Methyl Violet Test Strips, Narrow Range pH 0.2-2.0, 100-Vial

This vial of 100 Methyl Violet test papers is used to test strong acid solutions and detect nitrogen oxides in vapors. The papers are calibrated to accurately measure pH within a narrow range of 0.2 to 2.0, transitioning from violet at pH 2.0 to yellow at pH 0.2. Each strip measures approximately 48 mm long and 6 mm wide (1.875 x 0.25 inches). The narrow pH range makes these papers particularly useful for monitoring and confirming strong acid concentrations in laboratory settings.
