GIDIGI CALIBRATION KIT: Complete ORP/pH meter calibration kit includes two 250mL bottles of 222mV redox buffer solution /pH7.00 calibration solution and 30mL ORP electrode storage solution and 2 beakers for measuring.
PRECISION/Both Purposes: Highly accurate redox buffer solution with ±0.05pH accuracy at 25°C (77°F) for reliable calibration of laboratory and industrial meters.Ensure accurate measurements with our ORP Redox Buffer 222mV Calibration Solution 250ml. It can calibrate ORP222 and pH7.0 at the same time, and one bottle can be used for both purposes.
LONG-LASTING SUPPLY: One bottle of our GIDIGI 222mV ORP calibration solution/pH7.0 buffer is 250 ml and the package includes 2 bottles of 220mv ORP solutions/pH 7 calibration solution, which can provide sufficient calibration times. Meanwhile, the GIDIGI store provides complete calibration test kits to save you time and money.
COMPATIBILITY: Universal buffer solution designed for use with all types of ORP meters calibration and 7.0 pH meters calibration for professional laboratory applications.
STORAGE-Room Temperature : The GIDIGI ORP buffer solution/pH buffer calibration kit requires storage at room temperature to help maintain solution stability and accuracy, ensuring consistent calibration results.
