Specifications for WATER-PAM FIBER Version

Emitter-Detector Unit WATER-ED (red)

Design: Metal housing with LED array, photomultiplier, pulse signal preamplifier and cables connecting to photomultiplier (PM) and AUX output sockets of PAM‑CONTROL unit. Featuring measuring chamber with 15 mm diameter quartz cuvette

LED Array: Pulse modulated measuring light, three LEDs peaking at 650 nm. Actinic light/saturation pulses, 12 LEDs peaking at 660 nm. Far-red light, three LEDs peaking at 740 nm. Alternative to far-red light, blue LEDs (460 nm) can be built in for preferential PS I excitation in cyanobacteria. Actinic intensity up to 2000 µmol quanta m‑2 s‑1 of photosynthetically active radiation (PAR). Saturation pulse intensity up to 4000 µmol quanta m‑2 s‑1

Signal detection: Photomultiplier detector based on Photosensor Module H‑6779‑01 (Hamamatsu) with high red sensitivity; featuring pulse preamplifier and automatic overload switch-off; fluorescence detection at wavelengths > 710 nm

Dimensions: 11 cm x 9 cm x 8 cm (L x W x H)

Weight: 600 g (incl. cable 0.6 m long)

Emitter-Detector Unit WATER-ED/B (blue)

Identical to Emitter-Detector Unit WATER-ED except:

LED Array: Pulse modulated measuring light, three LEDs peaking at 460 nm. Actinic light/saturation pulses, 10 LEDs peaking at 460 nm. Far-red light, three LEDs peaking at 740 nm


Stirring Device WATER-S

Design: Miniature stirring motor in plastic housing with adapter for mounting on top of the cuvette in the emitter-detector unit. Equipped with 10 disposable flattened Perspex rods. Self-contained unit powered by a long-life 3 V Lithium Battery. With potentiometer for adjustment of stirring rate

Dimensions: 8 cm x 5 cm x 3 cm (L x W x H)

Weight: 95 g (including battery)

Spherical Micro Quantum Sensor US-SQS/WB

Application: Suspension cuvette

Connects to: WATER-PAM, DUAL-PAM-100, ULM-500 (AUX), PAM-2500 and MINI-PAM (instead of Leaf Clip Holder 2030-B or 2060 M)

Connector: Same as Leaf Clip Holder 2030-B. Includes hood for suspension cuvette, amplifier for AUX input of PAM-CONTROL

Signal output: Two amplification ranges (0…2.5 V DC / 0…1000 μmol m-2 s-1 or 0…2.5 V DC / 0…20.000 μmol m-2 s-1). Power provided by instrument to which the sensor is connected

Cable length: 3 m + 0.5 m

Size: Sensor, diameter 1 cm, length 11 cm. Hood, diameter 3.4 cm, height 3.2 cm. Amplifier, 5 x 5 x 5 cm (W x L x H)

Weight: 175 g
