HydroC / CO2 Generation II

Spec Sheet Applications

In-situ measurement of dissolved CH4 motivated by: Air- sea gas exchange; Ocean Acidification; Limnology; Climate Studies; Agriculture/ Fish Farming; Fresh water control; Carbon Capture and Storage (CCS)

Detector

High-precision optical analysing NDIR system ● Maintenance free

Principle

Dissolved CO2 molecules diffuse through a silicone membrane into the patented detector chamber, where their number is determined by means of IR absorption spectrometry. Concentration dependent IR light intensities are converted into output signals.

Dimension/ Weight

90 d x 376 mm corrosion-free titanium/ 4,7 kg (3 kg in water)

Operation depth

2000, 4000, 6000 m version available

Temperature range

3 … +30°C (Arctic version: -2 … 25°C)

Measuring range

0… 3000 ppm (other ranges available) ● Standard calibration is 200… 1000ppm ● Units selectable: µatm, ppm, etc.

Equilibration time

first signal after 5s, T63 ~ 45 sec (with external pump)

Resolution

< 1 ppm

Accuracy

± 1 % reading (as the total sum of all the errors)

Calibration

Calibration unit is ppm ● Partial pressure in µatm is derived (internal sensors for pressure, temperature and humidity) ● Recalibration recommended every 12 months

Drift correction / Features

Dual channel NDIR unit ● Auto zeroing on programmed intervals or initiated manually with software ● Included zeroing cartridge lasts for approx. 1 year

Connector

Connector SUBCONN® MCBH8-M Titanium 8-pin ● Others on request

Power supply/ Consumption (@12 VDC)

Typ. 12 VDC (11 - 24 VDC) (Arctic version: 12 - 24 VDC) ● warm- up phase 2- 30min (depending on water temp) Appr. 300 mA + max. 150 mA small external pump (option) + max. 550 mA big external pump (option)

Data Interface

RS-232C and RS-485 ● Data format ASCII NMEA-0183

Software

Windows® Software DETECT™ included (real time data visualization, setting of sensor parameters, download data from internal data logger) ● Adaption to user-software ● Sleep mode function user configurable

Options

● Analogue Output: 0 – 5/10 V (Range / Full-scale can be user-configured) ● Internal or external data logger (µSD card/ CF card) ● external Battery Pack (e.g. 200 Ah Lithium (SAFT LSH 20)) ● Build-in water temperature probe for concentration calculation ● ROV and AUV adaption packages ● Profiling and mooring frames ● HydroC™/CO2 (and/or CH4) FT sensor for underway (FerryBox) and lab applications ● biofouling protection ● external mounted pump with flow head for faster response time
