The Hanna GroLine pH/EC/TDS/Temperature Meter is a lightweight, waterproof portable pH, conductivity, TDS and temperature meter that comes with a specialist multi-parameter probe for hydroponics, greenhouse and agricultural applications.

Hanna GroLine pH/EC/TDS/Temperature Meter Key Features:

• Compact, robust casing
• Simultaneous readout of pH, EC or TDS and °C
• Simple two button keyboard
• Waterproof design to withstand the humidity of a growing environment
• Specialist multi-parameter electrode
• Optional green protective rubber holster – HI-710025

The HI-9814 boasts many advance features that you usually find in more expensive portable meters. Features including automatic calibration, buffer/standard recognition and temperature compensation. The large multi-level LCD display shows on-screen tutorial messages and indicators for the calibration status and stability.

Specialist multi-parameter electrode for hydroponics

The HI-1285-7 multi-parameter electrode overcomes issues of measuring pH & EC/TDS in hydroponic applications. Issue such as those associated with aggressive chemicals, frequently faced by conventional multi-parameter electrodes.

The HI-9814 is supplied complete with the HI-1285-7 specialist electrode that features the following key benefits:

• Pre-amplified pH electrode – prevents interference from humidity and sources of electrical noise including circulating pumps, motors and ballasts from grow lights.
• Amperometric EC/TDS sensor – EC/TDS readings are performed by a two-pin amperometric sensor, best suited to low conductivity applications
• Built-in temperature sensor – readings of pH and EC/TDS must be temperature compensated in order to obtain accurate results. The built-in temperature sensor provides a speedy temperature reading which is then used to adjust the pH and EC/TDS results accordingly for higher accuracy.
• Polypropylene body – the durable body of the HI-1285-7 electrode is chemically resistant to many aggressive chemicals used in hydroponics and protects all three sensors.
• DIN Connector – the HI-1285-7 has been specifically designed for use with the HI-9814 meter, the DIN connector means the probe is not interchangeable.
