These meters feature a large LCD that displays Multiparameter pH, EC, TDS, or temperature readings along with tutorial instructions. The pH readings are shown with a 0.1 resolution and an accuracy of ±0.1 pH while the EC and TDS readings are displayed with a 10 m/s/cm and 10 ppm (mg/L) resolution and 2% full-scale accuracy. Please select the meter with the range you require for your testing.
The temperature correction coefficient (β) is fixed at 2%/°C and allows for automatic temperature-compensated measurements of EC and TDS. These meters are calibrated manually to a single point with the use of two trimmers. pH is calibrated to 7.01, while EC/TDS is calibrated to 1.41 mS/cm (1413 µS/cm) or 1500 PPM. The LCD screen has a battery life indicator as well as on-screen tutorial messages.
No probe changes are required when switching your measured parameter between pH, conductivity, and TDS. These multiparameter meters reduce the number of instruments required for daily water quality analysis.
The supplied probe on all models features a polypropylene body, an amplified pH electrode with a built-in EC/TDS, and temperature sensors. The amplifier for the pH electrode prevents interference from humidity and electrical noise from common sources including the motors, ballasts, or pumps. Click Here for More Information
