Compact and durable
The robust temperature and depth data logger, Starmon TD, is designed to withstand harsh conditions and long-term deployment subsea. The logger is durable with its robust and non-corrosive housing. Recorded data is stored in the logger‘s internal memory with a time stamp for each measurement. A calibration certificate is delivered with each instrument.
For flexible mounting, Starmon TD has an attachment hole and two slots for strapping to moorings, nets or deployment lines.
Fast and accurate
The temperature sensor has a fast response of 2 seconds and the depth sensor has immediate response. Depth accuracy is +/-0.3% of full range and temperature accuracy is +/-0.025°C. Sampling intervals are user programmable and can be set down to 15 times per second.
Long life and large memory
The replaceable battery typically has a long life of over 10 years. Actual lifetime depends on sampling interval used and frequency of use. Memory size is 8.4 million recordings per sensor.
Flexibility in sampling
Fastest possible sampling interval is 20 times per second. Up to seven different intervals can be set for the same measurement sequence. This is especially useful when more frequent measurements are needed at a certain time period.
Simple in use
By unscrewing the end cap of the housing, a cable plug becomes accessible. A standard USB cable connects directly from logger to a PC computer. In the application software, SeaStar, the user sets the start time, start date and sampling interval before starting the logger.
Easy viewing of data
After the logger has been recovered, Starmon TD is connected to a PC and the recorded data downloaded. Results are displayed in the SeaStar software as a graph and table. Dataset can be exported to other data processing software.
A set of USB cable and SeaStar software needs to be purchased with the first order.
