GroLine Quick Cal, pH and EC Calibration, Cleaning and Storage Solutions With GroLine Quick Cal solution only one solution is needed to calibrate both pH and conductivity. This dual-purpose calibration solution is used with compatible meters with the Quick Cal mode or with pH and conductivity meters that calibrate to pH 6.86 and 5.00 mS/cm, respectively. See page 2.139 GroLine also includes pH (See page 2.139) and conductivity (See page 5.34) solutions in 120 mL and 250 mL bottles. Maintaining a clean pH electrode is vital for not only in getting an accurate pH measurement but also ones that are drift free. Any coating to the sensitive glass bulb or clogging of the junction will impede the electrical circuit resulting in erratic and misleading readings. GroLine cleaning solution ensures the maximum performance from the pH electrode to provide readings that you can depend on. See page 2.143 All glass pH electrodes need to be stored properly to guarantee an accurate calibration and to protect the pH electrode frompremature failure. A few drops of storage solutionwill maintain the hydrated layer on the glass bulb and prevent the reference junction and electrolyte from drying out. GroLine storage solutions are specifically formulated to accomplish the task and maximize the life of the pH electrode. See page 2.144

HI98331 Soil Test™ GroLine Soil Test

Direct Soil EC and Temperature Meter with Built-in Stainless Steel EC Probe The GroLine Soil Test EC (conductivity) and temperature tester offers many advanced features for growers of all types. The Soil Test offers automatic one-point calibration, stability indicator, hold functions to freeze readings on screen, lowbattery indicator, and selectable automatic shut-off. With its compact size, single-button operation, and ease of calibration, Soil Test is the optimal tool for EC measurements made directly in soil.
