Portable Water Quality Tester Pen for EC/TDS/Temperature

Dimension

Details

Q1: What is a good TDS reading for drinking water?
A1: A good Total Dissolved Solids (TDS) reading for drinking water typically falls between 50 and 300 parts per million (ppm). Water with TDS levels within this range is generally considered safe and palatable, providing a balance of essential minerals without affecting taste or quality. While the World Health Organization (WHO) suggests that water with TDS levels below 300 ppm is acceptable, levels below 50 ppm may lack necessary minerals, and readings above 300 ppm can indicate excessive impurities or high mineral content, which could affect the taste and potentially pose health concerns over long-term consumption.

Q2: What parameters can a water quality tester measure?
A2: A water quality tester can measure several key parameters to assess the safety and purity of water. Common measurements include Total Dissolved Solids (TDS), which indicates the concentration of dissolved substances like minerals and salts; Electrical Conductivity (EC), which reflects the water’s ability to conduct electricity and indirectly shows the level of ionized substances; and pH levels, which determine the acidity or alkalinity of the water. Some testers also measure temperature, as it can affect other readings, and dissolved oxygen (DO), which is critical for aquatic life. Additionally, advanced testers may monitor turbidity, chlorine levels, and specific contaminants like nitrates or heavy metals. These parameters together give a comprehensive overview of water quality.

Q3: How to calibrate water quality tester?
A3: Calibrating a water quality tester is essential for ensuring accurate measurements. The calibration process typically involves using standard solutions with known values for the specific parameters you intend to measure, such as pH, TDS, or EC. Start by rinsing the electrode or probe with distilled water to remove any contaminants. Then, immerse it in the calibration solution that corresponds to the parameter being calibrated. For pH meters, you may need to use multiple standard solutions (commonly at pH 4.00 and 7.00) to create a calibration curve. Follow the manufacturer's instructions to set the meter to recognize these values, usually by pressing a calibration button and allowing the device to adjust to the known readings.

Tips: Can I use the portable water quality tester pen for drinking water?
Yes! You can use the Portable Water Quality Tester Pen to check tap water, bottled water, filtered water, or other drinking sources. It helps you quickly see if the water is clean and safe by measuring TDS, EC, salinity, and temperature.
