pH/mV Simulators

HI8427 pH and mV Precision Simulator by Hanna Instruments

HI 8427 is designed specifically to simulate pH and ORP electrodes to confirm proper functioning of your meter. Standard pH electrode ranges are selectable with a dial on the front panel.

Provided with a universal BNC connector, this unit is also a high impedance tester, for cable and connector inspection with a leakage sensitivity of 109 ohm. This unique tester is a "one of a kind" in the industry that eliminates the need for very expensive M? meters.

HI 8427 is supplied with HI 7858/1 BNC/BNC coaxial cable

HI931001 pH and mV Precision Simulator by Hanna Instruments

Sometimes it is difficult to recognize whether a particular malfunction is due to the meter or the electrode. By simply connecting 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 be able to check the span of your pH meter.

For the mV range, HI 931001 can simulate output from -1000 to +1000 mV in 1 mV steps.

• Simulate output to discover malfunctions
• Simulate temperature
• Provided with universal BNC connector

HI931002 4-20 mA Amperometer, Simulator and Calibrator by Hanna Instruments

HI 931002 is a portable instrument designed by the Plant Repair and Maintenance Operator for the MRO! This portable simulator can monitor and regulate 4-20 mA from practically any process meter with or without a voltage generator. The communication bus from process instrumentation can be simulated in any of the following modes:

Passive drive/Calibrator mode:

Active drive/Simulator mode:

Passive measurement/Tester mode:

Active measurement/Tester mode:

HI 931002 can measure incoming current, provide power, and simulate 4-20 mA output to calibrate your process meter. A large LCD shows values on the display. You can select between drive and measurement modes through a switch on the front panel and two dials allow for quick adjustment of the current.

Order Information:

HI 931002 is supplied with 1m connection cable, battery, 12 Vdc power adapter and instructions.
