• Dual Salinity Measurement Options
  Displays salinity in both ppt (g/L) and PSU, with high-resolution and wide range for oceanographic or aquaculture applications.

• Automatic and Manual Calibration Options

  • pH: Two-point manual or automatic calibration using pH 7.01 and 10.01

  • Salinity: One-point automatic calibration using 35.00 ppt solution

  • Temperature: Automatic across 5 to 50 °C range

• High/Low Alarm System
  Configurable alarms for pH, EC, and temperature allow early detection of out-of-range values with enable/disable settings.

• Clear Digital Display
  Easy-to-read 128 x 64 pixel LCD with green backlight for quick data visualization in all lighting conditions.

• Water-Resistant Enclosure
  IP65-rated housing protects the instrument from dust and water, suitable for marine, greenhouse, or lab environments.

• Dual Voltage Power Support
  Operates on 230 VAC (this model), includes 12 VDC adapter; compatible with both 115 and 230 VAC inputs.
