Product Description

The GroLine HI981420 Nutrient Monitoring System for Hydroponics delivers precise, real-time readings of pH, EC, TDS, and temperature to optimize nutrient management in hydroponic, aquaponic, and greenhouse applications. Designed for ease of setup and daily operation, the HI981420 enables growers to maintain ideal growing conditions and ensure consistent yields season after season.

Continuous 24/7 monitoring of nutrient solution parameters for proactive cultivation management.
Large, backlit LCD clearly displays pH (0.00–14.00), EC (0.00–10.00 mS/cm), TDS (0–7,000 ppm), and temperature (0 – 60°C).
Automatic logging records the last 30 days of readings at 15-minute intervals, supporting GLP and traceability.
Settable high-low alarm relays with enable/disable for rapid correction of out-of-range conditions.
IP65-rated enclosure protects against water and dust ingress, ideal for greenhouse and agricultural environments.
Quick Cal solution compatible; calibrate both pH and EC in one step for fast, straightforward maintenance.
HI1285-8 pre-amplified polypropylene probe with internal temperature sensor and DIN/2 m cable ensures stable, reliable readings.
USB Type-C output for easy data retrieval to flash drives or compatible devices.
Automatic temperature compensation ensures precision under fluctuating environmental conditions.
Includes 12VDC power adapter for continuous operation.

Industrial Use: Ideal for commercial hydroponics, aquaponics, greenhouses, research laboratories, educational facilities, and agricultural production where controlled nutrient supply is critical.

Package Contents: 1 x GroLine Monitor HI981420 unit, 1 x HI1285-8 multi-parameter probe (pH/EC/TDS/temperature), 1 x 12VDC power adapter, Quick Cal calibration solution, user manual.
