Inkbird PID Temperature Controller Kit, High Voltage 100ACV to 240ACV, Comes with SSR 40DA Solid State Relay, K Type Thermocouple, and White Heat Sink

I have purchased several different brands of these controllers. Inkbirds are the most reliable and easiest to program.

I used this to control a hot plate made from ¾ inch thick aluminum plate and cartridge heaters. I used the auto-tune feature to get started, then tweaked the Ctl and PID settings until I was able to achieve a variation of only plus or minus 0.5 degrees C from the set point, at a steady state temperature. With all the thermal mass in the plate, it was necessary to switch off power to the heater cartridges at least 20 degrees below the set point on initial heat-up, to avoid too much temperature overshoot. I would then switch the heaters back on as it eased up to the set point. I like that you can store an offset to calibrate the K type sensor. Be sure to use a good thermal paste designed for computer cpu’s when mounting the SSR to the heat sink.

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.

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.

When I received this controller there was a piece of tape on the side that sad. "dad". I contacted support and they had no idea why. I did this because I wanted to have this info and I would let them know what happens. It took me a little time to build my unit. I checked my work and it did not work. I notified support. They sent me a diagram for me to check. I did so plus took a couple of pictured some volt/amp readings. They contacted me again and ask for info to send me a replacement at my request. They were very cooperative with my Problem. Recommend them highly. Roy

This is one of the many Inkbird PID controllers that I use for my home brew and to control various functions on my wood fired boiler. The PID controllers are all dependable and accurate temperature control , easy to program and operate. I mounted the controller in the Inkbird plastic junction box and used a switched receptacle to turn the element off at any time. The indicator light on the controller and switch show when the receptacle is activated . The functionality of the PID controller is endless, it can be programmed to adjust temperature over a wide range or a narrow range, simply to turn on and off or to adjust and display voltage percentages , amongst many other functions. An unbelievable controller for the money and the junction box makes a neat , spacious container.

Arrived promptly, everything was functional and no parts missing. After tuning, I am able to control my electric smoker withing plus or minus 5 degrees. There are a ton of tutorials online to help you tune the PID controller to your needs. I do wish they would have included some thermal transfer paste for the heat sink.

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.

debo probarlo para ver si al menos funcionalmente es bueno

Creo que debería ser de mejor calidad los acabados de este producto.
