Combined pH, EC, Temp indicator for agriculture

It enables continuous, 24-hour monitoring of pH, conductivity (EC and TDS) and T

The indicator for hydroponic applications, which enables continuous, 24-hour monitoring of pH, conductivity (EC and TDS) and temperature in hydroponic nutrient solutions.

Quick to set up, simple to use, this indicator is designed for hydroponics, aquaponics, soilless crops, and greenhouses. With this tool, nutrient solutions for your crops become easy to manage.

  • Visual alarm when upper and lower limits are exceeded
  • IP68 watertight probe that can be submerged continuously
  • Quick calibration function to calibrate pH and EC/TDS with a single solution
  • Data storage and transfer to USB flash drive or PC

A quick glance is all it takes to get everything under control.  A large backlit display simultaneously shows all essential parameters so you can evaluate your hydroponic nutrient solution, 24/7. High and low alarms flash if adjustment is needed.

Monitor changes over time. The instrument automatically records results every 15 minutes for the past 30 days. Minimum, maximum and average values are stored so that it can recognize when major changes occur, thus preventing future problems.

One probe. Three measurements. Our preamplified 3-in-1 probe measures pH, EC / TDS and temperature in a single durable polypropylene body. This makes installation and maintenance much easier.

Quick Cal Function for Quick Calibration. The use of a single calibration solution for both pH and conductivity makes the calibration procedure fast and ensures that all measurements are always accurate, resulting in better plant health and yield.

Instrument features. 

  • 3 sensors combined in one rugged probe: pH electrode with renewable fiber junction, amperometric sensor for EC/TDS, and integrated temperature sensor for readings with automatic temperature compensation
  • IP65 protection: designed for harsh environments
  • Wide pH scale: pH measurements from 0.00 to 14.00 pH
  • Selectable EC/TDS conversion factor: choice of 0.5 or 0.7 conversion factor
  • Automatic temperature compensation: all readings are automatically compensated for temperature changes, the value of which can be displayed in oC or oF, along with pH, EC or TDS readings
  • Large LCD display with backlighting: the LCD can simultaneously display all three essential measurements in hydroponics, for nutrient control; you can choose to display individual measurements (updated every 3 seconds) or a graphical
  • display, updated in real time, with options for selecting measurements and displaying stored readings
  • Data storage for 30 days: Values are stored every 15 minutes, including minimum, maximum and average values. Stored data are retained for 30 days.
  • Data transfer to PC: USB Type C port for transferring stored data to PC or USB flash drive
  • Minimum and maximum alarms: when your nutrient solution is out of the desired parameters, the display flashes
  • Ambient light sensor: for automatic backlight adjustment
