TDS Pen-Type Tester

The TDS pen-style detector measures the total dissolved solids content in water using a conductivity sensor. When the electrodes come into contact with a water sample, they generate an electrical signal, which is then converted into a TDS value. It is commonly used for quickly testing the purity of drinking water and industrial water, as well as for verifying the effectiveness of water purifiers and monitoring water quality.
Selection
When selecting, ensure the measurement range covers common water quality levels of 0-1000 ppm, with accuracy error controlled within ±2%. It should have automatic temperature compensation. The housing must be waterproof and shockproof, with easily replaceable button batteries. Calibration solutions and user manuals should be fully included and compatible.
