miniBackScat I

 

 

moniBSC1_1
 

The miniBackScat I fluorometers 1010 to 1012 are designed for the in situ measurement of the concentration of Chlorophyll a of green and brown algae and/or blue algae respectively.

Features:
- tuned to Chlorophyll a, excellent selectivity, wide measuring range,
  high sensitivity
- standard analogue output, output linear in concentration
- compact instrument, small outlines, titanium connector,
  maintenance-free for long periods
- very low power consumption, wide voltage range of the power supply,
  fast readiness after power-on
- electronic compensation of daylight interference
- quanta controlled excitation
- two measuring ranges with automatic, manual and remote control
- options: titanium housing, integrated turbidity sensor, depth sensor

moniBSC1_2         - Light Source: 2 GaN-LED, peak wavelength
  450 nm, quanta controlled emission
- Detector: Silicon diodes, detector filter
  tuned to Chlorophyll a fluorescence,
  peak wavelength 683 nm
- Ranges: 0 – 10 μg/l and 0 – 100 μg/l
  selectable by turning the front cap,
  manual, automatic and remote control
- Sensitivities: 0.02 μg/l, 0.1 μg/l
- Signal Output: 0 – 10 V analogue,
  (option: 0 – 5 V),linear in concentration
- Time Constant: 150 ms
- Range Input/Output: 0..+5 V (max. 15 V) in/
  0..+5 V (man. 10 V) out
- Maximum Operating Depth: 500m,
  Optional Titanium Version: 2500m

 miniBackScat II

 

 

moniBSC2_1

 

 

The miniBackScat-II 1021 fluorometer is designed for the in situ measurement of the concentration of Chlorophyll a. It allows for simultaneous measurement of two fluorescent agents: Chlorophyll a of blue and/or green plus brown algae.

Features:

- Chlorophyll a of blue and/or green plus brown algae, wide measuring range,
   high sensitivity, low cross-talk
- Standard analogue output, output linear in concentration
- Compact instrument, small outlines, titanium connector,
  maintenance-free for long periods
- Low power consumption, wide voltage range of the power supply,
  fast readiness after power-on
- No daylight interference
- Quanta controlled excitation
- Two measuring ranges with automatic and remote control
- Options: titanium housing, integrated turbidity sensor, DOM sensor

 

 moniBSC2_2         - Light Sources: 4 LEDs, peak wavelengths
  450nm, 590nm, quanta controlled emission
- Spectra: 3 spectra selectable, remote and
  manual control (turning the front cap)
- Detector: Silicon diodes, detector filter
  tuned to Chlorophyll a fluorescence,
  peak wavelength 683 nm
- Ranges: 0 – 10 μg/l and 0 – 100 μg/l
  automatic and remote control
- Sensitivities: 0.02 μg/l, 0.1 μg/l
- Signal Output: 0 – 10 V analogue,
  option: 0 – 5 V linear in concentration,
  model 1022 provides two separate signal
  outputs,
- Time Constant: 150 ms
- Range Input/Output: 0..+ 5 V (max. 15 V)
  in/ 0..+5 V (man. 10 V) out
- Maximum Operating Depth: 400 m,
  Optional Titanium Version: 2500m
