More info

The antifreeze refractometer is an accurate and reliable measuring instrument. It is equipped with a waterproof ABS casing with IP 65 protection level, a large LCD screen for viewing measurement results and an automatic power-off function to increase battery life. It is designed to measure the concentration of ethylene glycol and propylene glycol in aqueous solutions. The user must select the value to be measured from the menu before performing the measurement. Two values can be obtained: concentration in % vol. and freezing point. Very useful for car workshops and industry, since it allows to control the proportion of the mixture and the freezing point of the coolant, which contributes to increasing the useful life of vehicles and machinery. If necessary, the user can calibrate the antifreeze refractometer at any time by placing a few drops of distilled water in the sample well and pressing the key to start the calibration. Manufactured by PCE with reference PCE-DRA 1.

Battery charging cycles
When calculating the life of a battery it will be necessary to know the number of charge cycles that can be performed until the battery does not begin to lose its capacity.
Depending on the type of battery these charging cycles can vary, the most common being the mobile batteries, manufactured Li-Ion or Li-Po, which have a duration of between 300 and 500 charging cycles according to model and manufacturer.
Once thisE limit we will notice how the battery loses duration of operation, arriving to lose up to 25% of its capacity of load.
At this point it will be necessary to evaluate a battery change.
It should be noted that usage and charging habits can significantly affect battery life. For example, factors such as heat, charge the battery several times a day without it is almost exhausted, etc. Will be affectedits duration.
Therefore, to get the most out of the battery we must know when a full charge cycle is performed, and try to avoid misuse of charge, to increase its useful life.
A charging cycle is considered when the battery has been discharged or its 100% charge has been used.
The manufacturers advise that the charge is never made below the 58% battery, since the battery voltage would not fall so lowTo, so you could end up winning up to 4000 charge cycles.
Tips to increase the life of a battery.
  • Avoid extreme heat or cold or very long applications of the device.
  • Charge the battery as often as you can.
  • Fully discharge the battery from time to time.
  • Do not let the battery run out completely before charging.
Below is a table with theDifferent voltages (V), charge cycles (C) and battery percentage (B).
