Manufacturer: COLE-PARMER Brand: VeeGee Model: STX-3

Salinity refractometers are useful for measuring the concentration of natural or artificial seawater in aquariums, holding tanks and breeding ponds. They can also be used for controlling the saltwater concentration when preparing pickles, measuring the concentration of saltwater used in rinsing and cooking sea products. Featuring automatic temperature compensation (ATC), an ideal choice for testing in conditions with large ambient temperature fluctuations. What's Included: Transfer pipet and carrying case. Automatic temperature compensation from 50 to 86°F (10 to 30°C) Aquafarming and aquarium testing Largest display available Durable, all-metal design

Manufacturer: ATAGO U.S.A.,Inc. Brand: Atago Model: 2392

These are the successor model to the conventional ATC-1E. Automatic Temperature Compensation feature only. The MASTER-T / PT series is a good alternative choice when the water resistant feature is not a priority. The MASTER-T is made of metal, and the MASTER-PT is plastic. The specifications are exactly the same. For salty and acidic samples, choose the plastic body, MASTER-PT.

Manufacturer: LW Scientific Brand: LW Scientific

Refractometer - BRIX 0-32% scale (sugar content) BRIX Model: The new optical BRIX Refractometer from LW Scientific measures sugar content in liquids, such as wine, beer, fruit juices, soft drinks, milk, colostrum, and yeast cultures. It can be used in the lab or in the field, simply by putting a few drops of liquid onto the prism and reading the scale under ambient light. The BRIX Refractometer features a 0-32% scale, focusing eyepiece, automatic temperature compensation, and comes in a hard carry case. Measuring the quality of equine and bovine colostrum is easy, with BRIX scores of 22% or higher representing good quality in colostrum. 18-21% readings represent colostrum that can be used for second feedings, and scores below 17% will need to be supplemented.

Manufacturer: HQRP Brand: HQRP Model: 884667812141552

HQRP Salinity Refractometer is used to measure, monitor and control the concentration of salt water and brine, especially useful for aquarium and marine applications. This high quality refractometer measures on 2 scales, Specific Gravity (D 20/20) and parts per thousand (‰). With just a couple of drops of aquarium water you know exactly what your salinity is. Vital if you need to check salt levels when preparing sea food and other ocean by-products. Mesurement range: Salinity: 0 - 100 ppt (0 - 10 %), Minimum Division: 1ppt (0.1%); Specific gravity: 1.000 to 1.070 g/cm3, Minimum Division:  0.001 g/cm3.

Manufacturer: ATAGO U.S.A.,Inc. Brand: Atago Model: 3741

The Atago 3741 Pen Urine digital refractometer is handheld and pen-shaped, measures urine specific gravity (SG) in a 1.0000 to 1.0600 range, has an external light interference (ELI) warning, automatic temperature compensation (ATC), and Ingress Protection (IP)-65 and IP-67 ratings. A refractometer measures the refractive index of a liquid or solid in a sample, converts it to concentration in units of percent by weight, and displays the results. Refractometers are commonly used in the optical, chemical, geological, ecological, culinary, food and beverage, pharmaceutical, and educational industries, and for water-testing applications. This refractometer has a compact, ergonomic, pen-shaped body (16 x 3.8 x 1.8cm), a thin prism head for one-handed operation, and two measurement process options. A sample is measured by dipping, touching, or stirring the tip into the sample. The unit has automatic temperature compensation (ATC) for immediate, accurate calibration readings, regardless of ambient temperature, and ca...

Manufacturer: Sinotech Brand: Sinotech Model: RHW-25DATC Color: Blue

3 In 1 hand held Grape & Alcohol Refractometer RHW-25DATC has three scales(Brix, Baume and W25V/V scales) is mainly designed to test the sugar content in original grape juice and alcohol-content by volume of the grape wine made from the fermented grape juice and baume in grapes concentration. It is a metal device that provides you with fast & accurate results. You can measure the brix &baume& alcohol content accurately in seconds! That helps the manufacturer to decide the best time to manufacture the grape wine. Its physical is: if the measured degree of alcohol of grape wine is 1%VOL, it means the corresponding approximate value of sugar content of grape original juice per liter is 16.83g. Guarantee: Offers 1 YEARS WARRANTY Specifications: Measuring Range: 0-25%Vol , 0-40%Brix;Baume:0-22Baume Minimum Division: 0.2%Vol , 0.2%Brix;0.2Baume Accuracy: ±0.2%Vol , ±0.2%Brix (ATC) Temperature Compensation Range: 10°C - 30°C Length : 170mm Weight: 230g Heavy duty (Durable Aluminum) ...
