TekPower TP9605BT Auto Ranging Digital True RMS Smart Multimeter with Bluetooth & USB Connection, Free App Available for iOS and Android

I purchased the device for the data logging feature. I was monitoring a slow process so a sample rate of once a second was OK. If you need to sample at more than a few times a second this product will not work. I used both the Andriod App (with a Samsung table) and USB/PC connections (with a Windows 10 laptop). Both worked as expected. The software is clunky. It is not very configurable so if you need to manipulate or analyze the data you will have to export it to Excel. For simple data logging this is a good value. With better software it would be a great value.

Okay so, let me get this straight. If you plan to use this as a digital multi-meter then its great for that. It has all the essential tools for basically everything you need. But this products main selling point is the ability to connect to PC and bluetooth and its why I bought it. The PC part was.... They need a better, more up to date tutorial that doesnt require so much computer technical skill to know what the tutorial writers 2010 era terminology for probably windows XP meant in todays terms with Windows 10. Oh, And, the software comes on a CD. Not the large CDs. The tiny ones that are like half the size of the ones you are probably familiar with. If you have a DVD drive without a tray, meaning you just slide the DVD in, This WILL NOT LOAD and you will probably get your CD STUCK again requiring computer technical skills to fix. You need an older tray loading DVD drive to even read this CD and believe me, You need the software on it. They really, really should have just included a link to download the software or even a tiny USB drive. Its not that hard. I had to actually buy a DVD drive just because of this, This is 2018. Most laptops don't actually have a DVD drive. Setting up the software is meticulous. But eventually it does actually work and it works pretty good and is stable for me and is definitely something I will use. The bluetooth on the other hand, Haven't got that working I get "could not connect". I try to connect to it using the actual Android settings application and I try the passcode "0000", invalid. "1234", invalid. "00000" and it says could not connect. I honestly think the technician building this accidentally added a "0" and therefore broke compatibility with the application. It probably couldn't connect to the Android device itself because Android doesn't know what to do with just that so thats understandable although very inconvenient that as a result of this I have to bring an entire Windows 64 bit PC everywhere I go with the meter to use this function instead of my phone or tablet. If you absolutely need bluetooth, You are risking a lot but Its still a nice meter. Good luck.

The battery was already down at reception

Functional and affordable! I bought this unit for use as an alternative to a more expensive Fluke Multimeter. I work in an electronics manufacturing facility, and I had the calibration of this meter checked before using it. The reading were very precise, and it checked out better than several Fluke handheld units that we use for product troubleshooting. This meter also has a temperature sensing probe that come with the unit. All of the readings from the meter can be transmitted via Bluetooth to a smartphone, tablet, or PC. The smartphone app allow the data from the meter to be recorded and graphed. This is great for monitoring a test. I will admit that the this meter fells a bit "lightweight" in comparison to a Fluke, and it is likely not as "rugged", but I've been using mine for several months now with no problems.
