Product Description
Aquatic Life TDS Tester Pen
Aquatic Life TDS Tester Pen is a handheld total dissolved solids meter for quickly checking source water, RO water, RO/DI output, aquarium preparation water, and other water-quality applications.
Aquatic Life TDS Tester Pen for RO/DI and Aquarium Water Checks
This compact TDS meter helps aquarists monitor how much dissolved material remains in water before and after filtration. It is especially useful for checking tap water, RO membrane performance, DI resin exhaustion, and final water quality before mixing saltwater or using top-off water.
Handheld TDS Meter with Hold Function and Auto-Off Display
- Measures total dissolved solids from 0-999 ppm.
- Reads in 1 ppm increments.
- Accuracy listed by J&L as ±2% using microprocessor technology.
- Hold function freezes the reading for easier recording.
- Auto-off powers down after 5 minutes to help save battery life.
- Large LCD display provides a clear readout.
- Useful for RO/DI systems, aquarium water preparation, source-water checks, and filter troubleshooting.
Aquatic Life TDS Tester Pen RO/DI Monitoring Notes
Use the TDS Tester Pen to compare source-water TDS, RO-only output, and final DI output. Rising TDS after the membrane may indicate reduced membrane performance, while rising TDS after DI usually means the resin is exhausted and should be replaced. TDS does not identify the specific dissolved substances present; it shows the total dissolved solids level.
Aquatic Life TDS Tester Pen Directions
- Remove the cap and turn on the meter before testing.
- Rinse the probe with clean water before taking a reading.
- Dip the probe into the water sample without submerging the entire meter.
- Wait for the reading to stabilize on the LCD display.
- Use the hold function if you need to freeze the reading for recording.
- Rinse and dry the probe after testing.
- Store the tester capped and dry between uses.
