PID Temperature Controller Kit, CGELE Voltage AC 100~240V Comes with SSR 40DA Solid State Relay, K Type Thermocouple Sensor, and Black Heat Sink

Awesome pid controller for my heat tempering oil. Perfect size Perfect price and good instructions. You cant go wrong with this ine

Works great! I used it to cycle a heat gun on and off to maintain temperature in a container for a science project. I barely used its features. I didn't use the PID, just on off and it maintained temperature plus or minus 3 degrees.

Although the instructions were clearly no written by someone who was fluent in English, the device itself performed flawlessly and the kit was excellent.

Temp was off about 14 degrees out of the box. The instructions are cryptic to say the least.Wiring it up was straightforward, then I saw temp was off, so a quick look at the instructions says P13 is temp offset. OK, dig through instructions to find how to get to setup. In the flowchart it shows to hold SU (SV? can't read it) for 25 seconds. OK, got it. it turns to P00, you can then hit up/dn keys to scroll through settings, but ... P13 never comes up.P00 is data lock, the manual shows valid values are like 0,1,18, etc. but doesn't say which does what.If you buy one of these, 0 locks out most settings, 1 opens a couple, 18 opens more.So to set temp offset, hold the button for 25 seconds, when it changes to P00 set the value to 18, now you can get to P13 to put in a temperature offset. (it is concerning that the offset is this large, most of my other controllers are name brand and I've never needed this big of an offset)Also of note: I'm running a heater on this, 1800 watts, in a room with an ambient temp of 55F. The heatsink hit 110F !!! There seems to be quite a bit of internal resistance on these SSRs when there should be essentially none. Needing to de-rate an SSR based on load is a bit concerning, but, for a PID, tc, ssr and heatsink that costs about half of a single Opto22 SSR, I guess I can't complain. it seems to be doing the job.Only time will tell if the thing will last

The pid works and functions well. The programming can be a little difficult to understand but read carefully and you'll get setup in no time. Good luck!

There are some settings that don't appear to do what they are suppose to. One example: "overshoot suppression factor". It did not have any effect on set value overshooting or derivative effect on the PID output. I tested and graphed this setting thoroughly under various loads and temps and it did not do anything.The device reads ice water at 32-33F which is what I would expect. As the temp rises, it gets exponentially more inaccurate. I tried it in a smoker to operate a fan up until the temp reached 225, at which point it should turn the fan off. I noticed the temp was much lower than a variety of other reliable probes and temp readers I had in the smoker grill for comparison and monitoring of this PID controller. I adjusted the target down from 225F to 216F to compensate. It seemed anywhere between 7 and 10 degrees too low at any given time.Since the performance was so disappointing I tried it in boiling water, which should read near 212F. It did not, it read 203F-206F at any given time.This could either be due to the failure of the PID controller to monitor and calculate temps correctly OR the type K probe that is provided with the device. It is brand new and since I do not want to spend more money buying compatible probes to determine this, I am left with no choice but to return this item as defective. This is disappointing.

Very satisfied with this PID temp control. Temp off set only needed to be adjusted by 5 degrees.

a pesar de algunos problemas en aduana el producto llego bien y cuando lo abri estaba todo tal cual lo esperaba
