Product Information
The analyzer consists of an LCD display instrument and a Germany-made P9.3 PAA sensor adopting a membrane-covered amperometric 2-electrode system to accurately measure PAA concentration in aqueous solutions. It delivers temperature-compensated analog signals and Modbus RTU digital signals, supports calibration via downstream devices and direct connection to dedicated transmitters with one-key calibration. Features include high-temperature tolerance (up to 60℃ water temperature), chemical/surfactant-resistant elastomer membrane, acid conductivity tolerance, <2%~3% accuracy (for 2000 mg/L range), T90 response time 45s~3.5min, flexible connectivity and IP65/IP68 protection, is EMC/RoHS compliant, requires minimal maintenance, and is ideal for water treatment in electroplating, pharmaceutical, food and beverage, dairy, and chemical industries (e.g., bottle washing machines, CIP plants).
