TDS-4TMA: Aquarium TDS Meter with Digital Thermometer
Measures TDS and salt levels of freshwater up to 9990 ppm.
- Includes an internal digital thermometer (celsius only).
Hold Function - Locks the reading on the screen outside of the water.
Auto-off function - Turns off meter after 10 minutes of non-use to conserve batteries.
Dual Range - Measures from 0 - 999 ppm, with a resolution of 1ppm. From 1000 to 9990 ppm, the resolution is 10 ppm, indicated by a blinking 'x10' image.
Factory Calibrated: our meters are calibrated with a 342 ppm NaCl solution. Meters can be recalibrated with a mini-screwdriver.
Recommended for fresh water aquariums, aquaculture and ponds.
