Multiparameter Probe

The CTD48 is a small and handy micro processor controlled multiparameter probe for accurate measurements of pressure, temperature and conductivity. The probe is especially designed for limnological measurements on lakes, rivers and estuaries, but can also be used in ocean waters of up to 6000 m depth. It is equipped with a 4 channel 16 (20) bit data acquisition system of high long-term stability which meets the high precision requirements necessary for oceanographic measurements. The CTD48 is well-suited for borehole applications. The small diameter allows measurements in boreholes from 48 mm (2“) size. The probe can be powered by battery or DC-power supply (9 to 36 Volt) when using RS-232 (RS-485) output or optional by constant current with FSK telemetry output (coaxial connection) for longer distances.

Medium Sized Multiparameter Probe

Sea and Sun Technologies CTD75M offers excellent reliable performance in limnological, oceanographic, and off-shore areas. The probe is offered for two different applicable depths, 500 m and 2000 m. The CTD75M is a high accuracy probe that measures conductivity, temperature, and pressure as a standard configuration. Furthermore it can be easily configured for a wide range of auxiliary sensors. More detailed information on the sensors can be found in the table below. Sea and Sun Technologies CTD75M records selected data at programmable time intervals whereas the data is stored in a non-volatile FLASH memory with a capacity of 128 Mbytes. A standard RS-232 connection is used for programming, data output, and data acquisition. Data is available as RS 232 signal and optional in online mode as digital FSK signal modulated on constant current.
