Got the device. Check the DIST. water-calibration is not needed, customized from factory. Drop good drinking water cooler. The difference in density matter (blue below the waterline). Drop nezamerzayki. When stated-20гр, in fact-10. Now when you buy "nezamerzayki" for washer will test match the freezing point with actual the spot. In the case of discrepancy adulteration can directly return. Density of electrolyte battery and anti freeze-by itself. Satisfied with the purchase. Recommend store. Buy stock in RF.

Hello good goods, courier brought home, fast delivery device working, only need to calibrate slightly overstated readings, Old bought before from another seller the purchase of a new roller this does not have a urea check if Kamu needs to pay attention. I recommend the producer as well as the goods. The calibration made a comparison with a quality meter for density in the battery.

Good faith seller, I recommend. Delivery in m. o. a week., can + 1-2 days. He wrote that by post of Russia is not tracked, the seller responded promptly by sending tracking from the Chinese website. The courier delivered to the door. In the work the device did not check, I think that everything will be in order (firm ATC), there are reviews.

I measured the usual purchase water from the machine, which does not leave a scale in the kettle-the device shows that it is destyled. Now in thought-can I rinse the system with such water? Or does this device show not exactly? I'll read it, maybe I'm doing something wrong. Pay via Kiwi, so cheaper

The goods from the Russian warehouse, to the Altai Territory flew like on the wings! The piece is interesting, in the photo of the measurement of spitmouth 70%, an electrolyte with a declared density of 1.27 and a wash of calculated to 25 (in fact-6-6

Got in Moscow on the 5th day. Everything looks like everyone else. A bit of distilled water. Testimony is easier to take than an hydrometer, but there are differences from an hydrometer. That's why I'm doing both.

The packaging is a simple postal bag, good though the sdek brought the device safely and safely. The device, fortunately, was surprisingly quality, no complaints and complaints. Definitely recommend to buy.

Shipping fast. The goods are delivered with a whole package. I checked the Caleb on distilled water. All in the tolerances. density, antifreeze, washing liquid has not yet been able to check.

Thank you for the quality goods and fast dbbet. The only thing that is bad instruction from another refractometer, but in principle, everything is intuitive.
