The pH 7.00 calibration buffer from the DURACAL series is developed with an innovative composition that ensures unprecedented long-term stability of the pH value.
The guaranteed shelf life of the buffer is 5 years from the date of production, which significantly reduces the cost of regularly purchasing new calibration solutions.
The addition of a preservative protects the solution from the effects of bacteria and mould, so the buffer retains its calibration accuracy throughout the entire warranty period.
Using this buffer when calibrating the electrodes of ASIN AQUA measuring systems guarantees a fast and stable sensor response and thus precise measurement of the pH of pool water.
