HI847492 Haze Meter - Highly Accurate Portable Meter for Beer Analysis

Utilizing a nephelometer to test for turbidity caused by haze, the meter is specially designed for beer quality measurements, providing accurate and precise readings every time. Based on a state-of-the-art optical system guaranteeing accurate results, assures long term stability, and minimizes stray light and color interferences.

Compliant to ASBC methods
Signal averaging and continuous measurement mode
Fast Tracker™ Tag Identification System (T.I.S)
25 mm round cuvettes composed of special optical glass
Results reported in Formazin Turbidity Units (FTU)
GLP compliant and allows traceability of the calibration conditions
Data Logging - 200 measurements stored in the internal memory
Easy data transfer with USB port
Backlit Display

Features a powerful microprocessor that calculates the FTU value from the signals that reach the two detectors by using an effective algorithm that corrects and compensates for interferences of color. The optical system and measuring technique also compensates for fluctuations in lamp intensity, minimizing the need for frequent calibration. Fast Tracker™ Tag Identification System allows brewers to record time and location of specific measurements with iButton® tags. The tags contain a unique ID code encased in stainless steel, that when affixed to a tank allows fast, simple and trackable measurements.

These meters also incorporate a continuous measurement mode to measure the settling rate of suspended matter, and a signal average mode to accumulate multiple readings, giving a final average value. For beer analysis, the average mode is particularly useful to measure samples with suspended particles with different dimensions.

Calibration: A two, three, or four-point turbidity calibration can be performed by using the supplied (<0.1, 15, 100, and 800 FTU) standards. Calibration points can be modified if user-prepared standards are used.

AMCO AEPA-1 Primary Turbidity Standard (USEPA recognized): Non-toxic standards are made of styrene divinylbenzene polymer spheres that are uniform in size and density. The standards are reusable and stable with a long shelf life.
