The Model S250 is a precision pH/ORP Simulator, for troubleshooting pH & ORP problems.

The S250 simulates the electrode output in the following manner:

• The pH settings include three pH/mV outputs: 4.01 pH (+177.4 mV), 7.00 pH (0 mV), and 10.00 pH (-177.4 mV).
• The ORP settings include two mV outputs: +700 mV and -700 mV.
• The simulator has a High Impedance 1000 Meg-W setting for simulating a pH/mV output to determine if there is a problem with the instrumentation, cabling or amplifier.
• The Model S250 is shipped with a 9V battery and a 3 foot BNC/Hanked (tinned) cable for connecting to various instruments. Optional cable connections are available. See below for list of cable connections.
