MQS-B Mini Quantum Sensor
Version
Cosine Corrected Mini Quantum Sensor
US-MQS/WB
The US-MQS/WB comprises the sensor MQS-B and the amplifier box. Technically the connection for the US-MQS/WB is the same as for the Leaf Clip Holder 2030-B. Possible connections are:
- PAM Control Unit of WATER-PAM (Aux Input) – especially in the Fiberoptics version (WATER-EDF)
- MULTI-COLOR-PAM (Ext. Sensor)
- PAM-2500 (instead of Leaf Clip)
- MINI-PAM (instead of Leaf Clip)
- DUAL-PAM/F (instead of Leaf Clip)
- PHYTO-PAM-II (Compact version only)
(The adapter set MQS-B/A is always included to this set.)

MQS-B Mini Quantum Sensor (US-MQS/WB)
Design
Cosine-response mini quantum sensor for selective measurement of photosynthetically active radiation (PAR, 400 – 700 nm) with Perspex diffuser disk as light entrance and signal amplifier box
Signal detection
High stability silicone photovoltaic detector with filter set providing equal response to photon fluxes across the PAR spectral range. The typical signal output of the detector is 2 μA / (1000 μmol m‑2 s‑1)
Temperature coefficient of photodiode
0.01 %/K
Absolute calibration
± 5 %
Angular dependence
error < 4 % between angles from -80° to +80° from normal axis
Immersion coefficient
Typically 1.32
Cable length
3 m
Size: Height
16 mm; diameter: 14 mm; Diffuser diameter: 5.5 mm
Weight
32 g
Amplifier box
Two amplification ranges (0 to 1000 and 0 to 20,000 μmol m‑2 s‑1, each range corresponding to 0 to 2.5 V DC). To be connected to the Leaf Clip Holder 2030-B port of the PAM-CONTROL unit. Power provided by the PAM-CONTOL unit. Dimensions: 5 cm x 3 cm x 5 (W x H x D). Weight: 200 g.
