VERNIER ORP SENSOR
The Vernier ORP sensor measures the ability of a solution to act as an oxidising agent or reducing agent. ORP stands for oxidation-reduction potential. ORP electrodes are often used to measure the oxidising ability of chlorine in swimming pools or to determine when the equivalence point has been reached in an oxidation-reduction reaction.

The Vernier ORP can measure redox potential in the range of –450 to +1100 mV. Readings toward the positive region of this range indicate a strong oxidising agent, while readings toward the negative region indicate a strong reducing agent.






ORP Electrode Specifications:
• Sealed, gel-filled, epoxy body, Ag/AgCl reference

• 1 metre coaxial cable with BNC connector
• Temperature range 0–60ºC
• 12 mm OD
• Impedance: ~20kΩ at 25ºC
• ORP element 99% pure platinum band sealed on a glass stem

Electrode Amplifier Specifications:
(included with each ORP Sensor)
• Calibration (mV)
     Slope: 466.875
     Intercept: –559.793
• 13-bit resolution (SensorDAQ): 0.25 mV
• 12-bit resolution (LabPro, LabQuest 2, LabQuest, LabQuest Mini, TI-Nspire™ Lab Cradle, Go! Link or EasyLink): 0.5 mV
• 10-bit resolution (CBL 2™): 2.0 mV
• Power: 7 mA @ 5VDC
• Input Range: –450 to 1100 mV

Note:
Do not completely submerge the sensor as the handle is not waterproof.

Warranty
  • Warranty: 5 years This product is used in teaching these Australian Curriculum codes:
    ACSCH103 - Equilibrium acids and redox reactions - Oxidation and reduction - A range of reactions, including displacement reactions of metals, combustion, corrosion, and electrochemical processes, can be modelled as redox reactions involving oxidation of one substance and reduction of another substance
    ACSCH110 - Equilibrium acids and redox reactions - Oxidation and reduction - Cell potentials at standard conditions can be calculated from standard electrode potentials; these values can be used to compare cells constructed from different materials
    ACSCH107 - Equilibrium acids and redox reactions - Oxidation and reduction - Electrochemical cells, including galvanic and electrolytic cells, consist of oxidation and reduction half­ reactions connected via an external circuit that allows electrons to move from the anode (oxidation reaction) to the cathode (reduction reaction)
    ACSCH108 - Equilibrium acids and redox reactions - Oxidation and reduction - Galvanic cells, including fuel cells, generate an electrical potential difference from a spontaneous redox reaction; they can be represented as cell diagrams including anode and cathode half­equations
    ACSCH104 - Equilibrium acids and redox reactions - Oxidation and reduction - Oxidation can be modelled as the loss of electrons from a chemical species, and reduction can be modelled as the gain of electrons by a chemical species; these processes can be represented using half­ equations
    ACSCH106 - Equilibrium acids and redox reactions - Oxidation and reduction - The relative strength of oxidising and reducing agents can be determined by comparing standard electrode potentials
