How tofindan ion, measure a"milli-pH"and otherwise simplify life in your lab. Wecan help. With the most complete line of lab liquid analysis meters, electrodes, and recorders available from any single source. For pH, redox, and specific ions: flouride, nitrate, cyanide. You name it.
Even our least expensive specific ion/pH meter, the 7410, gives you: normal 0-14 p H r e a d i n g ; expanded-scale reading of any two-pH span; a twodecade log scale for monovalent ions; a four-decade log scale for divalent ions; and known-increment and known-decrement scales for simple measurement of ion concentrations. All told, we have six pH meters for your lab (including one that is a lab unto itself, the 7417 portable).
And our 7421 Digital pH meter, for a good-to-thelast-digit look at a "millipH" change.
