Vitalink Essentials PH EC Buffer 4 7 & CF Calibration
Regular price
£4.00
Use VitaLink ESSENTIALS Buffer solution to calibrate pH meters.
This pH 4 Buffer solution gives an accurate representation of the pH scale at pH4 to measure against.
Use VitaLink ESSENTIALS Buffer 7 for a 2 point calibration scale.
This will give an accurate range of measurement that hydroponic nutrients work within.
Perfect for use with the ESSENTIALS pH meter
Use ESSENTIALS calibration solution to calibrate EC/CF meters. Set to read CF28 at room temperature.
NOTE: All calibration solutions should be at room temperature (20°C) for successful and accurate calibration. Use with ESSENTIALS EC Meters.
