I just received my new hanna hi99161 meter today , I calibrated it and tested it out and it settles to temp and ph reading way faster than the extech 110 , with in 10 seconds or less the extech takes more than 60 seconds sometimes .
Also I looked under a microscope at the tip and there is no hole for the porous ceramic electrode to complete the circuit , odd .
I will use it this weekend to make Reblochon , and if it works well and does not misbehave I will have an extech 110 for sale soon .
