Lutron YK-2001PHA

YK-2001PHA – Multi-Function Meter for pH, ORP, DO, Conductivity / TDS, and Salt Percentage

The YK-2001PHA is a versatile instrument combining multiple measurements in one device: pH / ORP, dissolved oxygen (DO), conductivity / total dissolved solids (CD/TDS), and salt content. Equipped with automatic temperature compensation (ATC), various probe options, and data output via RS232/USB. Suitable for water quality control, laboratories, aquaculture, food processing, environmental monitoring, and industrial use.

Main Features:

• Measures pH (0.00–14.00) and ORP (±1999 mV)
• Conductivity / TDS / Salt: wide ranges from µS to mS, and salt % by weight
• Dissolved Oxygen (DO) measurement with polarographic probe
• Automatic Temperature Compensation (0–60 °C), or manual mode
• Large backlit LCD display for clear readability
• Data hold, records Max / Min values
• Probe flexibility: interchangeable probes for different functions (pH, ORP, DO, etc.)
• RS232 / USB PC interface
• Auto-power off or manual power control
