HY-GEN PH UP 1 LITRE

Conductivity 2.76 It is essential to calibrate your EC (electrical conductivity) meter with CONDUCTIVITY 2.76 solution regularly. The measurement of available nutrients in the solution is measured as electrical conductivity. The units used to report the readings are millisiemens per centimetre (mS/cm), Conductivity Factor (cF), or parts per million (ppm). The conductivity increases with nutrient strength. Distilled or deionized water will give a near-zero reading. As a general guide for hydroponics: 1mS/cm = 10cF = 700ppm. Nutrient requirements vary from plant to plant; therefore the ideal conductivity varies from plant to plant also.
SOLUTIONS SCIENTISTS USE HY-GEN Calibrations solutions are made according to international standards.
The pH ELECTRODE STORAGE and PROBE CLEANER solutions are the same quality as those used in laboratories for the safe cleaning and storage of electronic meters.
All calibration and care solutions are made using high-quality analytical grade constituents.
