DIVING-PAM-II
The Walz DIVING-PAM is an underwater Fluorometer (DIVING-PAM-II/B or -II/R).
Available in 2 versions, the Walz DIVING-PAM can measure blue light or red light.
- DIVING-PAM-II/B for blue light
- DIVING-PAM-II/R for red light
- DIVING-PAM-II/B: Underwater Fluorometer with Miniature Spectrometer featuring blue measuring light and blue actinic light (470 nm) plus far-red light (740 nm); with enhanced sensitivity due to detection of short wavelength chlorophyll fluorescence; not recommended for cyanobacteria. With waterproof Perspex housing, backlit transflective LCD display (160 x 104 dots) operated by 10 infrared reflection buttons, high resolution depth and temperature sensors, and built-in lead-acid battery. Including Fiberoptics DIVING-F, Miniature Spectrometer MINI-SPEC for measurements of PAR, fluorescence emission and reflection spectra, USB cable 000130606252, Underwater Cable DIVING-II/K5 (5 m) for remote operation of DIVING-PAM-II, Power Supply MINI-PAM-II/N, PC Interface Box DIVING-PAM-II/I with connectors for USB cable, underwater cable and power supply, Distance Clip 60° 2010-A, Dark Leaf Clip DIVING-LC (3 pcs), Surface Holder DIVING-SH, Transport Case DIVING-PAM-II/T and WinControl-3 Software (Windows 7/8/10). Communication: USB and IEEE 802.11 b/g/n wireless LAN. Submersible down to 50 m.
- DIVING-PAM-II/R: Underwater Fluorometer with Miniature Spectrometer with red (655 nm) LED delivering measuring and actinic light as well as saturation pulses, and far red LED (740 nm) for selective PS I excitation. With waterproof Perspex housing, backlit transflective LCD display (160 x 104 dots) operated by 10 infrared reflection buttons, high resolution depth and temperature sensors, and built-in lead-acid battery. Including Fiberoptics DIVING-F, Miniature Spectrometer MINI-SPEC for measurements of PAR, fluorescence emission and reflection spectra, USB cable 000130606252, Underwater Cable DIVING-II/K5 (5 m) for remote operation of DIVING-PAM-II, Power Supply MINI-PAM-II/N, PC Interface Box DIVING-PAM-II/I with connectors for USB cable, underwater cable and power supply, Distance Clip 60° 2010-A, Dark Leaf Clip DIVING-LC (3 pcs), Surface Holder DIVING-SH, Transport Case DIVING-PAM-II/T and WinControl-3 Software (Windows 7/8/10). Communication: USB and IEEE 802.11 b/g/n wireless LAN. Submersible down to 50 m.
