Whatever your pH testing requirements, these general purpose pH meters will meet your monitoring needs.


The 66, 67 and 69 Microprocessor-Based pH Meters from ESD provide unique functions such as: millivolts, relative millivolts and concentration in addition to pH. These advanced technology instruments, depending on model, can store 25 data points that are viewable (Spy Function) from the instrument. Computer control and interface through an optional RS-232 port is also offered. pH can be measured to .001 pH units.

Models 66, 67 and 69 offer Sleek Design, Advanced Technology, Rugged Dependability and is the only "drop-in" rechargable pH meter available.



All pH Meters are sold in Kit form (except Model 68 pH) and include the instrument, electrode, buffers (4.0, 7.0 and 10.0) carrying case and instructions.
