The Atago 4422 PAL-22S is a handheld, portable, water-resistant honey refractometer with a honey moisture scale that measures in the 12.0 to 30.0% range, has automatic temperature compensation (ATC), an LED display with external light interference (ELI) technology, and an acrylonitrile butadiene styrene (ABS) resin Ingress-Protection (IP-65)-rated body. Handheld refractometers, also known as sugar meters, concentration meters, or Brix meters, are commonly used in the culinary, food and beverage, pharmaceutical, educational, geological, chemical, and ecological industries, and for water-testing applications.
This refractometer is housed in an ABS resin body for use with honey samples. The 4422 PAL-22S features ATC for immediate, accurate readings, with an ambient temperature range of 10 to 40 degrees C. The unit is factory-calibrated (calibration certificate not included) and can be calibrated with tap water. The metal sides of the sample well allow the sample temperature to conform quickly and evenly to the prism temperature for accurate measurements. The sloped shape eases sample pouring, and helps avoid spills while taking measurements. The outer shell is shaped for easy gripping, with raised grip dots on the back side where the fingertips rest. The LED-illuminated digital display with ELI technology helps provide accurate measurement near windows or outdoors. ELI alerts the user that there is too much light, such as direct sunlight, penetrating through the prism. The unit displays both honey moisture and temperature within three seconds, and comes with a protective plastic storage case with a foam cut-out insert to cushion the instrument.

Refractometers are used to determine substance content in a sample, to provide unit readings of substances including Brix, salinity, and alcohol; to detect chemical impurities, or to measure components of samples such as industrial fluid. Refractometers measure the refractive index of a substance, which is its optical characteristic, and the number of dissolved particles in it. The refractive index is the ratio of the speed of light in empty space to the speed of light in a substance; when light passes from one medium to another. Generally, a low concentration sample has a larger angle of refraction than a high concentration sample. For example, a straw placed in a high-concentration substance appears more bent than when placed in a low-concentration substance. Refractometers can work with natural light, or with an external power source such as batteries or electricity. They typically have either a digital or analog reading display, though some units utilize both types. Some analog-display refractometers can be used for both solids and liquids. Digital-display refractometers are used exclusively for liquids. Types of refractometers include handheld, benchtop, and in-process. Handheld refractometers are elongated and telescope-shaped, or shorter and rectangular. Analog handheld refractometer readings are obtained by looking through the monocular eyepiece and viewing where the boundary line intersects with the memory line. Digital handheld models provide a digital readout. Benchtop refractometers typically measure with a higher degree of accuracy than handheld units. In-process refractometers are used for continuous process monitoring and data readouts, and are generally fitted into a piping system for ongoing analysis. Refractometers are used in a wide variety of applications in the culinary, food and beverage, pharmaceutical, educational, geological, chemical, ecological, and automotive industries, and for water-testing applications.

This unit is a very nice Build and is the current model. I did not purchase mine from amazon, but from Atago Usa directly. I do not represent Atgo. I own and operate a one man Bee and Honey business. I use this for testing my honey before extraction I collect samples and take them back to house and do my testing. This unit takes the guess work out and ensures correct data for my records. Atago customer service is A+. The unit is built very sturdy. Remember To let your honey sample sit about 5 - 10 mins to get to corect temp on the prisim this also lets air bubbles get to the top. Use distilled water to calibrate it makes a difference. The unit can be rinsed with water but not submerged. I compared this to my other refractometer and its right on the number side by side. Only the atago is simpler to calibrate. I should have purchased this along time ago it’s good investment if your into honey. One last thing fill the sample area & prisim up to the metal area this allows the honey to press firmly to the prisim and gives accurate stable readings.

Worth the money for your honey. Pricey but accurate is really important in the honey biz. This was our third brand and it was far superior.

bought this for my father in law and he said it works great so i guess it was a good buy. he never said anything negative about it and he's a tough critic.

This works great and takes a very small amount of honey to work. It also takes temperature into account. There is no guess work. Why did I wait so long.
