Orion 4 or 5 Star was really the next in line. I'm gonna try and find out the deal w/ the Hach LDO procedure for acceptance in my region and go from there. I don't wanna spend all my $ and then find out I could've got the LDO instead for DO.Wed, 30 Apr 2008 12:08:58 GMTlabrathttp://www.wef.org/TechnicalDiscussions/Topic8970-15-1.aspxI'm pretty sure the YSI 5010 DO probe will only work with the YSI 5100 meter (although the probe shown with the XL60 sure looks like a YSI).</P><P>I'm currently using the YSI setup for DO / BOD, and a recently purchased Orion 4 Star pH / ISE meter, which I'm pleased with so far. I had a Fisher XL series meter to test out, but found the Orion easier to use - most likely because I've used Orion meters for over 20 years.Tue, 29 Apr 2008 09:27:15 GMTSueKruegerhttp://www.wef.org/TechnicalDiscussions/Topic8970-15-1.aspxyes, I have been thinking more and more about it. I am really in the market for a pH meter w/ direct readout. It would be nice to have the extra DO option just in case something happens to mine, but I have 2 ysi probes and I found out that they won't attach to the XL60 meter. I have it in my budget to get the XL60, but I don't want to make a jump decision and then regret it later, like when the LDO gets accepted thru EPA.Mon, 28 Apr 2008 14:11:29 GMTlabrathttp://www.wef.org/TechnicalDiscussions/Topic8970-15-1.aspxI don't have any experience with the XL60 but I doubt the YSI probe will hook up to it. Have you considered Hach meters? They have a new LDO DO probe too.Fri, 25 Apr 2008 14:00:59 GMTkeith chapmanhttp://www.wef.org/TechnicalDiscussions/Topic8970-15-1.aspxDoes anyone have any good/bad to say about the XL60? I am in the market for a new benchtop meter - and it is between this and the Orion 5 Star. The only problem w/ the 5 Star is the DO probe. Does the YSI 5010 fit into the XL60? </P><P>Thanks!!Wed, 23 Apr 2008 09:22:03 GMTlabrat
