GroLine Combo pocket instrument for pH / EC / TDS /
GroLine Combo is a slim, lightweight, and waterproof pocket meter that measures pH, conductivity (EC), total dissolved solids (TDS) and temperature. The operation of the instrument is simplified with only two buttons: one for on / off and for calibration, the other to change the measurement mode. The meter is equipped with advanced features, such as selectable EC to TDS conversion factor (0.5 - 500 ppm and 0.7 - 700 ppm).
The pH measurements are displayed with a resolution of 0.01 and an accuracy of +/- 0.05 pH, while the EC and TDS measurements are displayed with a resolution of 0.01 mS / cm and 10 ppm (mg / L) and an accuracy of 2% f.s. The HI98131 EC scale is from 0.01 to 6.00 mS / cm and TDS from 0 to 3000 ppm using conversion factor 0.5. The meter also offers the option to use an EC / TDS conversion factor of 0.7 (700 ppm).
The instrument's temperature sensor allows for fast temperature compensated EC and TDS measurements. The display shows indicators for calibration and stability. The battery charge percentage is displayed when the instrument is started. It is a versatile pocket tool designed for applications in hydroponics, greenhouses and agriculture.
