Underwater Temperature Recorder

Starmon mini is a temperature recorder designed for use in oceans, rivers, and lakes.  Starmon mini records the temperature and stores the data into an internal memory under the control of a microprocessor. 

The recorder is supplied with an application Windows software and a PC communication cable, which are the necessary accessories to operate and communicate with the recorder.  When Starmon mini is connected to a PC computer, the software can be used to set up the sampling interval and start time of the recordings.   After the recorder has been recovered from the deployment site, the data can be retrieved by connecting the Starmon mini to a PC computer and use the software to upload data from the recorder.

Memory: 350,000 measurements
Battery life: 5 years (replaceble)
Accuracy: +/-0.2°C (0.36°F)

Starmon hi-temp is a temperature recorder designed for use in high temperature ranges.  Starmon hi-temp records the temperature and stores the data into an internal memory under the control of a microprocessor. 

The Starmon hi-temp was designed for power companies who wanted to record temperature in water pipelines.  One usage is for example recording of temperature in pipelines in people's houses.  The Starmon hi-temp has an external thread and can be screwed upon the pipeline, and the temperature probe is sticks into the water-flow in the pipeline.  The recorder is left there for collecting temperature data.

Sensors: Temperature (optionally available sensors: pressure/depth, pitch & roll, salinity) 
Memory size: 174,000 measurements (option for increasing to 262,000 measurements) 
Battery life: Up to 5 years
Depth: Down to 3500m   

The DST centi-T temperature logger has long battery life, weighs only 12g in water (19g in air).
Its dimensions are 15 mm diameter x 46 mm length.  

DST centi-T is ideal as a stand alone logger for sampling in the ocean, fresh water or other situations where
there is need for collecting temperature over a period of time.

See more technical specifications for the submersible temperature monitor.

Sensors: Temperature (pressure/depth optionally available)
Memory size: 43,000 measurements
Battery life: Up to 3 years
Accuracy: +/-0.1°C (0.18°F)

DST milli-T is ideal as a stand-alone logger for temperature recordings in oceans or fresh water or as for other liquid temperature measurements.  It can for example be fastened to underwater gear or equipment, collecting valuable data. 

The DST milli-T is specially designed as a small archival tag for tagging fish for analysing fish migration and distribution. Temperature measurements from the tag can be compared Sea Surface Temperature (SST) obtained from NOAA, for approximation of geolocation. 

The logger weighs only 5g in water and 9,2g in air, and size is 12,5mm x 38.4mm. Its memory stores up to 43,000 measurments per sensor.

Smallest temperature logger in the world!

Sensors: Temperature (pressure/depth optionally available)
Memory size:  43,000 measurements pr. sensor 
Battery life: >12 months
Accuracy: +/-0.2°C  

This is the world's smallest temperature logger, and stores 43,000 measurements in its internal memory. The temperature range is -1°C to 40°C (30°F to 104°F) but outside calibration is available upon request. The sampling interval can be defined in second(s), minute(s) or hour(s).  This small temperature recorder opens up various possibilities for usage, for example tagging of small animals, in sea or at land, and for putting in small containers or vials.
