample volume Modular design reduces overall costs Removeable sample cuvettes allow for easy cleaning and calibrating Optics are not in contact with the sample which reduces the chance of false low readings Convenient reusable primary calibration standards Optical design New optical design allows consistant readings with laboratory and portable turbidimeters. Bubble rejection system The optical chamber of the has been designed to eliminate air in the sample while simultaneously creating a vortex cleaning action throughout the optical chamber. Calibration with primary standards is completed using sealed cuvettes, similar to laboratory procedures. This dry method of calibration is fast, clean and reusable. On-screen menu items guide you through the calibration procedure quickly and easily. One-piece mounted design allows for simple mounting and minimal use of space. Increased range of 0-1000 NTU allows for use of low NTU filtered water or raw water. New optical design increases accuracy and provides more consistent readings with online, laboratory and portable turbidimeters. Simple calibration Light source White light is recommended for use in turbidimeters reporting results under US EPA (US standard) jurisdiction. HF scientific has developed NEW krypton filled white light technology with lamp life expectancy up to 7 years. Infrared light is recommended for use in turbidimeters reporting results under ISO 7027 (European standard) jurisdiction. Infrared light is also recommended for waste water final effluent and industrial applications where color is present in the sample stream. Optional data network interface acquisition system The data acquisition system is designed to sequentially collect data from a series of interfaced HF scientific turbidimeters. The software system stores data, prints reports, graphs and alarms on each individual turbidimeter. In addition it can compare filters and monitor individual or multiple filter efficiency.

Dimensions All Dimensions are in millimeters (inches). Provide at least 200 mm (8 inches) of free space above the sensor for easy removal of the flow head and insertion of the calibration standards. These 2 holes will accept up to 4.5 mm (3/16 inch) hardware. These 4 holes will accept up to 7 mm (1/4 inch) hardware (Holes are inside case) Shutoff clamp allows for shutoff of the intake flow during cuvette cleanings and replacements. Backpressure valve allows adjustment of the amount of back pressure, which will help to control flow rate and eliminate small bubbles. Inline Pressure Regulator Max....
