How To - Using the Hanna HI98194 Waterproof Portable Multiparameter Meter

In this video, we will discuss how to set up and operate the Hanna Instruments HI98194 Portable Multiparameter Meter. This meter measures pH, ORP, EC/TDS, Salinity, DO, Pressure, and Temperature.

It features a backlit, graphic LCD that is easy to read even in low-lit areas. A combination of dedicated and soft keys allows easy operation. The powerful logging capability and digital probe make this multiparameter meter a great tool.

I've noticed that a lot of people are having the same problem with trying to calibrate the DO sensor and they are getting the reading "wrong standard". This happened to myself many times and it is very frustrating, I eventually figured out a work around which I think works very well. Instead of calibrating pH and conductivity first in quick calibration, skip these and immediately go straight to the DO calibration with the empty dry beaker beaker. The DO will calibrate within 1 minute because there are no droplets of pH/conductivity standard on the DO membrane as you have skipped these calibrations. When the DO has successfully calibrated, then go back and calibrate pH and conductivity and you are all set.

I'm not sure why DO isn't first on the list in quick calibration mode as once the DO membrane becomes wet from the pH/conductivity calibration solution, the calibration reading almost always returns "wrong standard", it even does in the video above if you watch closely. You will never be able to shake off every tiny droplet from the highly sensitive DO probe, it must be completely dry in order for DO to be calibrated in my experience. I'd be interested to hear if Hanna agree with my suggested approach to the DO calibration as many people are having problems with it as can be seen from the comments below.

I recently got this equipment and I'm having issues with the quick calibration. It keeps on saying wrong standard at the start of the calibration. I followed all the steps thoroughly and it's taking quite a while to stabilise. What should I do?

[jessicajohnson]

How should we store the probe between usages?

Thank you for your information and it is really useful. However, I got some problems while calibrating my instrument NANNA HI98194. I have done as same as you showed in the video and it is working for pH and conductivity meter and when it comes to DO it says the wrong standard. Therefore I would like to request to solve this problem, please.

Is this device can be used for measuring PH of refinary wastewater?

Hi, Got a flashing DO on a HI 98193 . Have changed membrane and solution but it won't stop flashing. Any help appreciated .

[aungkyaw]

hello @Hanna Instruments what is the difference with HI 9829?

[saidymotladiile]

Hi how do you remove an air bubble from a Nitrate ISE. I tried shaking but nothing is happening.

[noraghaliaoui]

Hi everyone so can you help me please to choose one HI multiparameter what's th difference between HI98194 and HI9829

[judelynpatero]

Hi.. what is meant by "wrong input" for my connector 2 (DO)?

[carlphilliplantecsi]

Hi. Is the calibration liquid reusable?

[mabelpiki]

are you sure that i can do DO quick calibration like you did on the video?cause for me been trying for some time and its still reading wrong standard and i have following the instructions as given.

i have noted from the video when you were doing DO calibration it read wrong standard and you just said click confirm but i didnt see the meter reading confirm, could it be that there is a confirm button to use despite the meter reading wrong standard.

and also how do i clean the probes especially for DO mine has already turned white due to waste deposits...

HOw can I order this product in India?

[nerijocelyncarmona]

Hi, I am trying to do calibration and it just does not recognize the standard as good, I have followed the instructions for both the quick calibration and the single parameter calibration. For 100% it says that it is the wrong standard as it just reaches about 39%, for 0% it does not stabilize even after an hour, so the countdown never finishes. What can I do?

[nadamedhat]

When I do quick calibration it gets to DO & then it says wrong standard what does it mean?

[muntazirbarat]

HELLO. WHAT TO DO WHEN INVALID INPUT APPEAR IN DO CALIBRATION

[adelg]

How do you find the calibration data when using this procedure? i.e. slopes, % saturation, etc...
