Hanna Salinity Tester Stuck in Bootloop

[Adamantium]

Hi all,

I went to change the units on my HI98319, and now it’s stuck in a boot loop. It starts to power on, shows the battery percentage, then shuts off and starts the process over again. I’m leaving the battery out for now, but can’t seem to fix this.

I contacted Hanna, but haven’t heard back yet.

Any ideas? Thanks, all!

Not familiar with that unit but @Hanna Instruments is on the forum frequently I’m sure they will assist you ASAP, they may be effected by the lock downs.

Here’s hoping @Hanna Instruments can help out.

Before this happened, this was my favorite bit of kit.

Had mine do that once. Pulled the battery for a few days, and everything went back to normal.

I wondered if water got into the unit? I could never confirm that, but it was what I was thinking.

Thanks for the response! That’s really odd. I left mine overnight, but trying again I get the same thing. I’ll leave it a few days.

I’m pretty confident no water got in, but who knows. I wasn’t near the tank when I was making the unit change.

And, naturally, today is water change day haha

Yeah I don't think water got in mine either, but you never know, and it sounded logical at the time.

 

[Adamantium]

So weird. And yours just randomly went back to normal and has been good since?

 

[homer1475]

Yup, no issues since I bought it other then being stuck in the bootloop. Measures pretty close to my Milwaukee and calibrated refractometer.

 

[Adamantium]

Good to know. Thanks a lot. Guess I’ll be going back to the stone ages for this water change (hydrometer and refractometer).

 

[homer1475]

Iknow what you mean. I hadn't used my milwaukee in so long, I had to get out the directions on how to use it(zero out and calibrate) when I let a friend borrow the Hanna. lol

 

[Adamantium]

Aaaand of course now my refractometer is all out of whack. I’m thinking my calibration solution might be off. Think I should trust a hydrometer? The floating thermometer-like kind.

 

[homer1475]

only ones that don't need calibration and will always be spot on. Just remember to read the bottom of the meniscus and not where the top of the water is.

I gave up on mine. I just don't trust it after so many questionable readings compared to my refractometer and my Milwaukee.

Sent a quick video to @Hanna Instruments, and with no questions asked they offered to send a replacement. I’m very happy with the service.

Now here’s hoping I get it before the weekend so I can keep up with my weekly water changes. My refractometer seems to be all out of whack (I’m thinking it’s the calibration solution).
