It's keeping my hearing tobacco at a perfect humidity level between 60 and 65% and operates my humidifier very well if it continues to operate in this way I'll highly recommend also the Wi-Fi connection is very stable for me and I love that I can see the humidity level throughout the day even when I'm at work because when you're curing tobacco leaves it has to be kept within a very finite range or it'll ruin it so I have to rely on this to keep it within range in my very dry climate where I live I don't use the dehumidifier portion of it cuz I don't need that but the humidistat portion seems to work well and it does have a provision to calibrate the sensor so that you get accurate reading it also allows you to set minimum and maximum settings with an alarm if it goes beyond those settings after testing it deliberately making it go into alarm it worked right each time it activated my humidifier when it was supposed to and then turns it off when it's supposed to I also love that it gives you a graph over time of the humidity level the sensor is in that's very helpful to know how consistent the device is working Review: Simple to use (program) and does the job - Works great, easy to setup and use. configurable for 'F or 'C. I like the separate AC outlets on a dongle, but I wonder about the maximum load current capacity of the wiring. I've got a couple 200 watt grow lights and a 600/1500 watt space heater I run to grow tomatoes indoors during the winter. These would overload. I had been using a combo timer/switch with temperature control but after a few months this heavy load killed it. That worked for a while and then it's dinky power switch (relay) quit. So I found this Inkbird and ordered one. I'm sure it would do the job -for a while. As soon as I got it I noticed its quality. So I opened it up. It was an easy do. These days you can tell quality simply by seeing electronic components that have their markings still on the chips. -china removes these markings, but Taiwan and others do not. The Inkbird had all its markings and actually uses a rather powerful microprocessor to facilitate the control process. It remembers its settings when power off and that is an important feature. Very well. Since the last gadget died because of its relay failure, I decided to amp this up a bit. [pun intended] When your crop is dependent on not freezing to death -I hate failures. so.. The Inkbird uses a pair of relays -one for cooling and one for heating. These are separate from each other and rated for 15 amp 120 volt loading. Again, for a while... relays suffer horribly short lives when loaded to the max and cycling on/off many times as a thermostat will do. Then my epiphany.. A trick I use, is to construct a plug-in service box wired with 20 amp 120V grounded sockets, and with a solid-state relay, capable of at least 20 amps AC at 120V. I also use a 16 gage [or more] 3 wire power cord into this box. For extra credit, I use an expensive 'zero-crossing' type solid state switch (SSR). These run a bit hot when powering a 15+ Amp load so I add a big heat sink to the 'SSR' to help extend its life. This type of SSR uses a DC control (one/off) voltage between 3 and 35Vdc, so I add a small 12VDC wall-wart to switch the SSR, and let the Inkbird only power the wall-wart which in turn operates the SSR, which is very low wattage and thus a very light load on the relays inside the Inkbird. Note that this SSR box will operate a window AC as well. Add one of those Kill-A-Watt monitors and you can track the voltage, power and expense of your rig. ## Features - 【Easy to use】 Supports °C/°F display. - 【Dual relay】able to power refrigeration and heating equipment as conditions change. - 【Dual Display Window】Displays measured temperature and set temperature at the same time. - 【Buzzer Alarm】High and low temperature alarms are available when the temperature is over or the sensor experiences a malfunction. - 【Safety】Maximum output load: 1100 W(110 V). Customize temperature and compressor delay, protecting your refrigeration/heating equipment. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01HXM5UAC | | Additional Features | Temperature Display | | Best Sellers Rank | #1,672 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #2 in Temperature Controllers | | Brand | Inkbird | | Brand Name | Inkbird | | Color | Black | | Control Method | Remote | | Control Type | Button Control | | Controller Type | Push Button | | Customer Reviews | 4.6 out of 5 stars 10,319 Reviews | | Display Type | LCD | | Included Components | temperature probe, socket, controller panel | | Item Dimensions D x W x H | 1.3"D x 2.68"W x 5.51"H | | Manufacturer | Inkbird Tech | | Manufacturer Part Number | ITC 308 11 | | Material Type | Plastic | | Model Number | COMINHKPR111236 | | Mounting Type | Wall Mount | | Number of Items | 1 | | Number of Packs | 1 | | Power Source | Corded Electric | | Product Dimensions | 1.3"D x 2.68"W x 5.51"H | | Product Style | Digital | | Shape | Rectangular | | Special Feature | Temperature Display | | Specific Uses For Product | freezer, heating wrap, exhaust fan | | Temperature Control Type | Heating and Cooling | | UPC | 705701511540 705701565505 | | Unit Count | 1 Count | | Voltage | 110 volts | | Wattage | 1100 watts | ## Product Details - **Brand:** Inkbird - **Color:** Black - **Controller Type:** Push Button - **Product Dimensions:** 1.3"D x 2.68"W x 5.51"H - **Special Feature:** Temperature Display ## Images ![Inkbird ITC-308 Digital Temperature Controller Thermostat - Image 1](https://m.media-amazon.com/images/I/71LX6ydzyYL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Is the probe waterproof and usable to control homebrew strike water temp?** A: It is waterproof enough for my freshwater aquarium use, but metal probe does not last 2 years. Mine failed and is off by 4-6 degrees on average but could be off by more than 10 deg. at times which has killed my fishes. I was advised to buy a "thermal well" to protect the metal probe from premature failures. The replacement probes are 30% the cost of the whole unit and be ready to replace it an average of 1 to 1.5 years but as early as 5 months. I have a total of 6 units different models but same probes and 3 failures so far. Hope that helps. **Q: Can I make my deep freeze into a fridge if I plug this into it?** A: I've been running my deep freeze as a Keezer for well over a year now, utilizing this method with zero issues. It worked so well that I use a second one on an old fridge to be able to do temperature controlled fermentation. The cooling of the fridge and a homemade low power space heater keeps my fermentation within +/- 1 degree. Perfect for quality brews. **Q: Can I plug another heat belt into the cold outlet? I have one setup right now, would rather not buy another temp controller** A: You can not plug another heat source in the cold socket. When the set temp for heat is reached (plus the degrees of override you set) the cold plug is activated. Until then the cold plug it is dead (Off). You can use a multi outlet splitter for the heat plug side making sure their power requirements do not overload the units 10 amp capacity. You will not have any control of a second volume being heated. The one probe will just turn the heat outlet on and off and everything plugged in to it. It is either or, not both, allowing ten amps to be plugged into each as they will never be on simultaneously. **Q: Have a glass door cooler want to keep temp at 55 willthe probe wire conform to the door?** A: Depending on how many bends & how small the gap is. Probe wire is about 1/8" and flexible, sharp corners not recommended. Does cooler have another way to insert probe inside? Probe is 3/16 in diameter. Flat door seal should work fine. ## Customer Reviews ### ⭐⭐⭐⭐⭐ So far this is been a very good humidistat *by R***W on May 22, 2026* I've been using this for a little over a week it's been working flawlessly to set up with super easy and works well with the ink Bird app that I already had.
