The Apera WS200 (AI4721) is a portable multiparameter water-quality meter measuring fluoride, pH, electrical conductivity (EC), TDS, salinity, resistivity, and temperature. Its three interchangeable probes support water-quality testing across cultivation facilities and laboratories. The fluoride probe measures directly without added reagents or sample stirring, and the system complies with EPA Method 340.2 for fluoride analysis.
