Simple to read, simple to use, and affordable, the WS-09 includes a thermometer in the console and can remotely read and update up to eight remote thermometer sensors at the same from the large digit, uncluttered display.
Ideal for Refrigerator / Freezer applications but useful for other temperature applications, the WS-09 includes a display with programmable audible and visual alerts when temperature limits are exceeded.
The remote sensors include two water proof probes for measuring any temperature medium, including refrigerators, freezers, water and soil.
If your refrigerator is metal, wireless signals can not escape (metal acts as a radio-frequency shield). Thus, the transmitters can be placed outside of the refrigerator / freezer for unobstructed wireless communication to the console.
The remote sensors include suction cups to attach to any smooth surface.
The console includes audible and visual alarms when temperatures exceed your pre-set minimum and maximum alarm settings.
The WS-09 includes two remote thermometers and six additional sensors can be added (F007TP, F007T, F007PF) for comprehensive monitoring.
The display console displays temperature, minimum and maximum temperature, which can be reset manually.
The scroll mode allows you to view the indoor thermometer and remote channels without pressing any buttons. In scroll mode, all of the indoor and detected outdoor sensors will be displayed in five second intervals.
Each remote sensor includes dip switches for channel selection and units of measure (degF vs degC).
The sensor search mode allows you to re-sync sensors without removing and re-inserting batteries.

I bought this to monitor several freezers that hold quite a bit of beef from our cows. I also bought a couple more remote sensors for it to monitor.
Pro's: + Capability for up to 8 sensors to be connected. + Accurate sensors. All 5 that I bought were within 0.3 degrees of each other. They can be recalibrated too if you needed. + Decent range for the sensors. Two of my sensors are located in the basement and others are in the garage. The main unit is maybe 30 feet away from the most distant sensor, and through a wall. One sensor occasionally has it's signal lost for a minute but they don't have any trouble otherwise. + Audible alarms can be set for two channels.
Con's: - Why can't alarms be set on all of the channels? You can only set up the alarm for two?!? It wouldn't be any more complicated to add that programming. - The monitor screen has enormously sized digits that only display 3 channels at a time. Seems like it could be set up...
THE GOOD NEWS - If you are going to use this inside your house, and only go through one wall, this system will probably meet your needs very well. You might have a little trouble if the wall insulation in the wall between the sensor and receiver is metal foil backed, and your door to the garage is metal, since this metal blocks radio frequencies. I guess you can always return the item if it does not meet your needs - Amazon is great with returns.
THE BAD NEWS FOR ME - This system does not meet the seller's specification. Line of sight, going through no walls, and one window, the range is 50 feet for one sensor and 45 feet for the other. They advertise that it has a transmission range of 100 feet in most conditions. I tried going through one wall and a window at those distances, and received no signal. I am transmitting the inside temperature of two rooms in my little guest house, that is right next to my main house. So, to get a signal, I had to extend the little sensors at...
Although the first unit I received had a problem that prevented the main console from receiving data from the sensors, the customer service at Ambient was great, and a replacement was sent quickly. This worked fine, and my two freezers are now being monitored. I had some concern that that sensor wire might disturb the door seal, causing some loss of cooling efficiency, but this does not seem to be the case. The wire is very thin and the seal seems to be OK. There is no frost buildup around the wire after several weeks of use.
I was able to place the receiver about 15 feet away but with two walls separating it from the sensors. This is working fine, and I think it would work even farther away.
