Resolution 0.01%
Drift <1% per year typical
CO2 Sensor
Range 0 to 5,000 ppm
Accuracy

±50 ppm ±5% of reading at 25°C (77°F), less than 90% RH non-condensing and 1,013 mbar

Warm-up Time 15 seconds
Calibration Auto or manual to 400 ppm
Non-linearity <1% of FS
Pressure Dependence 0.13% of reading per mm Hg (corrected via user input for elevation/altitude)
Operating Pressure Range 950 to 1,050 mbar (use Altitude Compensation for outside of this range)
Compensated Pressure Range -305 to 5,486 m (-1,000 to 18,000 ft)
Sensing Method Non-dispersive infrared (NDIR) absorption
Response Time
Temperature 12 minutes to 90% in airflow of 1 m/s (2.2 mph)
RH 1 minute to 90% in airflow of 1 m/s (2.2 mph)
CO2 1 minute to 90% in airflow of 1 m/s (2.2 mph)
Logger
Radio Power 1 mW (0 dBm)
Transmission Range Approximately 30.5 m (100 ft) line-of-sight
Wireless Data Standard Bluetooth Smart (Bluetooth Low Energy, Bluetooth 4.0)
Logger Operating Range 0° to 50°C (32° to 122°F); 0 to 95% RH (non-condensing)
Logging Rate 1 second to 18 hours
Logging Modes Fixed interval (normal, statistics) or burst
Memory Modes Wrap when full or stop when full
Start Modes Immediate, push button, date & time, or next interval
Stop Modes When memory full, push button, date & time, or after a set logging period
Time Accuracy ± 1 minute per month at 25°C (77°F)
Power Source 4 AA 1.5 Volt batteries (user replaceable) or USB power source (5 V DC, 2 Watts) 
Battery Life 6 months, typical with logging and sampling intervals of 5 minutes or slower; 6 months or less with logging and sampling intervals faster than 5 minutes while logging CO2. Entering burst logging mode will impact battery life. With app use, battery life can be reduced by remaining connected, excessive readouts, audible alarms, and paging. Visual/audible alarms and other events can have a marginal impact on battery life.
Memory 128 KB (84,650 measurements, maximum)
Download Type USB 2.0 interface or via Bluetooth Smart
Full Memory Download Time 20 seconds via USB; approximately 60 seconds via Bluetooth Smart, may take longer the further the device is from the logger
LCD LCD is visible from 0° to 50°C (32° to 122°F); the LCD may react slowly or go blank in temperatures outside this range
Size 7.62 x 12.95 x 4.78 cm (3.0 x 5.1 x 1.88 inches)

CastAway Doubts about Conductivity, Depth and Temperature Monitoring

The Sontek CastAway-CTD is a castable device that measures conductivity, temperature and depth. The instrument has been used in the field for over a decade by oceanographers, limnologists, divers, fishers and educators. There have been few changes since the first iteration in 2010, showing that the instrument is durable and accurate without requiring new models.   The CastAway is the first conductivity, temperature and depth (CTD) instrument of its kind. While other CTDs are large and cumbersome to deploy, with cages and isolated sensors, the CastAway is a small, lightweight and easy-to-use instrument. Typical CTDs utilize pumps to ensure water flows over the sensors during deployment.

Dimethyl Sulfide: A Key to Marine Sulfur Biogeochemistry

Christopher Spiese is assistant dean at the Getty College of Arts &amp; Sciences, acting director of the school of social sciences and human interaction, and associate professor of chemistry at Ohio Northern University. He is also a marine sulfur enthusiast. Marine sulfur biogeochemistry, which involves the cycling of sulfur through aquatic biological and geological systems, is essential for the functioning of marine life. However, the exact chemistry involved is not entirely known, piquing the interest of researchers like Spiese. “I went into marine sulfur biogeochemistry during my graduate work. I completed a doctoral environmental chemistry program at SUNY College of Environmental Science and Forestry (SUNY-ESF) under David Kieber.
