Starmon mini is an underwater temperature recorder designed to withstand harsh environments. Starmon mini measures and records temperature and stores the data into its internal memory with a real-time clock reference for each measurement. Starmon mini submersible temperature recorder is known for its high accuracy, reliability and durability. Each recorder is delivered with a calibration certificate.
By unscrewing the end cap of the housing a cable plug becomes accessible. The Communication Cable connects directly from recorder to a PC computer. In addition to the cable the SeaStar software is used. In SeaStar the user sets the start time, start date and sampling interval before starting the recorder. After the recorder has been recovered, Starmon mini is connected to a PC and the recorded data is downloaded into the SeaStar software. Results are displayed both in graphic and tabular form.
A set of PC communication cable and SeaStar software needs to be purchased with the first order. Starmon mini has a non-corrosive and robust plastic housing. For more extreme pressures/depths or higher temperatures, the Starmon mini is available in titanium housing. A stainless steel protective housing for extra protection is also available.
