Hanna HI981412-20 GroLine pH dosing system

Hanna HI981412-20 GroLine pH dosing system

The Hanna HI981412-20 GroLine pH Dosing System is an advanced, inline pH control system designed for precise and continuous pH monitoring in nutrient solutions. Ideal for hydroponics, fertigation, and greenhouse environments, this model features a rugged industrial-grade electrode with AmpHel® reference technology and a quick-connect DIN connector for fast installation and reliable signal transmission.

With chemical-resistant PVDF housing and a maximum pressure rating of 3 bar (43.5 psi), the system is built to perform in high-demand and pressurized fluid applications.

Features

• Wide pH Range for Nutrient Monitoring
  Measures pH from 0 to 12, ideal for maintaining balanced nutrient solutions in agricultural systems.

• Durable Industrial Electrode Design
  Features a double junction reference and cloth junction to reduce clogging and extend sensor life in nutrient-rich environments.

• Integrated Temperature Sensor
  Enables automatic temperature compensation, ensuring accurate pH readings regardless of thermal variation.

• AmpHel® Technology and Matching Pin
  Built-in AmpHel® system enhances signal stability, and the matching pin reduces ground loop interference in electrically noisy systems.

• Strong, Chemical-Resistant Housing
  Made from white PVDF, ideal for agricultural, industrial, or chemical environments where durability is essential.

• Flexible Inline Installation
  Includes two threaded mounting options:

  • Top Thread: ¾” NPT

  • Inline Thread: ½” NPT

• Quick-Connect DIN Connector
  Ensures secure, tool-free probe connection and easy integration into controller units.

• Long Cable Length for Flexible Setup
  Comes with a 2-meter cable for convenient routing and installation.

• High Pressure Tolerance
  Rated for up to 3 bar (43.5 psi) at 25°C, suitable for pressurized irrigation and nutrient systems.
