Good morning kassandra. I just bought model #HI98129 PH/EC/TDS combo tester. Reading the manual I couldn't figure out how to change, the temperature units of measurement. This presentation video, made it very easy to understand. I kept press but not, holding mode button. For 6 seconds after the unit was turned off. Thank you for the presentation video. Now I need some distilled water.

I used this in field research and it worked wonderfully. The tolerance is nominal and it is quite portable. Thank you for the upload and product.

Just bought your HI98129. I'm unable to calibrate it even after following all the steps. ph 7.01 solution shows 7.18 and ph 4.01 solution shows 4.57. Can you guide?

Trying to do the two point calibration with brand new HI98129. Always getting the WRNG message when i am switching from 7.01 buffer(HI7007) to 4.01buffer(HI7004). I rinse the electrode in RO water before putting it in 4.01 buffer. What must be going wrong? Please advice..

I'm on my third one this year. My last one lasted two weeks, never dropped, never went dry, used and cleaned daily. kinda getting sick of spending $200 at a time for something that can't last more than a few months.

Are the Hanna meters also made by little children in China for 1 cent per hour or not?

Really like my Hanna combo, but can't your company give names which I can remember? What do I need to calibrate? 1805226 or 2590522 or was it 598643? :(

Hello
Can you help me?
I can't calibrate my HI98129.
I'm using a new 1413 microsiemens solution, but the screen says "Wrong"
My Hi98129 is new too.

What could be the problem?

Bought one of these but when calibrating it tells me wrng when put on to 4.01 solution. Cleaned for over an hour and soaked in 7.01...

Stay away from these. I bought one for christmas and did not work right out of package. And the warranty is not covered because hydro store did not give me a receipt.. what a waste
