ph neter

Easy to use and calibrate. Watch some videos on YouTube if you have problems with the supplies instructions. Would but again.

I would not buy this unit and frankly I would not buy from this seller again. I did not see any mention of a warranty period in the description when I bought the meter and it appears that to have about a 90 day warranty. If it were that short then it should be mentioned in BOLD in the description. Secondly when I contacted Amazon they said to contact the manufacturer/seller (why they didn't tell me it was expired I can't say). The seller never replied to me directly and Amazon says they didn't try to reach me through their offices. Finally, the unit itself acts poorly. Likely why it's no longer available. The reading on the same sample waiver up to .5 PH. I didn't bother to check as I always assumed that the variance was between different samples but didn't think to check it on the SAME sample. I guess that will be the first step from now on when I get something that is suppose to provide a readout. Check it twice/three times on the same sample. $34 wasted.

I like everything about it. Super accurate and would buy again. 5 stars

If you accidentally calibrate the 4.0 ph with 6.8 solution the unit is rendered useless.There's no way to reset to factory settings.Also,if you store the pens probe in Kcl solution like your supposed to with a ph tester,the sensor rusts

The other reviews were correct - not accurate - unable to calibrate - temperature reading was off by up to 15 degrees! I’m trying to keep my fish safe and if I trusted this tool, they would perish quickly

Never able to calibrate. Very difficult to set up. Can't use regular ph calibration solution

Cannot get to go above 10.4ph in auquous whether using 50g sod hydrox or 100 it caps out at 10.4 when description shows 14. 👎

So easy to use. Seems accurate.
