The ADWA AD32 EC and TDS meter is a digital gardening EC and TDS meter. Continuous conductivity measurement can be used to determine exactly how much nutrient a given plant needs. Thus, its use can make the environment specifically economical and healthier for plants.

Main characteristics

• automatic temperature compensation
• replaceable electrode (long life)
• automatic shut-off
• dual line LCD display
• automatic shut-off function (protects against battery discharge)
• can be calibrated at one point (this requires EC calibration fluid)
• indication of the battery charge level (facilitates the time of possible battery replacement)
