Opis
Bezdotykowy miernik zawartości chlorofilu typu CM1000. Obliczanie względnej zawartości chlorofilu na zasadzie pomiaru światła otoczenia i odbitego dla długości fal 700 nm i 840 nm. Pole widzenia w zakresie 30 do 180 cm. Minimalna odległość pomiędzy miernikiem a badanym obiektem: ok. 30 cm.
Maksymalna odległość pomiędzy miernikiem a badanym obiektem: ok. 180 cm (dla wyspecyfikowanej dokładności).
“Point-and-shoot” technology to instantly measure relative chlorophyll content
- Detects stress earlier than visual monitoring
- Technology based on an exclusive patent license from NASA
- Laser guides outline the edges of the measured sample area
- Calculates and displays a running average for multiple readings
- Connects to any GPS receiver that has a serial output option*
- Equipped with internal data logger and RS-232 port
- Records 3,250 measurements (1,350 with added GPS/DGPS option)
- Configure and download meter with FieldScout® software (not included)**
- Compatible with SpecMaps™ online web-mapping application
- Includes hard carrying case and batteries
* GPS interface requires two cables. The GPS/DGPS cable (item 2950CV5) is available from Spectrum. A PC serial interface cable supplied by the manufacturer of the GPS receiver is also required.
** PC cable connects to a computer USB port.
Pomiar względnej zawartości chlorofilu w zakresie 0 – 999.
Wbudowany rejestrator danych dla 1350 pomiarów z podłączonym odbiornikiem GPS lub 3250 pomiarów bez odbiornika GPS – do aktywacji i obsługi rejestratora danych niezbędny program, który należy zamówić oddzielnie.
Zasilanie: 2 x bateria typu AAA.
Measurement Sample: Plant leaves, turf grass canopy
Measurement System: Reflectance; Ambient and reflected 700 nm and 840 nm light are used to calculate the relative chlorophyll index
Measurement Area: Conical viewing area between 12 and 72 in
Minimum Distance: 12 in (30.5 cm) from lens
Maximum Distance: Accuracy is unknown beyond 72 in from lens
| Distance From Lens: | Sample Area (Diameter): |
| 12 in (30.5 cm) | 0.53 in (1.35 cm) |
| 18 in (45.7 cm) | 1.21 in (3.07 cm) |
| 48 in (1.22 m) | 4.65 in (11.8 cm) |
Receptor: (4) photodiodes; (2) for ambient light and (2) for reflected light from the sample (leaf)
Measurement Units: Index of relative chlorophyll content; 0 to 999
Measurement Interval: 2 seconds per measurement
Repeatability: ±5% of reading
Data Logger: Requires software and PC interface cable; Capacity:1,350 measurements with GPS/DGPS; 3,250 measurements without GPS/DGPS; nonvolatile memory
Battery/Life: 2 AAA batteries (included); approx. 3,000 measurements
