TDS Water Quality Tester DM1/DM2 — Dual Probe HD LCD TDS/EC/PH Meter for Drinking Water, Pool & Aquarium (Portable)

Portable dual-probe water tester DM1/DM2 for quick, reliable checks of drinking water, pools and aquariums. The unit features an HD LCD for clear readouts and a dual-probe arrangement that covers TDS and PH/EC measurements. The DM-1 probe reads TDS from 0.00 to 9990PPM and automatically multiplies readings by 10 when values exceed 999PPM. The DM-2 probe measures EC (Electrical Conductivity) across a range of 0 to 9990us. Measurement detail: 1PPM resolution for 0-999PPM and 10PPM resolution for 1000-9990PPM, giving precise values across low and high TDS ranges. Power is supplied by either 2*1.5V button batteries or 2*AAA batteries (not included), allowing flexible battery options. For installation and placement the tester includes an extension cord of approximately 63CM or 117CM and supports multiple mounting methods such as Ve-lcro attachment and a hanging plate.
