Portable Turbidity Meter and Bentonite Monitoring

GLP Features Fast Tracker™ with iButton™ tags Continuous measurement mode; Verifies the settling rate of suspended matter. Signal Average ( AVG) mode; Accumulates multiple readings giving a final average value. Backlit LCD USB Wines with low phenol contents, such as rosé , light reds and whites should be checked for protein stability before bottling. HANNA is offers a quick test to verify the risk of future protein haze formation. If protein instability is detected, a subsequent test can help define the right amount of bentonite to be added for improving protein stability. It is important not to overdose bentonite to avoid stripping wine flavor, body, and significant loss of color, especially in young red wines. Moreover, adding only the necessary amount of bentonite to obtain the desired protein stability also saves costs. The HI 83749 measures turbidity of samples from 0.00 to 1200 NTU ( Nephelometric Turbidity Units) and is USEPA compliant. In the USEPA measurement mode the instrument rounds the readings to meet USEPA reporting requirements. Range 0.00 to 9.99 NTU; 10.0 to 99.9 NTU; 100 to 1200 NTU automatic range selection 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 1200 NTU Accuracy @ 25° C ± 2% of reading plus 0.05 NTU Repeatability ± 1% of reading plus 0.05 NTU Stray Light < 0.05 NTU Light Source tungsten filament lamp Light Detector silicon photocell Method Ratio Nephelometric Calibration two, three or four points Log Memory 200 records PC Connectivity RS232 or USB 1.1 Environment 0 to 50° C; max 95% RH non-condensing Power Supply 1.5V AA batteries ( 4) / 12 VDC adapter Auto-off after 15 minutes of non-use Dimensions / Weight 224 x 87 x 77 mm ( 8.7 x 3.3 x 3.1" ) / 512 g ( 17.6 oz.)
