Designed for professional use, this test kit falls under the category of labware measuring instruments and test systems. It specifically serves the purpose of verifying pH levels within the range of 5.0–9.0. The kit includes a sample container marked with a 5ml ring, dropper bottles or powder flasks containing the necessary reagents, and a dosing spoon for powder reagents. Additionally, it comes equipped with a color chart for easy interpretation of results. This kit's gradation spans from pH 5.0 to 9.0 in increments of 0.5, allowing for 200 measurements. The reagents have a boiling point of 78°C and a melting point of -114°C.
