Probe Condition

An on-screen indicator provides visual confirmation that your probe is working at its best.

Low Battery Indicator

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.

Automatic Shut-off

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.

Built to be Durable

Designed to withstand the knocks, drops, and spills of real life, the new IP67 body ensures top performance in any environment. These meters are protected against dust and water intrusion from any direction.

Portable Design

Made to fit comfortably in your hand for on-the-go testing, the multilevel LCD display provides at-a-glance pH, EC/TDS, and temperature measurements from any angle and dual button operation streamlines the testing process for any user.

Quick Connect Probe

A Quick Connect DIN connector makes attaching and removing the probe simple and easy. The rubber coating protects the cable and provides a water-tight seal without twisting.

Your measurements require detailed attention; so should your electrode. The HI9814 Portable GroLine Meter features a replaceable HI1285-7 probe that has been carefully designed specifically for the pH, EC, and TDS analysis of hydroponic nutrient solutions.

Polypropylene Body

The polypropylene body of the HI11285-7 houses all three sensors within a sturdy, single body design. The plastic body protects the electrode from damage, is easy to clean, and is chemically resistant to many aggressive chemicals.

Pre-Amplified pH Electrode

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.

Amperometric EC/TDS Sensor

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.

We believe that buying a meter should be simple. Your Portable GroLine Meter is equipped with everything you need for successful testing right out of the box.

Quick Calibration Solution Sachets (3)

A single calibration solution for pH and conductivity makes calibration fast and ensures all of your measurements are accurate each time for better plant health and better yield. The single-use sachets are individually sealed so you use fresh buffer each time you calibrate.

Electrode Cleaning Solution for Agricultural Applications Sachets (3)

Your 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
