## What is Hanna Lab?

The Hanna Lab App turns your iPhone or iPad into a full-featured pH meter when used with a Hanna Instruments HALO® or HALO2 pH probe with Bluetooth® Smart technology or a data management system when used with a Hanna Instruments HI98494 or HI98594 Multiparameter Bluetooth Portable Meter or HI97115 Marine Master Waterproof Multiparameter Photometer.

Whether you're in the lab, in the field, or at your desk, Hanna Lab delivers professional-grade measurements with flexible access, reliable storage, and intuitive control.

The Hanna Lab App now features Hanna Cloud compatibility. Once connected, data from HALO & HALO2 probes, HI98494 & HI98594 and HI97115 meters, can be automatically uploaded to Hanna Cloud. Hanna Cloud is a free web-based application accessible from your PC, tablet, or phone. Features will vary depending on the connected device. They include but are not limited to live measurements, trend graphs, log history, device settings, alarms, and target ranges.

•HALO or HALO2 pH Probes

When used with HALO pH probes, functions include:
-Clear and concise calibration screens for calibration of up to 5 points.
-Annotated data points can be saved with measurement-specific information.  When using a Halo2 pH probe annotated readings can be saved on demand or on stability.
-Data is automatically saved every hour. Data can be shared via PDF or CSV format.
-Dynamic graphing provides measurement information linearly. Graph axes may be expanded using pinch-to-zoom technology for enhanced viewing.

When connected to Hanna Cloud, log files from the HALO pH probes can be uploaded automatically or manually from log history. Files on the cloud can be merged and exported with a reduced logging interval. Annotated readings from the HALO probes can be uploaded immediately to the cloud and saved in a separate data file.

•HI98494 or HI98594 Multiparameter Meter

When used with a HI98494 or HI98594 Multiparameter Bluetooth Portable Meter, functions include:
-Data can be shared via PDF or CSV format.
-Downloaded log files with dynamic graphing. Graph axes may be expanded using pinch-to-zoom technology for enhanced viewing.
-GLP information for the previous five calibrations.
-User-selectable measurement units.
-Stay up to date with the latest firmware updates for the HI98594 on the device information page.

When connected to Hanna Cloud, log files can be uploaded automatically or manually in log history. New data added to uploaded log-on-demand files is automatically synced to the cloud. Log files that have been uploaded to the cloud have user-selectable parameters measurement units, and four parameters can be graphed at the same time.

•HI97115 Marine Master Photometer

When used with a HI97115 Marine Master Waterproof Multiparameter Photometer, functions include:
-User-defined method groups for routine analysis.
-Readings can be collected using the app or synced directly from the HI97115 meter.
-Data can be shared via PDF or CSV format.
-Trend data with dynamic graphing. Graph axes may be expanded using pinch-to-zoom technology for enhanced viewing.
-Stay up to date with the latest firmware updates on the device information page.

### 3/5 — It’s ok

*2026-06-10*

There is a lot of bugs in app. I have the marine master and that software is also buggy. In Hanna lab if you choose measure pick any test after hit send to device it says not available in this mode, lol. The marine master itself a lot of tests very wrong. Example HI 774 says shake bottle till dissolved. This is supposed to be shake bottle for 2 minutes. I sent a lot of info to Hanna. Let’s see if they fix it.

**Developer response:** Thank you for you feedback, can you please expand on the info you have sent to Hanna so we can make sure we have the details. We reviewed the tutorial for the HI774 and there is a slight difference but its mainly due to the space on the screen. The tutorial is meant to be a guide and not intended to replace the user manual.

### 4/5 — Joe

*2026-05-15*

Downloaded latest firmware and now cannot connect to device

**Developer response:** Are you able to see if this is fixe din 4.3.3.  If not, please provide your OS version so we can check this directly.

### 4/5 — Does a good job, both the app and device could do a little better.

*2024-09-23*

It does what it needs to, and a good job at that. BUT my only recommendation would be to add the timers during testing into the app, as well as adding timers in the photometer for all timed steps, such as the 30 second shaking for magnesium. If you have a 3 minute timer for waiting at the end of the magnesium test, you can do 30 seconds to time you shaking the reagent.

### 1/5 — Pretty useless

*2023-12-30*

When used in conjunction with the Hanna tester, this app is pure uselessness.

It’s can just import logs from the device, can’t be used to monitor test statuses when in tutorial mode.. I mean.. seriously.

It’s state is reset each time it’s backgrounded and disconnected from the device.

What a waste.

**Developer response:** Hello, We have just made some updates that should resolve these issues. Please update version 4.1 and give us your feedback. Thanks, Hanna Instruments

### 4/5 — Does all I want it too

*2021-11-01*

Great app with all the functions I need, I would update to five stars if they add a dark mode so I can save battery.

### 1/5 — Mise à jour

*2019-07-04*

Depuis la dernière mise à jour il nous impossible de calibrer notre pH mètre

### 1/5 — Bluetooth no longer connects to probe

*2018-12-18*

I’ve been using this app for about nine months. It has worked well although it is always been finicky connecting to the probe via the app. Sometimes it would connect automatically, other times I would have to reestablish the connection manually. Now I can’t get it to connect at all which means I can’t measure pH in my brewery.

### 4/5 — Solid app, great support

*2017-11-02*

I’ve been using the app for about a year and it’s remarkable!  Calibration is quick and I find it easy to read.  

I do wish that there were a few more customization options regarding data logging and calibration slope display.

### 5/5 — An amazing app with an amazing probe...

*2015-12-09*

I have had my Foodcare Halo since they released it, and I have nothing but positive things to say...(to the guy 1 staring this - dude, you don't have to give the app a 1 star because you received a damaged meter. It was most likely UPS, so before you go giving terrible reviews why don't you call the service center. They have been very helpful to me, especially when I broke my first electrode they sent a replacement free of charge). 

It is an accurate meter, affordable, and the app for my iPad mini runs very smooth. I love that it stays accurate over many uses. I mean, the ability to save calibration is very nice.

I've also done data logging with the app, and it is awesome to be able to download the data points to a csv file and create a curve in Excel.

It's a jaw dropper in the kitchen when I get the Bluetooth meter out and link it to my iPad. It's awesome to get such a response to the equipment!

I recommend to everyone looking to get a nice, accurate, affordable pH meter...

### 1/5 — Probe Broken

*2015-10-12*

Was looking forward to using this tool. Paired pH sensor with app and app reported temp sensor was broken, and the pH of my 4.0 buffer solution read 16. Packing unit up and sending it back. Bummer
