Solid Surface pH Measurement Pen "Astro pH Tester Pen"

A measuring pen that can easily measure the pH of solid surfaces such as paper and fabric.

The "Astro pH Tester Pen" is a pen that allows for easy measurement of the pH of solid surfaces such as paper and fabric. It is necessary to measure the pH of paper to prevent printing issues such as poor ink drying and preservation problems. However, measuring the pH by soaking the paper in water and testing the extract with a pH meter can be time-consuming and labor-intensive, which is why the "Astro pH Tester Pen" was developed. 【Features】 ■ pH measurement can be performed simply by lightly applying the reagent to paper or fabric. ■ Its pen shape makes it portable, allowing for easy measurement on-site. ■ No power supply is needed, and there is no requirement for electrode maintenance or calibration. ■ Available in three types based on pH measurement range: * WS: pH 1.0–12.0, S5: pH 3.6–6.0, S7: pH 5.8–8.2 * For more details, please refer to the PDF document or feel free to contact us.
