Multiparameter

The Troll 9500 is a sophisticated and robust water quality instrument with interchangeable sensors.

Combination (Conductivity/Temperature/Pressure)

The CTD350 Sensor provides the accuracy/reliability required for a wide range of monitoring applications.

Combination (Conductivity/Temperature/Pressure/pH)

The CTDP300 is designed to simultaneously measure four key water parameters including Conductivity, Temperature Pressure and pH.

Combination (Conductivity/Temperature/Pressure/pH)

The CTDP1200 provides the convenience of measuring Conductivity, Temperature, Depth and pH from one unit. This unit uses the SDI-12 protocol to output all data readings.

Combination (pH/Electrical Conductivity/Temperature/ Dissolved Oxygen

The CS304 measures pH, Conductivity, Temperature and Dissolved Oxygen.

Combination (pH/Electrical Conductivity/Temperature/ Dissolved Oxygen)

The CS4-1200 also measures Conductivity, Dissolved Oxygen, Temperature and pH from one unit and is suitable for river surveys, esturine monitoring, wastewater discharge and groundwater monitoring.
