Amprobe Amprobe WT-20 Conductivity/TDS Pen-Type Water Quality Meter

The Amprobe WT-20 Conductivity/TDS Pen-type Water Quality Meter measures the conductivity, total dissolved solids (TDS), and the temperature of water, and is used to troubleshoot corrosion and to test water in wastewater treatment facilities, labs, pools, aquariums, car washes, and aquaculture. The dual-display LCD screen simultaneously displays either conductivity and temperature or TDS and temperature. One-touch auto-calibration provides for in-field calibration, and requires no additional tools. The TDS factor can be adjusted from 0.4 to 1.0. The hold function saves the reading for recording. The auto power off feature turns the meter off after 20 minutes, and can be disabled for readings that require more time. The meter has a replaceable pH electrode, requires four A76 or LR44 batteries (included), and includes instructions. Specifications Conductivity range 0 to 1,999 uS (0 to 19.99 mS) TDS Range 0 to 1,999 ppm (0 to 19.99 ppt) Resolution 1 uS (0.01 mS) or 0.01 ppt (1 ppm) Accuracy + or - (1 percent...
