seems very good and both work as they should. Keep them both in the oxymeter box so that they are handy - nice and comforting during these difficult times
Seems to work fine and fast delivery, 15 days
excellent products and respect of the delivery terms.
I'm a doctor, but I'm a regular at home. Saturation will not become a calm value after about 30 seconds, but I think that's what it is. The thermometer needs no power supply on the back of the type c terminal, but the measurement itself is fine. However, if you measure clothes because you are impatient, it will cause an error in the display of Lo, so it is good to insert and remove the terminal.
The tools have arrived and they look good.
The oxymeter works fine. The oxygen saturation level is steady 1 - 1.5 points below the real value (checked with hospital equipment). Since difference is always the same, it is feasible to deduce a safe decision. The thermometer is not good, as temperature difference ranges randomly from 0.2 - 0.8 degrees (checked with a classic old mercury thermometer), so you might indicated 37, but you will be close to 38!
