Description
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 logger is known for its high accuracy, reliability and durability. Each recorder is delivered with a calibration certificate.
The Starmon mini is supported by the SeaStar software and a PC Communication cable. 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 uploaded 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.
