Product Description

The Amprobe WT-30 Salinity Pen-type Water Quality Meter measures the salinity and 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 salinity and temperature, and dual-scale temperature readings in F and C are user-selectable. The meter has a built-in NaCL temperature coefficient and TDS conversion factor. One-touch auto-calibration provides for in-field calibration. Normalization is fixed at 77 degrees F (25 degrees C).

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.
