WD-35652-00 Precision pH Simulator by Oakton

Ideal for testing benchtop or handheld meters, controllers, and transmitters!

Wide range of output values - Simulate any of following pH values: 1.00, 1.68, 4.01 6.86, 7.00, 9.18, 10.01 and 12.45; and any of following mV values: –1800, –900, –390, 390, 900, and 1800. Push-button selection ensures chosen pH or mV values are exact and precise, unlike conventional simulators where manual tuning is necessary. High-impedance simulation closely matches typical electrode output characteristics.
