Detailed introduction of pen-type ORP meters.

A pen-type ORP meter (Oxidation-Reduction Potential meter) is a portable device used for rapidly measuring the oxidation-reduction potential (oxidation-reduction Potential, abbreviated as ORP) of solutions. The ORP value is an indicator to measure the strength of a solution's oxidizing or reducing properties and is commonly used in fields such as water quality testing, environmental monitoring, food processing, and swimming pool management.

The basic concept of ORP

ORP value: It indicates the relative strength of the oxidant and the reductant in the solution, with the unit of millivolts (mV).

Positive value: The solution has oxidizing properties (such as chlorine-containing disinfectants).

Negative value: The solution has reducing properties (such as a solution containing antioxidants).

Application scenarios

Water quality testing: Assessing the oxidation-reduction state of water bodies.

Swimming pool management: Monitor the activity of disinfectants such as chlorine.

Food processing: Testing the antioxidant capacity of food.

Environmental monitoring: Assessing the degree of pollution in soil or water bodies.

Features of pen-type ORP meters

Portability: Small in size and light in weight, it is easy to carry and measure on-site.

Quick measurement: Just immerse the probe in the solution, and the ORP value can be quickly read.

Easy to operate: Usually equipped with one-click calibration and automatic temperature compensation functions.

Versatility: Some models can also measure parameters such as pH value and temperature.

The structure of pen-type ORP meters

ORP electrode: The core component, used for detecting the ORP value of the solution.

Display screen: Shows measurement results (ORP value, temperature, etc.).

Calibration button: Used for calibrating the equipment to ensure measurement accuracy.

Battery compartment: Usually button batteries or rechargeable batteries are used.

Protective cap: Used to protect the electrode from damage.
