Best pH/EC/TDS Meter?

I have a hanna it has to be calibrated but I wouldn't say often I cal it once a month to be safe the solution is cheap u just have to keep the probe wet with the storage solution

 

I am interested in this same question, bump

 

Ultrameter IIâ„¢

In near daily usage for near 10 years.
Same set of probes.
pH calibration shows probe @ 50% life.
Pricey but worth it.

 

IMHO

Anything Hanna makes is OK .. as is OKI
I like the HI98129 @ $140 ish.
Make sure that it is at least 2 point calibration on pH
Expect to calibrate pH 2X a month and EC / TDS 1X a month.
I always recommend that people buy at least 250 ml of the calibration and storage solutions.

 

I have some issues with Milwaukee, Oakton, and Nutridip Meters in the past but my Hanna stuff has always held up real nicely, and need very few calibrations throughout the year, maybe two or three a year.

For portability, I like this one: Hanna Combo Pen - pH/EC/TDS/Temp.

Or for a stationary one (which I prefer) I like this one: Hanna TriMeter Continuous pH/TDS/Temp Meter

Or this one for fewer calibrations: Hanna GroChek Combo Meter - pH/EC/TDS/Temp. with Cal. Check

 

You DID ask for the 'best'. LOL

The one we use at work is a MyronL, ~$750.

I have the Milwaukee SM101, but that is pH only and I am in soil.

Unless you are stuck on a combo, I would suggest separate meters for pH and EC. The cost is about the same.

Big +1 on the 250ml size for solutions and make sure you get all you need. Spare batteries too.

Research is really your friend here.

Any update on what you went with and how it's been working for you?

I'm doing my research too and Milwaukee seems to get better praise than Hanna. Actually DrTrichome was the first person to say anything bad about them that I've heard. Hanna seems 50/50 from reviews.

I think having separate meters is the best choice too, so I've heard. Something about wearing out the sensors quicker(from storing solution?) in the multi units.

Anyways, I'm stuck between the Milwaukee SM801 and SM802 as well.

 

Personally i'd go for the first. I'm assuming there's a price difference between the two? From the figures you've got there there's no difference in how they measure pH and you're never going to need to measure PPMs of over 1990. Looks to me like the benefits of the latter would never see any use.

Hope that helps

go with the 802 I use the same one and it works great. In my opinion you dont want a meter that requires NO calibration, how would you ever know if it was off? I use the 802 and bought a box of 10packets 1500ppm and 10 packets 7.0 calibration for about 20 dollars and a small bottle of storage solution (never let the tip dry out) Calibrating is so easy dont let it scare you, once youve done it the first time you see. also go to walmart or target and get one of those pen type digital thermometers, itll ensure you dial your calibration in perfectly. hope this helped.

 

You will want the 801. You only need to test up to 1999.
In a pinch you could use use a 999 meter just add an equal amount of plain water
(the same water you originally used to start with) to your sample and double the reading.

 

any one recognize the hm digital set with the ph meter and the ec, tds, temp meter.
just got one today and im a bit confused about the tds its reading in the high 700s for plain water at 6.3ph.
i grow in soil so i tested the run of and it had dropped to about 500 and the ph dropped to 5.8. is this normal.
im new to all this tds ppm ec.. stuff is new to me
