Review: BAPI Blu-Test Bluetooth Temperature/Humidity Probe

I was fortunate enough to get my hands on a Blu-Test Probe and use it for a few days re-commissioning some air handlers. Here's my review and a few videos on how to use it.

Not long ago I saw that BAPI was getting ready to offer up a Bluetooth Temperature and Humidity Sensor that could be used as a testing probe. Me, being pretty techie, I was all about wanting to try it out and figured it might help out if you were considering purchasing a tool like this. (The Blu-Test is now available for purchase at BAPIhvac.com)

Unboxing and Review of the Blu-Test Probe

I was really surprised when I pulled that big suitcase from my PO Box and wondered how many test probes they sent me. But after getting it home realized it was just the shipping container. Whew!

At the point you take the probe from it’s case you are literally ready to turn it on and take measurements… as far as the probe itself is concerned. You do, however need to get your smartphone ready by downloading the Blu-Test App and pairing the sensor to your cellphone.

Pairing the Blu-Test probe with Your Smartphone

Pairing is actually pretty simple and can be done within the app itself. In my Pairing video I talked about how this version of the app (2.0) will pair just fine using only the app with Android 4.1 (Jelly Bean) and above, but if you have an older phone like mine (2 years or so) and are using Android 2.3.x (Gingerbread) you might need to use your phone settings to pair. To find out exactly how to do that, you’ll have to watch the short video.

After you pair the probe to your smartphone you are ready to start taking measurements.

Taking Temperature and Humidity Measurements

Taking single measurements is pretty easy, just tap ‘Get Measurement’, done. but what really differentiates the Blu-test from most other handheld test probes is that it can keep a log of all your readings and not just a list of readings. You can actually setup system and point names to keep track of which readings were from what locations or units.

All of these extras fall into the Logs feature of the Blu-Test probe and can be viewed later on your phone using the app or by using your File Directory viewer on your phone and going to the BAPI directory where the Log files are kept.

Another great plus to the Logs feature is the ability to email the readings as a CSV file that can be viewed in a text editor or used with MS Excel.

Final Takeway and PROs and CONs

I was able to use the Blu-Test Probe while doing some re-commissioning on some large built up air handlers, so I am reviewing this tool from actually using it and not just making some videos. That said…

PROs

  • The sensor itself gave accurate and repeatable readings and performed flawlessly.
  • Not to mention it is NIST certified and might be required in some cases.
  • Logs feature allows you to separate measurements by unit and point.
  • Ability to email the readings in CSV format directly from your phone.

CONs

  • The App (version 2.0) is not up to par with the sensor (next version will eliminate this from being a problem).
  • Currently no support for iPhones (coming soon).
  • User interface with popups and logging can take some getting used to.

The final take away is that the BAPI Blu-Test Probe is a great tool that works exactly as it needs to. The extras of being Bluetooth enabled, logging and emailing measurements might not be a great fit for everyone, but I believe it really solves some problems for those with specific situations in commissioning and verification of temperatures and humidity levels.

If you decide to purchase a Blu-Test from BAPI be sure to let them know you read the review or watched the videos on The Controls Freak. Maybe they’ll give it to you for a dollar… eh prolly not, but it’s still nice to let them know you are a fellow Controls Freak.

    Hi I was not able to watch the video because of restrictions on my company’s IT system so, I have some questions. What is the temperature range? How much data will it log ie how much time and how many readings? What is the cost of the probes and do you need any other perifferals besides the cell phone to obtain the data? What is the cost? What is the worst case eviroment that the probe can withstand?

    The Blu-Test Probe looks good, what kind of cost are we looking at? and what’s the delivery Timeline?

    Abel,
    Thanks for the info. Did you do any testing to see how long it takes the sensor to adjust to varying temperatures or RH? For example, if using it to measure the outdoor air temp and then the supply air temp. We have instruments that can take up to 5 minutes to settle out when the temp difference is 20 or 30 deg F. Just curious.
    Thanks

      I didn’t quite time anything, but I have used similar tools and hygrometers from Vaisala, Dwyer and other cheapy brands from Grainger etc. I would have to say that the Blu-Test performed to par with the others I have used, if not a bit quicker. This quickness would be akin to the higher dollar sensors that are about $150-200 or higher.
