Portable Redox Smulator
Portable Redox Simulator available Certified to National Standards
The APS2 is powered from a single PP3 9 Volt battery ensuring total portability.
Supplied complete with a BNC process connector, the portable Redox simulator simply replaces the existing Redox electrode connected to the Redox controller. Then when the instrument is powered up, a Redox value can be replicated by the Redox simulator and displayed on the Redox instrument. This is ideal if a process is Redox controlled as it allows the control equipment to be tested and any faults to be found.
The APS2 is a precision instrument like all the devices within our AWE Instruments range and as such it can be traceably calibrated and certified to national standards. When ordering the APS2 portable Redox simulator, it can be supplied complete with a certificate tracing the instrument serial number to a UK Government agency certificate number as evidence to external auditing agencies of the instruments use as a certified device.
Portable Redox Simulator operation
The APS2 is designed to be simple to operate in the field, laboratory or during testing of control equipment. The toggle switch allows the user to select either battery test mode, which indicates when a low power level is present, as this can affect the mV output signal of the Redox simulator. If this indicator light isn't present we recommend charging the battery before continuing with the test.
If the battery indicator light is illuminated then we are able to switch to pH or mV simulation mode by lowering the toggle switch.
If the battery indicator light is illuminated in pH or Redox measuring mode then the battery should be replaced before continuing.
If the light is not illuminated we are safe to continue.
Portable Redox or ORP Simulator
The APS2 portable Redox simlulator (or ORP simulator) has a large pontiometer which allows the desired Redox value to be simulated. The simulated values are ± 200mV, 400mV, 600mV, 1000mV, and 1400mV.
Uses the toggle switch allows the Redox simulator to move to pH simulator mode.
In Redox simulation mode, by simply moving the front mounted potentiometer to the desired value will ensure that the corresponding Redox value is transmitted to the instrument. This should be displayed on the screen of the Redox instrument your are working with.
Simulating Dirty Redox Electrodes
The APS2 has an impedance toggle switch which is labelled 0Ω or 250Ω. This is designed to show the signal transmitted from the Redox electrode which is either dirty, scratched or near end of life. If the corresponding Redox signal is different to the expected value or staying from the desired value then this is indicative of a damp cable, poor connections, failed solder joints or another electrical connection failure.
Portable pH Simulator Features and Benefits
The APS2 Portable pH and Redox Simulator is an exceptionally useful instrument. Normally used to test Redox and pH instruments, the unit is an excellent time saving tool for fault diagnosis.
If control equipment is being called for from a Redox controller, then by simply simulating the corresponding Redox value, its easy to ensure that a pump or solenoid valve is receiving the correct signal.
Additionally - if a pH or Redox value is out of scope we can simulate the pH/ Redox signal and diagnose whether the fault lies with the pH electrode, Redox Electrode, cable or instrument.
For process, water treatment and effluent engineers, the device can be used to test existing instrumentation and ensure that it is acting in the desired manner. Simply remove the existing process Redox electrode and connect the simulator to ensure that the device is able to run through a calibration procedure, when given the correct Redox values. (Each instrument should have the Redox calibration procedure listed within the supplied documentation.)
For system builders working with control panels or PLC's the APS2 Redox simulator is a great time saving device. Where a complex system is operating based on a number of conditions, the Redox value can be simulated to ensure the device is working as intended.
