PSP32 Monitoring Fluorometer System

Product catalog summary

Overview: The PSP32 Monitoring Chlorophyll Fluorometer System by ADC BioScientific Ltd. is an advanced plant stress probe designed for automatic and remote monitoring of large plant populations over extended periods. It measures a comprehensive range of fluorescence parameters using innovative design and technology.

Specifications: The system supports both light and dark-adapted tests, including quenching and quenching relaxation protocols. It features a daylight dark adaption module for measuring fast-reacting xanthophyll cycle, chloroplast migration, state transitions, and photoinhibition. The system can deliver a 10,000µmol m^-2 s^-1 square-topped saturation flash or FM’ correction option.

Capabilities: The system allows automated, remote monitoring in various environments such as fields, greenhouses, or labs, with a solar power option. It can measure large plant populations using up to 32 probes and provides live data access via a WiFi user interface. The system includes a 'daylight dark adaption' probe with an automated shutter for quenching relaxation and uses blue and/or red actinic light for all quenching parameters and protocols.

Parameters Measured: The system measures both light-adapted and dark-adapted parameters, including Y(II), ETR, PAR, T, FMS, F, Fv/FM’, Fv/F0, F0, FM, FV, and F0’. It also measures quenching parameters using standard and relaxation protocols, rapid light curves, and various light sources.

Technical Details: The system uses a saturation pulse blue and red LED with modulated light, actinic light source, and far-red light source. It employs a pulse modulation method with a PIN photodiode and a 700 ~ 750nm bandpass filter. The sampling rate auto-switches from 1 to 10,000 points per second, and the system has a storage capacity of 2Gb over 500,000 data sets.

Output and Interface: Data is output in comma-delineated files compatible with Excel and can be retrieved via various methods including WiFi, mobile phone, SD card, ethernet, USB stick, radio point-to-point, or satellite phone. The user interface features a graphic, B&W, touch screen display with a menu-driven control box that can be locked and pole-mounted.

Power and Operating Conditions: The system operates on external 12V batteries, solar, or mains power options, and functions within a temperature range of -10°C to 50°C.
