TDS meter

The pictured device is a Total Dissolved Solids (TDS) meter, used to measure the total amount of dissolved substances in water. Here's some helpful information:

• Function: It measures the electrical conductivity of water to estimate the concentration of dissolved solids in parts per million (ppm). 

• Range and Accuracy: It typically measures from 0-9990 ppm with an accuracy of ±2%. 

• Usage:

• Remove the cap and turn the meter on. 

• Place the probe into the water, and wait for the reading to stabilize. 

• The reading indicates the TDS level in ppm. 

• TDS Levels:

• 0-50 ppm: Ideal for drinking. 

• 50-150 ppm: Acceptable drinking water. 

• 150-300 ppm: Hard water, safe but may cause scaling. 

• 300-500 ppm: Not ideal for drinking. 

• Above 500 ppm: Not safe for drinking, requires purification. 

• Limitations: Does not measure pH levels. 

• Maintenance: Clean the probe after use and replace the cap.
