0-25%VOL / 0-40%Brix ATC Alcohol Refractometer with Built-in LED and Adjustable Focus (ZGRW-25ATCBr)

ZGRW-25ATCBr, an Alcohol and Grape Refractometer, is a modified and improved version of traditional refractometer that that doesn't need flashlight or any separate light source. This refractometer has a Built-in LED and 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 sugar concentration in the grapes. It's scale obtains quick measurements and direct reading of alcohol and brix measurements. It's the tool that professional and non-professional winemakers use for alcohol and brix measurements. You can measure the brix & alcohol content accurately in seconds! All you need to do is manufacture a distillate of the liquid to be measured, place the distilled sample on the prism and then view the results. Materials used to build our refractometers are carefully selected to bring out precision and accuracy, thereby giving you the best quality. It provides measurements that are more accurate and stands up better over time because of it's aluminum body. Made by experienced craftsmen so it's unlikely to break down! Because refractive index is very temperature dependent, it's important to use a refractometer with automatic temperature compensation (ATC) to give you the most accurate measurement in any type of environment temperature. We made sure that every ZGRW-25ATCBr is FULLY EQUIPPED with ATC (it is a small bi-metal strip that moves a lens or prism in response to the temperature change) to correct temperature discrepancies during use. We manufacture equipments that perform consistently and provide accurate results. Among our 3 types of refractometer -- traditional, new design and with built-in LED -- only refractometers with BUILT-IN LED doesn't need any separate light source. You can have results even in the darkest area. Invest with the right product! Have ZGRW-25ATCBr, experience and reap the benefits!

Division: Alcohol: 0.20%VOL Brix: 0.20%Brix Accuracy: Alcohol: ±0.2%VOL Brix: ±0.2%Brix Length : 156mm long Heavy duty (Durable Aluminum) Operating Information: Aim the front end of the refractometer to the direction of bright light source or just need to use the built-in light source, and just the eyepiece (focus adjustment) until the reticle scale can be seen clearly. Adjustment of null (also called calibration): Open the daylight plate. Drop one or two drops of distilled water or R.O water on the prism. Close the daylight plate and press it lightly so the water spreads across the entire surface of the prism without air bubbles or dry spots. Allow the sample to remain on the prism for approximately 30 seconds. Then adjust the calibration screw to make the white and blue boundary coincide with the null line. Adjustment of refractometer should be made under the condition of 20°C environmental temperature. And all refractometers have been adjusted to null before you leave it in the storage. After measurement, clean away the measured solution on the surface of the prism and daylight plate with moist cotton cloth. After drying, it should be stored perfectly. Maintenance: Recalibrate occasionally to ensure and maintain the testing accuracy. Adjustment of null: Liquid and specimen should be under the same temperature. If the temperature varies greatly, the null point should be adjusted once per every 30 minutes. After usage, don't use water to wash the instrument, so as to prevent moisture from entering the instrument. As it is a specialized precision optical instrument, you should handle it gently and take good care of it. Don't touch and scratch the optical surfaces. It should be kept in a dry environment, with clean and non-corrosive air, to prevent the surface from turning moldy and foggy. Please avoid strong shock during transportation. If the consumers use the instrument in accordance with the mentioned method of usage, it can be guaranteed that the instrument will be operational for quite a period of time, with its optical performance unchanged.   Accessories included: 1 Pipette plus FREE 1 Pack (10pcs) of PipettesFREE AG13 1.55V Batteries x 3Sturdy protective carrying case with contoured foam lining to safely and securely hold the refractometer insideMini-screw driver Operations Manual to fully utilize the ZGRW-25ATCBr Packaging: Sturdy Protective Carrying Case with contoured foam Warranty: 2 years warranty   The Product   If you have any question(s) or clarification(s), kindly write us at gary@gainexpress.com     Shipping Policy We'll send the item(s) by Registered Air Mail from Hong Kong within 2 business days after we receive your payment.
