When a pH meter is reading incorrectly the simulator helps determine if the problem is related to the electrode or to the transmitter. It simulates pH and mV values: from 0-14 pH units in 1 pH unit increments (±414 mV). The simulator operates on a 9-volt battery and has a BNC connector, which attaches to the pH cable adapter.
The simulator isolates the transmitter by mimicking the load of a DO sensor. The 4-pin connector attaches directly to the DO cable, in place of the sensor. In doing so, the simulator can help confirm whether fluctuations in the transmitter display are caused by the sensor, or caused by problems with the instrument or cable.
DO Signal Simulator
An essential diagnostic tool for every instrumentation lab. The simulator isolates the transmitter by mimicking the load of a DO sensor. In doing so, the simulator can help confirm whether fluctuations in the display are caused by the probe or EMF interferences. A two position switch allows simulation of either 0% or 100% saturation.
