PH test pen
Features of PH test pen
1. Glass Bubble Probe
The PH test pen uses a glass bubble probe, which is made of a special
glass material and is highly sensitive to the concentration of hydrogen
ions in water. By accurately measuring the potential changes on the
electrode surface, it can accurately reflect the PH of the water sample
and ensure the accuracy of the measurement results.
The glass bubble probe is precisely processed and calibrated to maintain
stable measurement performance under various environmental conditions.
In addition, the probe surface is covered with a protective film, which
can effectively prevent the adhesion of pollutants and reduce
measurement errors.
The probe has the characteristics of fast response and can react with
the hydrogen ions in the water sample in a short time to reach a state
of equilibrium. This means that users can obtain accurate measurement
results in a short time and improve work efficiency.
2.LED LCD display
The PH water quality test pen is equipped with a high-definition LCD
display that can clearly display the measurement results. The numbers
and symbols on the display are optimized and can be easily read even in a
dimly lit environment. In addition to displaying the pH value, some
advanced models of PH water quality test pens can also display other
relevant information, such as battery power, calibration status, etc.
This information helps users better understand the working status and
measurement results of the device.
The operation interface on the display is simple and clear, and users
can view the measurement results or perform other operations with just a
tap. This design makes the PH water quality test pen easier to use and
suitable for various customer groups.
3. Hanging buckle design
The PH water quality test pen adopts a lightweight design and is
equipped with a hanging buckle, which is convenient for customers to
hang it around their waist or bag. This design allows customers to take
out the test pen for measurement at any time when needed, without
worrying about the loss of the equipment or inconvenience in carrying.
Because the PH water quality test pen is portable and responsive, users
can measure water quality at any time and place. This ready-to-use and
test function allows users to detect and deal with water quality
problems in a timely manner to ensure water quality safety.

Composition of PH test pen
The HP water quality test pen consists of a battery compartment, a display screen, a probe compartment, a calibration potentiometer switch, a hanging buckle, etc., as follows:
