توضیحات محصول

Production Introduction
 
The PH/ORP meter is a high-precision instrument designed for detecting the pH and oxidation-reduction potential of liquids. It operates on the principle of a primary battery and features a microcomputer for user-friendly operation and easy maintenance. Resilient against interference from color, turbidity, colloidal substances, oxidants, and reducing agents, this meter is well-suited for analyzing various media such as clean water, wastewater, industrial water, and chemical reagents. It finds widespread applications in agriculture, environmental protection, and various industries.
 
The sensor is equipped with a composite electrode, effectively eliminating the impact of variable "K" values and ensuring long-term stability and accuracy in pH measurements. The internal structure of the sensor is depicted on the right.

Principle of Measurement
 
The pH meter employs a potentiometric method to measure the pH of a solution. Beyond pH measurement, this device can also assess the electromotive force of a battery. pH, representing the activity of hydrogen ions in a substance, is the negative logarithm of the hydrogen ion concentration. The core components of a pH meter are the glass electrode, sensitive to pH, and the reference electrode, which maintains a stable potential.
 
Combining these two electrodes in the same solution creates a galvanic cell, and the potential of this cell is the algebraic sum of the potentials of the glass and reference electrodes. The reference electrode's potential in the pH meter remains stable. When the temperature is constant, the potential change of the galvanic cell, formed by the solution and the electrodes, is solely linked to the potential of the glass electrode. The potential of the glass electrode, in turn, is influenced by the pH value of the solution being measured. By measuring the potential change, the pH value of the solution can be determined.

Q&A
 
ORP (Oxidation - Reduction Potential)
Oxidation-Reduction Potential (ORP) measures the oxidizing properties of any sanitizer (chlorine) present in the water. ... ORP is probably the most common method used by chemical controllers to measure sanitizer level, and the most inexpensive type of system.
 
What causes ORP to rise?
If there are lots of potent oxidizers around, and not so many reducers, ORP rises because the electrode senses more oxidizing "power" in solution. Likewise, ORP drops if it senses more reducing power in solution. ... Often, ORP goes down as pH rises. A typical aquarium ORP reading will change on the order of 59 mv/pH unit.
 
 
What should be the ORP of drinking water?
Since the movement of electrons is electricity, ORP is measured in millivolts. Drinking water should have a rating of least -50 millivolts, but it's not often the case. Filtered water can have ORP values ranging from 357 to -25, depending on the brand and type of water. It's most often measured using an ORP meter.
 
Why is my ORP level low?
A drop in the ORP indicates an increase in chlorine demand caused by reducing agents or contaminants entering the water. A decrease in ORP indicates that chemical reactions are about to occur. Compared to amperometric control, ORP is considered to be a more accurate measure of disinfection rate.2016年11月14日
 
 
What does a negative ORP mean?
A negative ORP reading indicates that a substance is a reducing agent. The lower the reading, the more anti-oxidizing it is. As such, a substance with an ORP reading of -400 mV is 4 times more anti-oxidizing than a substance with an ORP reading of -100 mV.
