Hydrosurvey - Model CTD48M -Multiparameter Probes
The CTD48 is a small and handy micro processor controlled multiparameter probe for accurate measurements of pressure, temperature and conductivityThe probe is especially designed for limnological measurements on lakes rivers and estuarys but can be used also in shallow water and in the oceanographic range up to 2000 m depth. The probe is equipped with a 4 channel 16 bit data acquisition system of high long-term stability which meets the high precision requirements necessary for oceanographic measurements.
Due to its low weigth the CTD48 is well suited for portable applications without winches. In this case the probe has to be supplied by battery and data is transmitted via RS 232 port to PC, laptop or portable field unit. A 4,3mm multiconductor cable is the connection between PC and probe and can be used up to several hundred meters distance. The CTD48 is well suited for borehole applications. The small diameter allows measurements in boreholes from 2” to 4” size.The probe and sensors are made of corrosion free materials. Housing and sensor protection tube have a rugged design.
