HANNA HI98703 Portable Turbidity Meter

TURBIDITY METER The HI 98703 meets and exceeds the requirements of the USEPA Method 180.1 for wastewater and Standard Method 2130 B for drinking water. The instrument has an EPA compliance reading mode which rounds time and date can be checked at the touch of a button. With it’s logging function, up to 200 measurements along with it’s tagged locations can be stored in internal memory and consulted at any time. Data can be later transferred to a PC via RS232 or USB interface and HANNA HI 92000 software (optional).readings to meet EPA reporting requirements. Users will appreciate the accuracy and sensitivity of this instrument, particularly at very low turbidity levels. This instrument incorporates complete GLP (Good Laboratory Practice) functions that allow traceability of the calibration conditions. The last calibration points, time and date can be checked at the touch of a button. With it’s logging function, up to 200 measurements along with it’s tagged locations can be stored in internal memory and consulted at any time. Data can be later transferred to a PC via RS232 or USB interface and HANNA HI 92000 software (optional).  Specification: Range         0.00 to 9.99; 10.0 to 99.9 and 100 to 1000 NTU Range Selection         automatic Resolution         0.01 NTU from 0.00 to 9.99 NTU; 0.1 NTU from 10.0 to 99.9 NTU; 1 NTU from 100 to 1000 NTU Accuracy @25°C         ±2% of reading plus 0.02 NTU Repeatability         ±1% of reading or 0.02 NTU, whichever is greater Stray Light         < 0.02 NTU Light Detector         silicon photocell Light Source         tungsten filament lamp Lamp Life         greater than 100,000 readings Method         Ratio Nephelometric Method (90°), ratio of scattered and transmitted light; Adaptation of the USEPA Method 180.1 and Standard Method 2130 B Measuring Mode         normal, average, continuous Turbidity Standards         <0.1, 15, 100 and 750 NTU Calibration         two, three or four-point calibration Log Memory         200 records PC Connectivity         USB or RS232 Environment         up to 50°C (122°F); RH max 95% non-condensing Power Supply         1.5V AA alkaline batteries (4) or AC adapter; auto-off after 15 minutes of non-use Dimensions / Weight         224 x 87 x 77 mm (8.8 x 3.4 x 3.0”) / 512 g (18 oz.)
