Measuring Head MONI-HEAD/485

General Design

Housing: Water-tight aluminum cylinder (stainless steel on request) with one end featuring a collimating lens for focusing modulated measuring light, actinic light and saturating light pulses on the sample, and collecting fluorescence

Sample Clip: Consisting of 2 aluminum frames (3.5 x 2.5 cm), held together by a special O-ring, and mounted at a distance of 2.5 cm from the MONI-HEAD/485 optical window. Angle between optical axis of the MONI-HEAD/485 and sample clip plane: 120°

Cables: Data/power cable: 10 m standard length (MONI-HEAD/485 to MONI-IB4/USB or MONI-HEAD/485 to MONI-DA)

Dimensions: Cylinder with diameter of 3 cm and length of 28 cm

Power Consumption: Peak loads during saturating pulses: 7 W. During measuring mode: 0.5 W

Operating temperature: -15 to +40 °C

Weight: 250 g (aluminum), 450 g (stainless steel)

 

Internal Light

Modulated fluorescence excitation: Blue power LED (peak wavelength: 455 nm, full width at half maximum is 18 nm). Photosynthetically active radiation (PAR) of measuring light at level of the sample clip range from 0.1 to 1 μmol m-2 s-1 at low modulation frequencies (5 to 25 Hz), and from 1 to 15 μmol m-2 s-1 at high modulation frequencies (100 to 500 Hz)

Actinic light: Same Power LED as for modulated light. At the level of the sample clip, maximum photosynthetically active radiation of actinic light and saturating flashes are 1500 and more than 3500

Sensors

Fluorescence: PIN-photodiode protected by longpass filter (50% transmittance at 645 nm). Selective window amplifier to measure pulseamplitude modulated (PAM) fluorescence

Photosynthetically active radiation (PAR): Integrated quantum sensor (photodiode protected by near-infrared filters) measuring the radiation reflected by a 1.3 x 0.7 cm area of an optically diffuse Teflon sheet, 1 mm thick, mounted at the edge of the leaf clip

Temperature: Integrated-circuit temperature sensor on circuit board


PC Interface Box MONI-IB4/LAN

Housing: Aluminum case with RS-232, USB-B, Ethernet, power supply sockets, and four M12 5-pole sockets for RS-485 communication

Interfacing: The interface box connects a computer with up to four MON-IHEAD/485 (or one MONI-DA). RS-485 serial data communication is used between interface box and MON-IHEAD/485 or MONI-DA. RS232, USB or Ethernet communication is used between interface box and computer

Recommended maximum cable lengths: To computer via USB and RS-232: 2 m. To computer via Ethernet, 100 m. To MONI-HEAD/485 via RS-485: 10 m. To MONI-DA via RS-485, 100 m
