Hanna Instruments, HI 931001: Precision Simulator for pH and ORP Meters

• Perfect for testing other pH meters
• pH and mV range is user selectable on a small scale
• Automatic temperature compensation at 25°C (77°F)

It is sometimes difficult to work out whether a particular malfunction is due to the meter or the electrode. By simply connecting the HI 931001 to your meter's input socket and turning the dials, pH readings can be simulated from 0 to 14 pH in 0.01 steps. The output signals all correspond to pH values at 25°C and your pH meter should display the same values that can be seen on the simulator's LCD. For the mV range, HI 931001 can simulate output from -1000 to 1000 mV in 1 mV steps.

HI 931001 is supplied complete with HI 7858/1 BNC/BNC connection cable (1 m, 3.3' long), battery and instructions.
