## Questions & Answers

**Q: Can the tc0521 use an external power source instead of batteries? what happens if i need to record using bluetooth past the expected 30 hr of battery?**
A: Yes, you can use the USB slot to power it up for long time. You can use Bluetooth to transfer data to mobile phone and PC with our  software

**Q: What size/kind of 9vdc plug it requires? standard 5.5mm x 2.1mm is a way too big?**
A: Voltage 9 VDC ( 8-10VDC Max ). Plug diameter : 3.5mm

**Q: Since this doesn't include a bluetooth module, where would I purchase one? What make/model is required?**
A: BT module included

**Q: How long are the probes?**
A: I don’t remember if it came with one, but most of the ones I have are about 3’ long. I use K-type thermocouple leads, K-type probe and a few other K-Type testing accessories with this device and it’s been pretty good so far.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Nice, portable temperature data logger at a decent price.
  

*by W***R on Reviewed in the United States on 8 October 2023*

This unit has a lot of good things going for it:  Well built, decent price, supports various types of Thermo-couples.  I originally didn’t think the unit worked properly as it wouldn’t power up up right - but that was my fault for inserting a battery backwards.  Once that was corrected - the unit worked fine and was easy to use with good read-outs.  I’ve had good luck with various products from Perfect Prime and this one looks like another winner.

### ⭐⭐ 







  
  
    The TC0521 makes me so sad.
  

*by J***F on Reviewed in the United States on 8 October 2023*

I want to love this. Physically it's a great unit, the display is easy to read, the buttons feel good, everything feels like pretty solid quality. Accuracy looks good, and having four channels really lets you do a lot.The problem is that the software is questionable at best. Running Windows 11 on my laptop, after installing I can start up the software and immediately see that the device is connected (via USB or Bluetooth) because the readings on the "soft" device are mirroring the actual device. I can sometimes start the live readings on the chart with a USB connection and see the chart updated in real time, but if I stop and try to restart the readings or do pretty much anything, I can no longer get readings to appear on the chart. Even if I close the graph completely and start a new reading, nothing happens.Via Bluetooth, the device connects easily to the software and updates are again visible on the "soft" device, but I have never gotten the graph to work correctly. Real time readings just don't work. when I give up and hit stop after a minute or two, there is at most 1 reading (and sometimes zero), despite trying reading rates of anywhere from 1 second to 5 seconds.I thought maybe I could try something else, so I loaded Artisan (coffee roasting software) but it doesn't support this device so that didn't help. Connecting to the iPhone app went better, I could see the readings and the graph updates correctly, although the features on the app are severely limited, there's no landscape support, no ability to zoom on the graph, no way to set Y-axis intervals, etc.For the money, I feel like we should get software that works. Something that's updated regularly rather than just left to rot. The phone software's last update was 5 years ago and doesn't even support the display ratios of modern phones (not even my phone which is 4 years old!). The PC software has the distinct scent of Windows 95/98, so who knows how long it's been since they updated it; there's no version info in the zip file.I really bought this to use with software, and using the bluetooth feature. While technically using it with the phone works, I have to wonder for how long? When does the app get to be so far out of date that it's no longer usable? And why bother using the phone app when it has so few features? Since I can't use the PC software with bluetooth, there's just too many features that I can't utilize. I paid for them, but I can't use them. I'll be returning this model and looking for something else.

### ⭐⭐⭐⭐ 







  
  
    Pretty reasonable for the price
  

*by J***F on Reviewed in the United States on 6 January 2023*

I bought the 4 channel USB model, because I specifically needed to monitor temps on my boiler zone pipes (using K-type pipe clamps).  Overall, it works well for what it is.  Reported temps were within ~2 degrees of my reference thermometer, so I didn't need to calibrate anything out of the box (good enough for my needs/accuracy).  I got a 9V adapter to run it off AC constantly, and I use the USB connector to a small IOT server that reads the temps periodically and pushes them to Home Assistant for review/handling.  I wrote my own Linux software using the protocol PDF they publish on their website.My only callout is the USB connector (just a CP210x TTL to USB) doesn't play well with low-grade IOT boards (Raspberry Pi models 2, 3; Nano Pi) -- once you plug in the USB, the readings on the unit freak out and become incorrect in reported temps.  Unplug USB, and it immediatey goes back to being fine.  I suspect it has something to do with how the cheaper IOT boards don't have good USB power rail isolation.  Everything always worked on typical PCs, and I wound up going with an Atom-based Wyse unit to run the USB connection as my server and log ongoing temps.
