DO 9721 - Delta OHM Optical Power Meters

Get Quote

  • Model: DO 9721
  • Manufactured by: Delta OHM
  • Type: Irradiance
  • High end wavelength limit: 950 nm
  • Measurement Units: Watt/cm2
  • Extra Specifications: Quantum Photo-Radiometer

The DO 9721 quantum photo-radiometer and thermometer data logger has been designed for measuring illuminance, irradiance, luminance, and temperature.
The instrument has two inputs, A and B, and automatically recognises the probes connected, whether they are illuminance, irradiance, luminance, or temperature probes, and can display the difference between the two inputs.
As the probes are interchangeable, it is possible to choose the most suitable combination for all applications without having to recalibrate the instrument.

The Data Logger function lets the instrument store up to 30,000 readings. The sampling period varies from 1 second to 12 hours. The data acquired may later be transferred to a PC or printer by means of the opto-insulated serial line. For each value stored the date and time of acquisition are indicated. Each acquisition block end with a report that provides the maximum, minimum, and mean values.
Other functions such as Hold, Rel, Record, and Q further enrich performance.

With its versatility and its storage capacity, the instrument suits a wide variety of applications, both in the field and in the laboratory.
