Manufacturer: Shanghai Sanxin Instrumentation Brand: Apera Instruments, LLC Model: AI221

The Apera Instruments SX610 pH Pen Tester is featured with reliable measuring performance with a single-button operation in a slim body. A cost-effective choice for your regular pH testing, including hydroponics, aquaculture, water treatment, pools& spas, brewing, and so on. The pH probe is replaceable and suitable for test tube measuring, which is especially suitable for educational use. Easy Auto Calibration (1 point: 7.00) with buffer recognition and 0 to 60˚C Auto Temperature Compensation (ATC), ±0.1 pH/1.0˚C accuracy with 0 to 14.0 pH measuring range. Intelligent functions: switch from ˚F to ˚C, automatic power-off, low battery alarm, pH probe invalidation reminder (remind you to replace the probe for better performance). The meter comes with a complete kit of premixed calibration solutions (7.00), storage solutions (3M KCL), CR2032 lithium batteries all in a portable carrying case. IP57 waterproof and dustproof floats on water, so you don’t have to worry if it falls into the water by accident. The meter is CE certified and comes with a 2-YEAR Warranty (6 months for the probe). The company designs and manufactures scientific analytical instruments like meters and sensors for pH, conductivity, turbidity, and dissolved oxygen for over 25 years, and meets ISO 9001:2008 Standards. NOTES: The instrument will NOT give accurate or stable readings for distilled or deionized water's pH testing. This is because distilled and deionized water do not have enough ions present for the electrode to function properly. To measure distilled or deionized water’s pH, users need to use a specialized pH electrode. Do NOT store the probe in distilled water or deionized water because they will cause damage to the glass membrane of the pH probe. Only use distilled water for cleaning the pH probe.

Sugar Density RefractometerEasy-to-use professional tools measure the concentration of sugar. One year limited warranty from manufacturer.Uses 0-32 BRIX scale (for sorbets). 6.75 length x 1.5 width.Principles of Refractometery Refractometers are instruments used to measure substances dissolved in water and certain oils. The refractometer works using the principle of light refraction through liquids. As light passes from air into a liquid it slows down. This phenomenon is what gives a bent look to objects that are partially submerged in water. To put it simply the more dissolved solids water contains the slower light travels through it and the more pronounced the bending effect on light. Refractometers use this principle to determine the amount of dissolved solids in liquids by passing light through a sample and showing the refracted angle on a scale. The scale most commonly used is referred to as the Brix scale. The Brix scale is defined as: the number of grams of pure cane sugar dissolved in 100 grams of pure water (grams sugar/100 grams H20).

Manufacturer: Grand Index Brand: Grand Index Model: RHB0-80 with Two scale

RHBO-80 Brix refractometer combines two separate Brix ranges in one instrument and covers a total measuring range of 0-80%. Range 1 covers 0-50% and Range 2 covers 50-80%, allowing this instrument to be used on many products and processes. Unit has an accuracy and readability down to 1%. A versitle, two scale refractometer designed to measure solutions falling within a range of 0-80%, and is calibrated to 1%. Ideal to measure concentration in many kinds of liquids related sugar, such as fruit juice, canned foods, condensed milk, liquid sugar and jam and other applications requiring concentration measurements over a wide measuring range up to 80° Brix (%weight sucrose). With range selection that can transfer from scale 1 to scale 2 and vice versa being made by a simple rotary control on RHBO-80 barrel, its measurement range was enlarged. It uses ambient light only and no batteries are needed. Made by experienced craftsmen and are unlikely to break down! Included are: a pipette for dropping test fluids onto the prism (never dip the refractometer into the test fluid!), a mini screwdriver for scale calibration, a Users Guide, plus 10 more Extra Pipettes (1 pack)! With CE marking, conforms with the essential health and safety requirements set out by the European Directives Dual, 0-80% Brix Scale (one scale reads 0-50% Brix while the other*reads 50%-80%) in a single reticle, just rotate the Barrel of the unit to shift the Scales back and forth Accurate to ±1.00% Brix Scale Divisions of 1.00% Brix
