The pH 4.01 calibration buffer from the DURACAL series is a reference solution for calibrating pH electrodes in the acidic range, essential for multi-point calibration of measuring probes.
The unique composition with a preservative additive guarantees five-year retention of the precise pH value and immunity to contamination by microorganisms.
Regular calibration of the pH electrode using the pH 4.01 and pH 7.00 buffers ensures linear measurement accuracy across the entire operating range of pool water and enables early detection of electrode wear.
The buffer is designed so that only the minimum necessary amount is used, which reduces the cost of repeated calibration throughout the entire pool season.
