Quantum Sensor

Available on backorder

Features:

  • Uniform sensitivity across the PAR waveband for accurate measurements outdoors, under vegetation, or in artificial lighting without changing the calibration
  • Newly designed optical filter tailors the spectral response to an unprecedented performance standard
  • Weather resistant and durable in high-temperature, high-humidity, long-term deployments
  • Cosine correction is accurate even when the light source is not directly overhead
  • Sensor heads are detachable and interchangeable for simplified installation, removal, and recalibration

Specifications:

  • Absolute Calibration: ± 5% traceable to the U.S. National Institute of Standards and Technology (NIST)
  • Sensitivity: Typically 5 μA to 10 μA per 1,000 μmol s-1 m-2
  • Linearity: Maximum deviation of 1% up to 10,000 μmol s-1 m-2
  • Response Time: Less than 1μs (2 m cable terminated into a 604 Ohm load)
  • Temperature Dependence: ± 0.15% per °C maximum
  • Cosine Correction: Cosine corrected up to 82° angle of incidence
  • Azimuth: < ± 1% error over 360° at a 45° elevation
  • Tilt: No error induced from orientation
  • Operating Temperature Range: −40 °C to 65 °C
  • Relative Humidity Range: 0% to 100% RH, Non-Condensing
  • Detector: High stability silicon photovoltaic detector (blue enhanced)
  • Sensor Housing: Weatherproof anodized aluminum body with acrylic diffuser and stainless steel hardware; O-ring seal on the sensor base
  • Size: 2.36 cm diameter × 3.63 cm (0.93” × 1.43”)
  • Weight: 24 g head; 60 g base/cable (2 m) with screws
  • Cable Length: 2 m, 5 m, 15 m, 50 m (6.5’, 16.4’, 49.2’, 164’)
