This meter features a large LCD which displays either pH, EC, TDS or temperature readings along with tutorial instructions. The pH readings are displayed with a 0.1 resolution and an accuracy of ±0.1 pH while the EC and TDS readings are displayed with a 0.01 mS/cm and 1ppm (mg/L) resolution and 2% full scale accuracy. The EC range of both meters is from 0.00 to 4.00 mS/cm and TDS is from 0 to 1999ppm. The temperature correction coefficient (?) is fixed at 2%/°C and allows for automatic temperature compensated measurements of E and TDS. This meter is calibrated manually to a single point with the use of two trimmers. pH is calibrated to pH 7.01 while EC/TDS is calibrated to either 1.41mS/cm or 1500ppm. The LCD screen has batter life indicator as well as on-screen tutorial messages. No probe changes are required when switching your measured parameter between pH, conductivity, and TDS.
This multiparameter meter reduces the number of instruments required for daily water quality analysis. The supplied probe features a polypropylene body, 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 from motors, ballasts, or pumps.
