Starmon mini is an underwater temperature recorder designed to withstand harsh environments. Temperature measurements are stored into logger's 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 date & time 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 pressure/depth or higher temperatures, the Starmon mini is available in titanium housing. A stainless steel protective housing for extra protection is also available.

Features on Request
A fast response temperature logger version is available, in plastic housing only. The time constant is then decreased from 18 sec. to 2 sec. This feature is useful when measuring while sinking or towing.
Starmon mini, in titanium housing, can be calibrated for higher temperatures, up to 90°C.
Please contact Star-Oddi with your requirements.
