SMARTRO SC92 Professional Indoor Outdoor Thermometer Wireless Digital Hygrometer Room Humidity Gauge Temperature and Humidity Meter & Pro Accuracy Calibration

Only ordered 5 months ago and it's faulty . Can't get a answer from seller to replace the main unit .

Easy to use and set up, works fine time will tell for reliability.

muy preciso, me gusto.

I like the product as it's easy to use and accurate. Best of all is their customer service. The touch button to turn on the backlight was not working on my unit. I sent a note to their support. They were very responsive and after a few exchanges for problem determination they sent me a new unit which arrived within 2 days. It's great when a company stands behind its products!

Funktioniert wie es soll und Zeit alles gut an

sono felice: precisa , semplice, completa.

I am thus far (2 weeks) quite impressed with the performance of the SMARTRO SC92 unit. Purchased the sensor/receiver package along with 2 additional sensors. After selecting channels and inserting batteries, synchronization occurred quickly and, over a 2-d period, no loss of sensor signal reception was noted. In testing accuracy, all three sensors, when clustered, presented nearly identical readings, +/- 0.1 °F, RH: +/- 4 percentage units. The temperature readings were spot on with that of a lab-quality mercury thermometer. For routine operation, I have 1 sensor in a shaded ‘sun’ room, and 2 at outdoor locations on my property, the most distant at nearly 150 ft from indoor receiver. The distant unit, away from protection of eaves and exposed to elements (rain, yes, but no direct sunlight), is housed in a sensor-protection shield, available from Amazon (under $20). Although the shield is from a different manufacturer, it’s available as a stand-alone purchase (no sensor, no receiver) and readily accepts the Smartro sensor, requiring no modifications. The ability to place a sensor away from the influence of heated structures (e.g., house, outbuildings) fulfills my need to monitor temperature in locations that might require measures to protect cold-sensitive plants. (And yes, a few degrees can make a big difference with sensitive plants). The shielded sensor was 1-week ago exposed to 12 h of moderate showers – no problems noted. As my use of the SC92 system has been short term, I can’t comment on durability and battery life. If problems develop, I’ll report. Also worthy of mention: mounting magnets and conveniently located, soft-touch backlight control on receiver. And kudos to Smartro for not including date/time or other superfluous info on the sensor screen. The lack of clutter is greatly appreciated. On the downside, the numerals on the monitor that represent sensor number are very, very undersized. Since there’s a generous amount of free space in this region of the screen, I recommend that the sensor-number indicators be doubled or trebled in size. Also, the backlight is short lived (around 5 sec), and does not persist through a single cycle of sensor reports. Minor issues in an otherwise great product!
