Generates a set mV value
Connects to any pH or ORP meter
Check the performance of any pH or ORP meter
Also connect any BNC pH or ORP electrode
Using display readings, electrode can be evaluated
The ASI DUO-CHEK helps determine where a failure may occur. This simple devise can be connected to any pH or ORP meter. Generating a fixed mV reading, the unit can detect if there exist any abnormalities in the meter programming or electronics. The ASI DUO-CHEK can also be attached directly to a pH or ORP electrode. When used to display a series of set mV readings, the DUO-CHEK can check the electrode in an inexpensive manner accurately determining its usability.
