Attention Valued Customer:
Ph testers and Ph probes are sensitive scientific equipment. They will require extra care and maintenance from the user (you) to ensure accurate readings, measurements and valid warranties.
Ph testers (without replaceable probes) and Ph probes are electrical sensors and considered a consumable item. You should aim to be replacing these over time as you do media, nutrients, etc. Probes and Pens (without replaceable probes) only have a 6-month warranty from date of purchase and will not be honoured without receipt of purchase.
Probes and Pens with proper care can last for years, but as it is a live charge in the electrode it can be finished from 6 months. Moreso if correct care procedures have not been maintanined. Hydroponic nutrients in particular degrade Ph probes much faster than other disciplines.
Probes must always be rehydrated before use in storage solution, available for purchase in store
Probes must be kept in storage solution when not in use (in tank monitors excepted)
IF IT DRIES….IT DIES
Please read the entire contents of the booklets and handouts that come with all PH instruments carefully.
The HI981420 GroLine Monitor for Hydroponic Nutrients provides around-the-clock, continuous monitoring of pH, conductivity (EC & TDS), and temperature in hydroponic nutrient solutions.
Quick to setup, simple to use, this monitor was designed with Hydroponics, Aquaponics, and Greenhouses in mind. Make your nutrient solution easy to manage with the GroLine Monitor.
- Get 24/7 pH&EC measurements for consistent yields every time.
- Good Laboratory Practice (GLP) feature for professional accuracy.
- Calibrate pH and EC with a single Quick Cal solution.
One quick glance is all it takes.
A large clear LCD displays all of your essential readings so you know what your hydroponic nutrients solution is doing 24/7. High and low alarms flash warning you if something needs adjusting.
Monitor changes over time.
The GroLine Monitor automatically logs your results every 15 minutes over the last 30 days. Minimum, maximum, and average values are stored so you can recognize when patterns arise and help prevent future problems.
One probe. Three measurements.
Our 3-in-1 pre-amplified probe measures pH, EC/TDS, and temperature in a single, durable, polypropylene body making the GroLine Monitor easy to handle and easy to set up.
Quick Cal for less maintenance.
A single calibration solution for pH and conductivity makes calibration fast and ensures all of your measurements are accurate all of the time for better plant health and better yield.
