Описание товара
[1] main technical parameters]
1) product name: hand hold freezing point instrument, automobile antifreeze, refrigerant liquid cleaning liquid, battery liquid specific gravity enhancement type (copper plating) 0~-50
Mainly used for export; in the after-sales service, the factory promised free replacement within six months, free warranty within one year. 2) measurement range and minimum calibration: Name range of measurement minimum scale remark Freezing liquid (antifreeze) freezing point 0~-50 0.2% freezing point determination Battery 1.10-1.4kg/L 0.1 kg/L severe Cleaning liquid 0C - 40C 10C freezing point measurement 3) with temperature compensation function, make the data more accurate 4) the eyepiece has been upgraded, with higher clarity, reducing the observer's fatigue [two, product applications] Refractometer has the advantages of simple structure, shockproof, convenient operation and carrying, clear vision, low price and so on. Sugar series are used in canned food, fruit juice manufacturing, wine fermentation, beverage, fruit, honey harvesting and other fields. Salt series are used in marine aquaculture, aquarium, physiological saline preparation and other fields. Determination of specific gravity of serum protein and urine by medical series. Industrial series freezing point instrument is used in automobile battery liquid, frozen liquid (antifreeze), cleaning liquid detection, machine tool lubrication fluid, cutting fluid detection
[three, product structure]
[four, methods of use]
1) align the refractive prism to the bright direction, adjust the eyepiece diopter ring until the reticle is clear; 2) adjust the standard: before the determination, the standard liquid (pure water), the instrument and the liquid to be measured should be based on the same temperature. Lift the cover plate, and then drop the standard drop of 1~2 drops onto the refracting prism, and press the cover gently with your hand. Rotating calibration bolts (3) make the line of light and shade in the field of view coincident with the baseline (0%); Note: the optical instrument has been adjusted and can be used directly. 3) opened the cover, with a soft cloth to wipe the surface of the prism, take 1~2 drops of measured solution drops on refraction prism, cover the gently press, relative scale read terminator, which is the content of the measured liquid; 4) after measuring, wipe the surface of the prism and the attachment on the cover directly with wet flannelette, and keep it properly after drying. [five, matters needing attention and maintenance] 1) after using, it is forbidden to flush directly with tap water to avoid the water entering into the optical system pipeline; 2) in the use and maintenance should be gently handled, careful maintenance, optical parts should not hurt the surface scratches 3) this instrument should be stored in the dry, dust-free, non corrosive gas environment, so as to avoid the surface of the optical parts moldy; 4) the prism which is contacted with the tested object is consumable. It can not be repaired. Please understand it; 5) the user must comply with the above methods of use, such as damage, not within the scope of warranty, not warranty. Six, the instrument is installed in the special box, accessories have 1, instructions; 2, screwdriver; 3, straw; 4, lint.
