Portable Pen-Type Acidity Meter

The portable pen-type pH meter utilizes an electrochemical system composed of a glass electrode and a reference electrode to measure the potential difference generated by hydrogen ion activity in a solution, which is then converted into a pH value through circuitry for display. It is used for on-site rapid detection of liquid acidity or alkalinity, suitable for scenarios requiring immediate readings such as water quality monitoring, food processing, and chemical reactions.
Selection
When selecting, consider a measurement range that covers the common pH range of 0–14, with an accuracy of ±0.1 pH and automatic temperature compensation. Check the replaceability of the electrode and the convenience of calibration. The device body should meet the IP67 waterproof rating. Pay attention to battery life and data storage capacity, and ensure that the accompanying calibration solutions are complete.

Articles

Pencil hardness tester rapidly evaluates scratch resistance of paint film.
This article introduces how to quickly assess the scratch resistance of paint films using a pencil hardness tester. During the test, standard pencils (ranging from 6B to 9H) are used to scratch the coating at a fixed angle and pressure to observe whether scratches occur.
Dyne Pen Selection, Surface Energy Test Range, and Pen Tip Lifespan
The dyne pen is used to evaluate the wettability of material surfaces, reflecting the effectiveness of treatments by measuring surface energy.
Pencil Hardness Tester for Rapid Evaluation of Coating Surface Hardness
The pencil hardness tester is a tool used for rapidly assessing the relative hardness of coating surfaces through standardized scratch tests. It employs a series of pencil leads with known hardness levels, which are drawn across the coating under a fixed load and angle. The hardness grade, ranging from 6B to 9H, is determined based on whether a permanent scratch is produced.
Pencil Hardness Plan Outstanding Paint Film Pencil Hardness Grade
The pencil hardness test is a method for evaluating the scratch resistance of paint films. It involves using a series of pencils with known hardness levels to scratch the coated surface under fixed conditions. The hardness grade of the coating is determined by observing whether permanent scratches are produced.
Application of Film Pencil Hardness Tester in Coating Scratch Resistance Testing
The paint film pencil hardness tester is an instrument used to evaluate the scratch resistance of coatings. It works by scratching the surface of the coating with a pencil of known hardness under a fixed load, and then assessing the hardness grade based on whether scratches are produced.
Classification standards for determining the hardness of coatings using a pencil hardness tester.
This article introduces the method of measuring the hardness of coatings using a pencil hardness tester. It involves using pencils of varying hardness to scratch the coating and observing whether scratches are produced to determine the hardness grade, ranging from 6B to 9H.
Key Operational Points and Influencing Factors of Pencil Hardness Method for Determining Coating Film Hardness
The pencil hardness test is a method used to evaluate the scratch resistance of a coating by making marks on the paint film with pencils of known hardness. During the operation, a uniformly cured sample is prepared, and calibrated pencils are used to make marks at a 45-degree angle with a fixed force, aiming to identify the highest hardness grade that does not scratch through the paint film.
How to Select a Pencil Hardness Tester? A Comprehensive Guide from Principles to Practical Application
When selecting a pencil hardness tester, focus on three key points: choose manual or automatic based on standards, use specialized testing pencils, and ensure the instrument can fix a 45-degree angle for uniform force application to achieve accurate and reliable results.
