MA884 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

2432509 Bacteria Tests: Hach Slime Forming Bacteria 9 pk by AquaPhoenix

BART biodetectors are excellent diagnostic tools to help identify the presence of process disruptors, such as bacteria creating slime layers and limiting disinfection.

The SLYM-BARTs can be used as a P/A test capable of indicating to some extent the possible population size and the types of slime-forming organisms present in the water sample. Slime-forming bacteria are able to produce copious amounts of slime without necessarily having to use any iron. Iron bacteria also produce slime, but usually it is thinner and involves the accumulation of various forms of iron.

Slime-forming bacteria generally produce the thickest slime formations under aerobic (oxidative) conditions, which develop around the floating ball. Growth may be recognized as a cloudy or gel-like growth, which can be localized or occur throughout the sample. These growths are usually white, grey, yellow, or beige in color and can darken over time.

• Simple yet effective method for monitoring the population size and/or activity of specific groups of bacteria
• Easy to use, requiring no elaborate or costly equipment and no specialized training
• Effective and affordable tests are easy to interpret and can be performed at room temperature in virtually any environment

18004-16 Traceable ONE Single-Use USB Temperature Data Logger, 10 Day, 1 Minute Interval, -20 to -15°C; 10/pk by Digi-Sense

These data loggers can be used for monitoring and recording temperatures during shipments, storage, or experiments. They are ideal for food, pharmaceutical, or laboratory use any application where a small accurate datalogger is required.

The data logger features a time delay of 30 minutes so the logger will not alert when the temperature is within the alarm zone, until the delay time elapses. Protective plastic pouch keeps logger dry, eliminating concerns when shipping materials with cold packs, ice, or in damp environments. To maintain IP67 waterproof rating, do not tear open pouch before data download.

Products have an individually-numbered 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.

• LED alarm indicator for visual status indication
• Time delay of 30 minutes before logging begins for enhanced logging accuracy
• Protective plastic pouch maintains waterproof IP67 rating
• Bar code for in-house scanning
• Includes NIST-Traceable certificate from our A2LA accredited (1750.01) calibration laboratory
• Compact, single-use datalogger with 10 day logging duration in 1 minute intervals
• Low to High alarm parameter range of -20 to -15°C

Includes

Battery (3.0 V CR2450 lithium) and NIST-Traceable calibration certificate with data.
