Anionic Surfactants Portable Photometer-Kit - HI97769C

HI97769 is an advanced portable photometer for the measurement of anionic surfactants in water. This meter offers a superior optical system that utilizes a reference detector and narrow band interference filters for extremely fast and repeatable measurements. No warm up time before taking a measurement Tutorial mode for step-by-step instructions CAL Check to verify meter performance Present in waters and wastewaters, surfactants are discharged via aqueous waste from households, industrial laundering, and other cleansing operations. Generally present in detergents and other cleaning agents, a surfactant molecule consists of a strongly hydrophobic group and a strongly hydrophilic group, permitting solubility in both aqueous and non-aqueous media. When the hydrophilic group is negatively char Features: SKU:HI97769C,Anionic Surfactants Accuracy:±0.04 mg/L ±3% of reading at 25°C,Anionic Surfactants Method:adaptation of the US EPA Method 425.1 and Standard Methods for the Examination of Water & Wastewater, 20 th Edition, 5540C, Anionic Surfactants as MBAS,Anionic Surfactants Range:0.00 to 3.50 mg/L (as SDBS),Anionic Surfactants Resolution:0.01 mg/L,Automatic Shut-Off:after 15 minutes of inactivity (30 minutes before a READ measurement),Bandpass Filter Bandwidth:8 nm,Bandpass Filter Wavelength Accuracy:±1.0 nm,Battery Type/Life:1.5 V AA Alkaline (3 pcs.) / greater than 800 measurements (without backlight),Cuvette Type:round 24.6 mm diameter (22 mm inside),Dimensions:142.5 x 102.5 x 50.5 mm (5.6 x 4.0 x 2.0 in.),Display:128 x 64 pixel B/W LCD with backlight,Environment:0 to 50°C (32 to 122°F) - 0 to 100% RH (IP67),GLP:yes,Logging Memory:50 readings,Photometer/Colorimeter Light Detector:silicon photocell,Photometer/Colorimeter Light Source:LED with 610 nm bandpass filter,Weight:380 g (13.4 oz.)
