Hanna 4-1 tester the cheapest I seen

[GodBud]

You should have the 4.01, 7.01 and then one for the TDS calibration 1413uS/cm. You can use the 4.01 as storage solution.

There is no need for the 10.01 solution the unit is designed to work with the 2 point set 4.01 & 7.01 for the Ph calibration.

Yes it is a very good price for that unit.

Zan,

I bought the Hanna HI 991404 unit got it for 120 bones brand new. What do you think about this meter http://cgi.ebay.com/ws/eBayISAPI.dll...m=280058119425

It came with the 4.01 and 7.01 and the 1413 solutions. What do you mean using the 4.01 as a storage solution and what do you mean when you say the unit is designed to work with the 2 point set 4.01 & 7.01 for the Ph calibration. Sorry nube here.

One more thing both the probes on the unit are designed in line if you want to do it that way. This seems a lot more sturdy to do it this way than just mounting the meter to where the probes are just dandling. That proposes a design problem with my res as far as mounting the meter. However if I had the probes in line that just seems more practical but I dont know of any fittings to accomodate both probes and an outlet to distribute my nutes to the irrigation system. Any ideas.

Thanks bro

later
