Video Transcript for TempMinder RV Weather Stations - Electronic Weather Station - MRI-822MX Review

Today we're going to take a look at the TempMinder Indoor/Outdoor Wireless Weather Station. This will give you an electronic forecast. You can measure your indoor temperatures, outdoor temperatures, and even the humidity. It allows you to select between celsius and fahrenheit. It will give the outdoor temperature range of a -22 degrees fahrenheit up to 140 degrees fahrenheit. You'll notice this has nice, very large easy to read LED display with a blue backlight. Now this does require two triple A batteries. They are not included.

For this demonstration, I have put two in there just to show you the display. You can store minimum and maximum temperature and humidity and it gives you high and low temperature alerts. You can see the base is black in color. The remote transmitter will be white in color. You can receive remote temperature and humidity from up to three locations. This part does include one transmitter. The transmission distance is 426 feet and the transmitter also requires two triple A batteries and again they are not included. Again, for the demonstration, I've put two in here just to show you how you can see the reading. Now to get up to three locations, it will require two additional transmitters that can be added.

We do sell those separately on our website. They're part number RF-MX. Just to give you a few dimensions. First, on the transmitter, overall width is going to be right at 1 and three quarter inches wide, the overall height is going to be right at 5 and a half inches tall, and the depth at the widest point, which would be at the bottom, is right at 1 inch deep. One the base itself, the overall width is going to be right at 3 and seven eighth inches wide, the height, bottom to the top, is 4 and one eighth inches tall, and again the depth, which would be widest at the bottom, is right at 1 and a half inches deep. That should do it for the review on the TempMinder Indoor/Outdoor Wireless Weather Station.

Very happy with this unit. I have tried cheaper ones in the past. They would work hit and miss. I was excited to try this one. Just got home from first trailer ride with the new thermometer...it worked perfect. I think knowing the temperatures we are subjecting our horses to is important. I think many people would be surprised to see the numbers in their trailer. I bought one for my girlfriends trailer too!!! 857928

So glad you carry this make/model! They are the only ones I found that reach transmission to my greenhouse and hold up well! I have a total of 3 of these now as they inable you to do 3 separate channels giving me ability to see varience in temperature in different areas of the greenhouse. Also bonus that they register humidity. Prompt delivery as well. 605487

  • What Exactly Does a Hygrometer Measure
    A hygrometer is an instrument that measures moisture in the air, or humidity as we usually call it. The first one was actually invented by Leonardo DaVinci in the year 1480! The hygrometer function included in a product such as the TempMinder Wireless Thermometer and Hygrometer # MRI-822MX (and the white version # MRI-822MXW) is useful because moisture in the air affects how we feel. 80 degrees is a comfortable temperature for many, but if you add high humidity that same temperature...
