 Anyone needs 800ppm calibration fluid for HANNA TDS Meter? 
		
		
		I dont know who sells this locally or in Canada.   
	Unless I can find these locally, I will order a few packs from EBAY. I'll probably get 6 packages (two 3-packs) which works out to about $3.50/pack. $7 + $6 shipping = $13US => $13US * 1.2= $15.60 Cdn. => $15.6 Cdn + $5 brokerage fee = $20.6 => $20.60 / 6 = $3.43 => Round up to $3.50 each I won't need them all. Anyone needs some? http://cgi.ebay.com/Hanna-800-PPM-TD...QQcmdZViewItem  |

 I don't know. I need it because I was playing around with the calibration. I couldn't believe that our tap water was less than 5 ppm as that was what it had been reading since I bought it. So I played with the calibration screw. Now, I've messed it up and want to recalibrate.  | 
		
 I will check at work. It has been a will since I been at the tech department .  That is where I calibrate my pH and do meter weekly.
