HQ Hand held measurement instrument

A hand-held instrument for measuring oxygen, salinity, pH and redox. Available with various sensor cable lengths.

Compensates automatically for pressure and temperature. When measuring oxygen, both % saturation and mg/liter is displayed. Sensors are ordered separately.

Sensor channels

• HQ30d: 1
• HQ40d: 2
