The Groline Waterproof Portable pH/EC/TDS Meter HI9814 by HANNA Instruments is designed to bring simplicity to nutrient testing. This Portable GroLine Meter is designed specifically for Hydroponic growers. The specialized electrode combines 3 sensors in a single rugged probe featuring a polypropylene body, integrated temperature sensor, and cloth junction.

  • One combined, pre-amplified pH, EC, and TDS (ppm) probe for hassle-free measurements.
  • Quick CAL mode for a speedy, single-point calibration for pH and EC with one solution.
  • Designed for hydroponic, aquaponic, and greenhouse growers.

The included batteries provide 600 hours of continuous use. When the battery level is below 10%, a warning symbol will blink to indicate low battery condition. When low battery power may affect your results, the meter will shut down to avoid erroneous readings caused by low battery level.

An on-screen indicator provides visual confirmation that your probe is working at its best. The auto-off feature can be set to shut the meter off at 8 or 60 minutes, or it can be disabled so that the meter continuously stays on. The auto-off feature prolongs battery life for peace-of-mind and energy savings if the meter is accidentally left on.

The pH sensor in the probe is a single junction electrode with gelled electrolyte and a retractable cloth junction. When readings appear sluggish, simply pull out some of the cloth material to renew the junction with a fresh surface.

The EC/TDS portion is a two-ring probe that comes with the HI9814, offering an accurate solution for low range EC and TDS readings. An integrated temperature probe ensures fast, accurately compensated readings even during sudden temperature fluctuations.

The GroLine Combo Meter comes with cleaning solution that has been engineered to keep your electrode free from debris found in soils. This concentrated combination of detergents cleans your meter quickly and effectively so that your meter stays in optimum condition.
