The A150 and A151 Professional Conductivity/TDS/Salinity Meters are advanced instruments for measuring conductivity, TDS, salinity, resistivity, and temperature. Featuring 1-5 point push-button calibration, automatic solution recognition, and selectable cell constants, these meters offer highly accurate and customizable readings. With Automatic Temperature Compensation (ATC) and alarms for out-of-range readings, they ensure precision across various solutions. The A150 also includes Conductivity Ash measurement. Both models have memory for up to 1000 readings, USB data transfer, and optional electrodes for low or high conductivity solutions. Ideal for labs and fieldwork, they offer versatile, reliable performance.
AELAB A150/151 meters operate using advanced electrochemical sensing. The user connects a conductivity electrode with a selectable cell constant suited for the solution range. The instrument uses Automatic Temperature Compensation (ATC) and intelligent algorithms to correct readings to standard reference temperatures. Users can calibrate using up to five standard solutions for pinpoint accuracy. With user-adjustable parameters like TDS conversion factor and temperature coefficients, the system adapts to diverse testing needs while maintaining consistency and precision.
