Groline Nutrient Dosing System-Meter and probe - HI981413

GroLine HI981413 is an advanced nutrient dosing system designed for hydroponics and greenhouse growers requiring precise and automated management of nutrient solutions. With an integrated meter and industrial-grade probe, it continuously monitors and controls the concentration of nutrient solution (EC/TDS) in the reservoir.

• Automatic dosing is managed via a wall-mounted enclosure housing a built-in chemical dosing pump.
• Dosing can be configured for both on/off and proportional control, with adjustable set points ranging from 0.10 to 10.00 mS/cm (45 to 9900 ppm TDS, as per user-selectable factor).
• User calibration for EC and TDS is flexible, with one-point automatic and adjustable process methods.
• Temperature compensation and accuracy features provide reliable readings across a wide 0 to 50°C working environment.
• The intuitive backlit alarm system uses red, yellow, and green status lights for real-time awareness of system health.
• Galvanically isolated digital input and external outputs allow integration with external switches—for example, to pause dosing on low reagent conditions.
• Startup delay, overtime protection, and dosing hysteresis features safeguard crops against misdosing.
• The IP65-rated enclosure resists dust, water, and humidity, ideal for agricultural and horticultural installations.
• Suitable for industrial hydroponics operations, greenhouses, agricultural R&D, vertical farms, and nutrient solution management in controlled environment agriculture (CEA).
