SMARTRO SC42 Professional Digital Hygrometer Indoor Thermometer Room Humidity Gauge & Pro Accuracy Calibration

Good 👍😊

Nice product. New experience

Waste of money as the display automatically turn off in 10 seconds and it becomes a sitting block of metal on desk. Cannot be returned either due to buying policies. It’s a desk clock and you have to press a button to check the time. 😭😭

Value of money

It was very good

Don't buy this, Lots of display scratches are there.

worthless product. The display goes off in 10 sec and each time you have to press button to view time. Completely useless. I bought it thinking it will be usefull at night for diplay. But the display goes off it it is on battery and keeping it plugged with adapter always is not feasible.

why does this reset time everytime it turns off, if power goes we have to start it from first, plus mine stopped working after few hours. its completely dead now. cant even return

I use it for keeping my acoustic guitars at the right humidity levels (40~50%) which need an ajustable calibration offset controls (use humidity pack for control reference). Works fine and nice to have a readout backlighting when needed… (Cheaper hygrometers have no controls and can often be inaccurate up to 10%…)

I brought one checked it via a salt test bang on 75% brought another same as bang on 75%. Very pleased with the accuracy, very easy to use & has a decent magnet to hang up. to verify if your meter is correct put it in a plastic container with a cap filled with salt add a very small amount of water to the salt so you can still pick it up & it doesn’t run, seal it properly leave it a full 24hrs and it should read 75% if not it’s out & needs calibration )

He tenido muchos de estos y este es muy preciso, además se ilumina al moverlo, vale la pena el dinero q vale.

Working great so far and I’ve had for a few months now. Accurate measure and backlight is very bright but not blinding. Great display and easy to read.

Ottimo igrotermometro. Alla fine ne ho acquistati tre…. Dopo averne resi due di altro produttore che non ho trovato affidabili e che non permettevano la calibrazione se non in un piccolo range ristretto, inutile nel mio caso. Mentre questo permette una calibrazione senza vincoli !!! Ottimo prodotto.
