MYPIN TA4-SNR+K Thermocouple SNR PID Dual Digital Display Temperature Controller Dual Type-K Thermocouple

Great little unit for accomplishing basic temperature loop control. I've used it for temperature, and I THINK it will also take a 4-20 ma input. I haven't verified that yet. I tested on K and J thermocouples (make sure to select the right type), and 3-wire RTD. All work fine. The menu structure is FAR easier to access and manipulate than many other compact controllers. Highly recommended!

I installed it in a toaster oven I use to Temper knife steel. It works very well and I haven't had any issues. Easy to install and relitively easy to set up. 5 stars.

Used this on a small powdercoating oven build. Works well for what I'm using it for. I'm not custom tuning so I can't speak to its abilities there, but the auto tune seems to work well enough. I'm able to hold temp +/- 5 degrees of the target. Although it does seem to cycle power output rather dramatically, like more of a on/off, than I'd expect from a PID.

It worked but was somewhat finicky-had Dan not been into electronics professionally he might not have been able to use it.

Easy to use pid!!!I use this to control my heating needs.They are the perfect pid, so much so, I've bought 3 of these pids.Can't go wrong with them and I have no problem recommending them.

It works as it should. It came packaged very good. I had no issues with it at all. It works like a champion!

Nice unit

Product works as described from a functional perspective. The problem I ran into was a temperature slip over time, regardless of the temperature probe type used. It was losing about 2°-5° every hour on the temperature reading. This caused the unit to overheat the water it was supposed to be maintaining. Instead of having water at 150°, the water temp rose to 165° after 3 hours, and continued rising. But, the unit said the water was holding steady at 150°. After a lot of testing and troubleshooting, I found that it needs LOTS of ventilation to slow down the temperature slip issue, but it won't stop it. It was very warm to the touch, but not excessively hot in my opinion - about 115° in a 95° ambiant environment. I tried Inkbird, and it ran cooler, with no temperature slip at all inside the same panel. Electronics inside of a panel should expect to run warm and still be accurate. Not this unit! That was enough to cause inaccuracies to a level of being unacceptable in a Homebrewing application. Once I opened the panel and had a fan blowing on it the whole time, it was a bit more accurate, but still unacceptable temperature slip over a 8-12 hour period. Bottom line, this controller unit will be inaccurate over time. If you your application can tolerate a 20 degree inaccuracy, then maybe this is OK for you. But why do that, when you can get an Inkbird for the same price and know you are getting accurate readings. Just as an FYI, the issue I found was a temperature slip over time, not a calibration issue. I calibrated to start off with, but after 8 hours it was off by 15 degrees or more. I ran a dozen or more tests changing the conditions, parameters and probes. All tests showed temp slip. All the same tests on the Inkbird passed with no temp slip at all. I wasted so much money on replacing probes & a lot of time on testing, only to spend more money replace this MYPIN garbage! Terrible, terrible product!!
