  • Page 8: Description

    4. DESCRIPTION 4.1. SIGNIFICANCE OF USE pH in agriculture pH affects the ability of plant roots to absorb nutrients. Calcium, phosphorus, potassium and magnesium are likely to be unavailable to plants in acidic soils. Plants have difficulty absorbing copper, zinc, boron, manganese and iron in basic soils. By managing pH, you can create an ideal environment for plants and often discourage plant pests at the same time.
  • Page 9 EC in agriculture EC stands for electrolytic conductivity, or the ability of a solution to conduct an electric current. Current travels efficiently through water with high levels of salt present (high EC), and less so through pure water (low EC). EC indicates how much dissolved salt is in a given sample. That's why EC is also referred to as TDS (total dissolved solids).

  • Page 10: General Description

    4.2. GENERAL DESCRIPTION GroLine Monitor is designed to offer you the combination of pH, conductivity, (or total dissolved solids), with temperature measurements. All operations and settings, including calibration buffers and temperature scale selection, are included in easy to use monitor setup. The supplied HI1285‑8 multiparameter probe measures pH, EC/TDS, and temperature in one...

    5. GENERAL OPERATION 5.1.START UP MONITOR This is a general outline of the steps required to perform accurate measurements: 1. Mount the monitor on a stable support/wall. 2. Connect the HI1285‑8 probe to the monitor. 3. Connect the power adapter to the monitor and power source. 4.

  • Page 14: Probe Connection

    GroLine Monitor and probe can be used for fertilizer tank monitoring. The system continuously measures the EC and pH of the tank. The probe (HI1285‑8) should be placed in location representing the bulk properties of the tank. 5.2.

  • Page 15: Electrode Conditioning And Maintenance

    5.3. ELECTRODE CONDITIONING AND MAINTENANCE During transport tiny bubbles of air may have formed inside the pH sensor bulb. The electrode cannot function properly under these conditions. These bubbles can be removed by “shaking down” the electrode as you would do with a glass thermometer. If the pH bulb and/or junction are dry, soak the probe in HI70300 Storage Solution for at least one hour.
  • Page 16 EC Cell cleaning and Inspection 1. On a weekly basics, rinse the probe with tap water as preventative maintenance. Monthly, a more thorough cleaning is advised. Clean the EC sensor (slot in bottom of probe) with a non‑abrasive detergent, or see #4 below. 2.
