Deskripsi

The HI83749 Portable Turbidity and Bentonite Check Meter ensures protein stability before bottling for great quality wine.

The HI83749 measures turbidity of samples from 0.00 to 1200 NTU (Nephelometric Turbidity Units) and is USEPA compliant.

  • Log and transfer up to 200 measurements.
  • GLP (Good Laboratory Practice) feature for traceability of the calibration conditions.
  • Great for small & medium wineries and advanced hobbyists.

The HI83749-11 AMCO AEPA-1 standards ensure that measurements are traceable to primary reference materials. These standards are used for calibration and performance verification of the turbidity meter.

 

Supplied with Certificate of Analysis

  • Lot number
  • Expiration date
  • Standard value @ 25 °C
  • Reference meter NIST traceable

Provided storage containers

  • Light tight
  • Protects from accidental breakage

 

Principal of Operation

To measure turbidity the HI83749 passes a light beam through the sample that is scattered in all directions. The intensity and pattern of the scattered light is a‰ffected by many variables, such as wavelength of the incident light, particle size and shape, refractive index, and color. The optical system of the HI83749 includes a tungsten fi˜lament lamp, a scattered light detector (90°) and a transmitted light detector (180°).

The HI83749 features a powerful microprocessor that calculates the NTU value from the signals that reach the two detectors. An eff‰ective algorithm is used to correct and compensate for any color interferneces. The optical system and measuring technique also compensate for fluctuations in lamp intensity, minimizing the need for frequent calibration.
