OMG! This thing is a joke! Has to be calibrated every time!!! WHat the hell! This is insane! I thought this would be quick and easy, just calibrate every now and then like my sons glucose meter! I can do a api test kit so much quicker than this and i thought this was about convenience! No its about hanna making money on contentious sales of these crappy single use packets...hahah. Like you couldn't have me it another way to be sealed and reused? What is the reason you didnt Hanna instruments? Not to mention not one solution to calibrate but 2, and then on top of that cleaning solution and believe even storage solution! This is the biggest rip off I have ever seen in my life! What a scam and who knows about the accuracy!

Mostly just and advertisement for their products, NO useful info on what to do if your ph meter doesn't calibrate like they show it does perfectly in the video. I have yet to have it work the first time

[terrybridgeman]

Are the 20 ml sachets of buffer solution re-usable or a one time use? Also do you wash off the storage solution before putting probe into the buffer solution?

[tonylax]

So when I try to calibrate, it asks for 7 ph to start, if i put it in 7, it then asks for 10. If i start in 4, it than asks for 4. i dont have 10ph solution, what gives? How do i skip 10 and only do 4 and 7?

Hi I recently bought it and have not used it. For the first use, do I need to dip the electrode in ph 7.01 solution for several hours before calibration as mentioned in the leaflet?

Another question- once a sachet opens, can reuse it again for the next calibration and if so how long does it last once opened

[Carlos-nitq]

Me aparece error al querer hacer la segunda calibración, estará dañado el electrodo?

[HeWhomYoutubes]

Just bought one and had it calibrated in store but I put ph down in my water and it kept jumping up ?

[ed.t.hansen]

what good is it if I have to keep it in water, distilled or other ?

[kirstenthomas.]

Mine worked reasonably well for about six months, but it stopped being able to be calibrated. They go on like the one button feature is fantastic. I would personally rather have a second or third button just to be able to have more control over the calibration. Stopped working entirely, and I need to get something else.

[TheVinodkumarbe]

When calibration required? Every testing do we need to calibrate ?

[a.m.s.amarathunga]

I want to know after the calibration how I get pH level of a solution..what should I do?

[bobd]

do you not want us to know how well/poorly this probe does for a titration ?
in that case its response time will show up. as well as just how accurately it
reads outside the calibration range.

if this is all the better you show us how it works or what it can do i'm holding
on to my money. you're guilty of hiding the truth by negligence.

i will pay your website a visit. maybe someone else besides you is
making demo videos there for shoppers

buenas tardes adquiri un tester H198103 pero el instructivo viene en ingles me podrian ayudar en español por fabor

[pablomauriciocastro]

Hola sirve para agua salada salinidad 1.024 a 1.027?

[eddyz]

these hannas are crap stick with the 5 dollar yellow ones of ebay

[Sapere-Aude]

does this one can give accurate ph at 8 9

[bbtraveler]

Can we reuse the Solution in the packets? Or once tested, it no longer good?

[hslabofs]

Hi, may I check how long can this model give accurate reading if we take proper care of it, before we have to replace it with new ones?

[charleswettish]

Do these calibrations need to be done 77f (25c)?
