The Myron L 512T3 DS TDS Meter is a compact, portable instrument designed to measure Total Dissolved Solids (TDS) in water and other solutions. The meter operates using the principle of electrical conductivity and converts the conductivity measurement directly into parts per million (PPM) of Total Dissolved Solids. The 512T3 has a 0–500 PPM range.

Specifications:

• TDS 0-500 parts per million (PPM)
• Single range
• Readout 2½ in. taut-band shock resistant meter
• Accuracy: Conductivity ±2% full scale
• Repeatability ±1%
• Temperature Automatic (to 25°C/77ºF) for conductivity Compensation samples between 10-71°C/50-160°F
• Circuitry Very stable; requires minimal recalibration
• Cell Cup Chip and crack resistant polyethylene
• Power One 9 volt battery supplied; Battery Life: >2000 tests/1 year
• Electrodes (built-in) Conductivity: Never need replatinizing
