Clean Water Tester Pen, TDS, Conductivity 850068 - Sper Scientific

Clean Water Tester Pen, TDS, Conductivity 850068 by Sper Scientific (USA) is a compact handheld device specialized for testing drinking and domestic water quality. It quickly measures key parameters such as total dissolved solids (TDS), conductivity, and water temperature, supporting the assessment of water cleanliness and safety.

With a durable corrosion-resistant titanium sensor, automatic temperature compensation (ATC), and auto power-off when idle, the 850068 pen is very convenient for technicians, water treatment plants, or individual users concerned about water quality.

The device operates with a single button and features waterproof design to enhance durability and stability during measurement.

• Measures total dissolved solids (TDS) from 0 ~ 9,999 ppm with ±2% accuracy.
• Measures conductivity from 0 to 9,999 µS/cm with ±2% full-scale accuracy.
• Measures water temperature within 0 ~ 80°C range with 0.1º increments and ±2% accuracy.
• Automatic temperature compensation (ATC) for more accurate readings when sample temperature varies.
• Compact pen-style design for easy handheld use and operation.
• Titanium electrode sensor for corrosion resistance, enhancing durability and measurement stability.
• Single button operation for power on/off and measurement, suitable for all users.
• Auto power-off after 2 minutes of inactivity to save battery.
• Waterproof design protects the device when measuring water samples directly.

Reference TDS Levels (ppm):

• 0 ~ 70: safe water for the body, with 0 ~ 50 ppm ideal for drinking water.
• 50 ~ 100: spring water, groundwater filtered through carbon.
• 100 ~ 170: hard water.
• 200 ~ 300: mildly hard water.
• 300 ~ 500: highly hard water, not recommended for use.
• 500: polluted water, absolutely not recommended for use.

The 850068 clean water tester pen is widely used in areas such as:
