GroLine Combo pH/EC/Temperature Tester

GroLine Combo pH/EC/Temperature Tester


Introducing the GroLine Combo pH/EC Tester, a sleek, portable, and waterproof pocket tester engineered to measure pH, conductivity, TDS, and temperature. This adaptable meter is tailor-made for hydroponics, greenhouse, and agricultural applications.

Operating the meter is straightforward, with just two buttons€”one for power and calibration, and the other for switching between measurement modes. The GroLine Combo pH/EC Tester boasts advanced functionalities, including a customizable EC to TDS conversion factor (ranging from 0.5 to 500 ppm and 0.7 to 700 ppm).

The GroLine Combo pH/EC Tester showcases a large, multi-level LCD screen that simultaneously displays pH, EC or TDS, and temperature readings. pH readings are shown with a 0.01 resolution, while EC and TDS readings exhibit a 0.01 mS/cm and 10 ppm (mg/L) resolution, respectively.

Featuring an exposed temperature sensor, it enables quick temperature-compensated measurements of EC and TDS. The LCD screen also provides indicators for calibration status and stability, along with displaying the remaining battery power percentage at startup.
