Digital pH meters for sale

Doc B - 15-2-2013 at 20:17

I accidentally ordered 10 instead of 1 so I am now looking to turn my stupidity into an effort of encouragement towards armature scientists by selling the 9 excess meters for AU$75 each (+shipping), discounted from the cost price of AU$86 each.

These meters aren't the standard box looking ones, these have a long replaceable electrode (~10mm OD) that can fit into even a 14/20 flask allowing for in situ testing. Range 0.00 to 14.00 with 0.01 resolution.

First in, best dressed. I can post them world wide.

Would be ideal to post a picture so people have some idea of what they would be buying.

@smaerd Hear hear! no pic no sale!

I can't add pictures because I'm on a tablet, the OS of which doesn't support attachments. The testers are new and in the original box, the supplier currently has no items in stock or listed so I can't even post a link to them. The only thing I guess I can do is drop the price to $50 + postage.

Just by chance the items might have a name as the manufacturer maybe too (or its ACME?), I have seen this before, it is often something like HAL-9000 or other silly nonsensical stuff, I think it got a habit after "2001 Odysee...." ;)

This and a concentric attack by the few in the know with the secrets of the intanet might turn up some information considerably harder then "Its a good one with a long electrode". You can say the same of me and nevertheless I wold feel not completely described and presented then.

And I am seriously looking for a ph-meter with a long electrode to fit through a flasks neck. Have found some cheap and intersting ones but I am not sure about the quality.

Approach the first gobshite in the street and ask them to take a picture. Cameras are a bit more plentyful nowadays compared to back when it was all glass slides and dark rooms.

It's called an EZmeter and it looks a lot like both; the one that you've linked and that I've paid well more than I should have x10.... :mad:

Usually things are much more expensive here so I'm kinda use to it but 3 times the unit price, plus ordering 10 instead of 1.... Come on!

Hey do you still have some of those ACME ph meters?

Doc B - 19-2-2013 at 04:30

I have 10 of the bloody things!

Doc B

I use boiling oxalic acid in some of my processes.

But first I must adjust the pH to about 5 with NH4OH.

I use pH test strips, which is awkward.

I have never used a pH meter and would not know a good one from a bad one.

If i could immerse the probe of the meter you are selling and get a continuous reading as I add incremental ammounts of ammonia, then the whole operation would be much less hassel.

Would the probe get damaged from boiling oxalic acid?

Can I get a new probe if it does?

Can you post the brand name of the meter you have for sale?

Can you post a picture of one?

If yes, then I want one!

It would show the continually changing pH of the mixture but the operating temperature of the probe currently fitted is rated from 0-50'C. There are a variety of other interchangeable probes that could be better suited to your application but I only have the one type.
The brand is EZmeter it looks to be the same or similar to the Hanna HI98103 pictured at http://www.digital-meters.com/chemical-analysis-c2/ph-meters...
Explanation for inability to attach a photo is given above, despite Jockstrap's idea. :P

Thanks Doc B, the only other time I would use one is for an AB extraction. But I may as well get one that is suitable for both purposes.

Doc B - 22-2-2013 at 22:21

Not a problem at all. Good luck and becareful, Id advise you ask Orgy before you buy any. He may tell you in time that you're being ripped off hard, saving you your hard earned....

I wish I had! :(
