Keep water quality in check with a compact 3in1 TDS/EC/temperature meter. It delivers reliable, quick readings for everyday use. Accurate, fast results: measures TDS (total dissolved solids), EC (conductivity) and temperature with automatic temperature compensation; typically ready in about 5 seconds. Power efficient: autooff after 9 minutes of inactivity to extend battery life. Flexible operation: four measurement modes; use SHIFT to switch modes; mode memory restores the lastused setting on startup. Easy logging: large LCD for clear readings; HOLD to lock the current value; data storage to help record results; press SHIFT while holding to view results for other modes. Practical design: compact, lightweight, built for home testing, labs, aquariums, hydroponics and field use. Use scenarios: Check drinking water quality at home or in the office. Monitor aquarium or hydroponic nutrient solutions to ensure conditions. Assess pool or spa water quality before use.
