Sunburst Sensors, LLC products

Measures the partial pressure of carbon dioxide pCO 2 in water from 200-600 μatm (ranges above 600 are available by request), Uses a highly precise and stable colorimetric reagent method, Provide researchers with valuable in-situ time series data, Depolyable to depths up to 600 meters, Can be deployed in the ocean or in freshwater, Long-term depolyments - can run for more than a year taking hourly measurements, Can support up to 3 external instruments such as PAR, dissolved oxygen, chlorophyll fluorometer, or CTD, Can support inductive modems or external loggers if required. , Biofouling Package available for deployments in productive environments.

Measures pHT (total hydrogen scale) in the marine pH range of 7-9, Uses a highly accurate colorimetric reagent method, System does not suffer from the drift that plagues most electrode based pH probes, Designed to provide researchers with valuable in-situ time series data at depths up to 600 meters, 234-day deployment capability (hourly measurements, 25C), Extra battery package allows the SAMI-pH to run for more than a year, Can support up to 3 external instruments (e.g., PAR, dissolved oxygen, chlorophyll fluorometer, CTD), Supports Seabird underwater inductive modems or external loggers via RS-232

The iSAMI-pH is based on the same technology as the larger, more expensive SAMI-pH, but is meant for use at the surface, for use on buoys, drifters, etc. Measures pHT (total hydrogen scale) in the marine pH range of 7-9, Uses a highly accurate colorimetric reagent method, System does not suffer from the drift that plagues most electrode based pH probes, Designed to provide researchers with valuable in-situ time series data near the surface - depths to 3 m., 160-day deployment capability (hourly measurements, 25C), External battery package available, or power from buoy, drifter.

The πSAMI-pH is based on the same technology as the larger, more expensive SAMI-pH, but is designed for use to 100 m.Measures pHT (total hydrogen scale) in the marine pH range of 7-9, Uses a highly accurate colorimetric reagent method, System does not suffer from the drift that plagues most electrode based pH probes, Designed to provide researchers with valuable in-situ time series data near the surface - depths to 100 m. 160-day deployment capability (hourly measurements, 25C), Internal battery or power from buoy, drifter.

The Autonomous Flow Through Instrument CO2  (AFT-CO2) has the following characteristics: Measures the partial pressure of CO2in water (pCO2- wet) from 150-700 μatm (other ranges available by request), Based on the same technology as the SAMI-CO2, Packaged to be plumbed into a sample line on a research vessel, Once programmed and launched, the AFT-CO2 can run autonomously or while connected to a PC if real-time data is required, Logs own data, Can be configured to support other external instruments if required, Uses a highly accurate colorimetric reagent method, Calibrated against a NIST-traceable NDIR system, Accurate +/- 3 μatm, >Designed to provide researchers with valuable data during research cruises with minimal oversight.
