Product Description

 Photosynthesis Active Radiation Meter

 Photosynthesis active radiation, often abbreviated PAR, designates the spectral range (wave band) of solar radiation from 400 to 700 nanometers that photosynthetic organisms are able to use in the process of photosynthesis. This spectral region corresponds more or less with the range of light visible to the human eye. Photons at shorter wavelengths tend to be so energetic that they can be damaging to cells and tissues, but are mostly filtered out by the ozone layer in the stratosphere.

Product Features :

  • Microprocessor Based
  • Accurate
  • Portable
  • Large LCD Display
  • Membrane Touch Screen Keys
  • Data Logging
  • Computer Interface
  • Dual Power AC/DC


Function Overview
1. The sampling interval can be automatic or manually programmed by the user.

2. The system have online real time display feature, the data and real time parametric curve can be displayed   simultaneously to the host computer as well as the equipment screen
3. The system can work in three different modes

Manual mode: In this mode the user needs to select the time interval  of data storage. There is manual start  and stop function to be used in a field for varied on the spot applications. The data is stored with respect to the real time and then the same can be transferred to the computer in the laboratory.

Automatic mode: the first time interval is set up, apparatus in accordance with predetermined time interval automatically record data. After data collection, data can be sent to the computer, the software will automatically generate the curve of graphics can be printed and data processing.

Computer lock mode: all the keys on the host computer failure (lock button), in accordance with the computer set time interval automatic sampling, to ensure data authenticity and continuity of the system. In this mode the system will be locked and the setting cannot be altered during the set programmed time interval.

4. AC-DC dual-use, you can get the field data collection at any time measurements can also be placed on record a long time location.

5. Power data retention capabitiy, can retain upto 30000 entries till you transfer the data to the computer system.

6. The equipment is provided with an elaborate computer software capable of detailed data processing and analysis.  The software can be utilized for data collection. Data processing, capabilities, data collection, the data representation could be in the form of curves, spread sheet, bar chart and pie chart.
7. This equipment is equipped with 32-channel simultaneous detection function, which can achieve simultaneous multi-point inspection (a host of parameters can be measured at the same time to install the 32 indicators, multi-channel interface, and sensors need to be provided externally.
