DA211 Pre-Amplifier Detectors

The DA211 range of data logger compatible detectors comprise of a photodiode detector with filter glasses, diffuser and a transimpedance amplifier for a voltage output. The detector is sealed in a waterproof enclosure and operates from a single rail power supply.

The detectors feature key designs including:

  • Self-cleaning input diffusers
  • Stay dry diffuser with wide drainage slots
  • Cosine response
  • Infinity error correction ring
  • Aluminum body with resistant anodising
  • High stability silicon photodiodes
  • Internal resistor adjustable for annual calibration
  • Internal resistor adjustable for zero offset bias.
