I recently bought the Inkbird PID Temperature Controller Kit, and it’s been great! It’s super easy to set up and works exactly as promised. The controls are simple to use, and the temperature stays steady, which is perfect for my project. I’ve used it for a few weeks now, and it’s been reliable and accurate. It’s a great value for the price and has definitely made my work easier. I’d definitely recommend it to anyone who needs a solid temperature controller! I recently bought a 2nd for other projects.

This PID controller is smaller than I expected, but it really functions well and is pretty easy to setup for what you want to control (Heat or Cool). I used it on a powder coating oven and it does great! I would highly recommend this PID controller to anyone that could use it for the same purpose.

final update:It's okay. The calibration seems to drift a little with outside temperature. I'm not sure if I need to insulate the back of the probe and the probe cable or what. It's honestly good enough for something low precision like a smoker, if I weren't so ocd. I made some pretty good barbecue. I expect to get decent use out of this even if I still have to micromanage it a little more than I'd like.The pid settings I ended up using are c:1, P:1, I:5, D:0, and it seems to keep a fairly tight cycling range. (within 15F degrees of set temp).For temperature calibration, using 225F as a reference (using an analog built in grill thermometer), a +25F to +35F correction was necessary, depending on outside temperature. Reference temp needs to be the same as desired temp since the temperature scaling over the total measurable range isn't flat.I used a different ssr than the one provided, btw. Not entirely necessary, but I wanted an inline neon indicator bulb (part of the modified original smoker controller now used as a connector cable) to not glow when the ssr output is off, and while the connector cable is unplugged from the smoker. I did also add a resistor in parallel to the bulb, but that didn't help with the original ssr, and I'm not sure if it's necessary with the replacement ssr, since I installed the resistor before getting the replacement ssr.(old):update 1: temperature readings are way off. Instructions on how to calibrate are nonexistent, in the vague af manual sent with the pid (which may not even be the correct manual, as the image on the amazon page was required as reference to wire the pid), and there's nothing here in the amazon page on how to calibrate it, either.I did find an option which /seems/ to be calibration, which I used yesterday to calibrate to read correctly at 98 degrees (using body temp as a reference; probe under tongue until probe temp stabilized at body temp), but accurate read doesn't hold as temp rises.It measures below actual temp. by around 10 degrees at room temp, but that margin grows as temperature rises. So the only option seems to be to calibrate it to read accurately at the specific temperature you want to measure at or near, and then re-calibrate if you ever need to use it at a different temp. Which is highly inconvenient.It will at least hold stable at a specific temp when calibrated using that specific temp as reference.I hope...(original review):Apparently it's normal for solid state relays to leak some small amount of power when off...I'll create a more complete review later, after some testing.

Excellent PID temperature controller. Arrived in good condition well packaged. Wiring diagram and set up procedures were well defined. It was put into use controlling a very expensive wine refrigerator. It worked perfectly at first turn on and has been working ever cents with any plus or -2° range. I would highly recommend this PID. A friend of mine who brews beer has a very same PID and is also very happy with it. I would definitely buy this unit again. Thank you.

These are great and a super value. I bought 2 of these a few months ago to replace the old mechanical thermostat switch on a hot melting pot, allowing me to install an over temp safety control so we could safely leave the unit on while unattended. Now I'm building another tank and going to be using them again.

Controller itself works, but the included thermocouple is next to useless for many applications. It's very slow to respond to temp changes. Set PID to 60C. Using an inexpensive instant-read kitchen thermometer showed it overshot all the way to 110C, while the unit's thermocouple was only reading 75C and slowly going up by a fraction of a degree every few seconds. It took over a minute for it to move from 75 to 95C despite the actual temperature being steady at 110. If your intended use has very slow temp changes then this might be OK, but anything that heats or cools quickly will need to use a different thermocouple.

well pleased
