MA884-BOX Digital Refractometer for Wine and Grape Product Measurements by Milwaukee

The MA884 is optical instrument that is based on the measurement of the refractive index of a solution. The measurement of refractive index is simple and quick and provides the vintner an accepted method for sugar content analysis.

Samples are measured after a simple user calibration with steam distilled water (starter bottle provided with your unit).

Within seconds the instrument measures the refractive index of the grape. This digital refractometer eliminates the uncertainty associated with mechanical refractometers and is easily portable for measurements in the field.

The instrument utilizes internationally recognized references for unit conversion and temperature compensation.

Temperature (in °C or °F) is displayed simultaneously with the measurement on the large dual level display along with icons for Low Power and other helpful message codes.

Key features include:

• Dual-level LCD
• Automatic Temperature Compensation (ATC)
• Easy setup and storage
• Battery operation with Low Power indicator
• Automatically turns off after 3 minutes of non-use
• Single-point calibration with steam distilled water (starter bottle provided with your unit)
• Waterproof models offers IP65 waterproof protection
• Quick, precise results readings are displayed in approximately 1.5 seconds
• Small sample size as small as 2 metric drops

98766-92 Traceable Dual-Range Light Meter with Recorder Output and Calibration by Digi-Sense

This dual-unit visible light meter measures from 0 to 50,000 lux or 0 to 5000 foot-candles. The photovoltaic cell and microprocessor provide an impressive 0.4 second sampling rate and automatic-zero adjustment. Color-correction filter and precise photodiode produce accurate cosine- and color-corrected measurements over the wide range.

Connect the analog output to a recorder to capture readings, 0.1 millivolt per digit (200 mV max), or display current values on the large 1/2"H digital display. DATA HOLD allows you to freeze current measurements at the flip of a switch.

Traceable® Products have an individually-numbered Traceable® Certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.

This light meter is calibrated using a tungsten light source. If measuring another type of light source, the reading displayed on the meter will have to be manually corrected using the following factors:

• Mercury - (reading x 1.05)
• Fluorescent - (reading x 0.91)
• Daylight - (reading x 0.95)

• Includes NIST-Traceable certificate from our A2LA accredited (1750.01) calibration laboratory
• Swtich between lux and foot-candles; display reading changes color
• Easily read cosine- and color-corrected measurements on the 1/2" LCD

Includes

2" (5.1 cm) diameter photocell with 40"L (1 m ) cable, recorder output, 9 V battery, and NIST-traceable calibration certificate with data.
