DescriptionSpectronics Spectroline DMHA Series Digital Radiometers | 0-199.9 mW/cm2 (0-199,900 µW/cm2) Irradiance Range, 0.1 mW/cm2 (100 µW/cm2) Resolution, 3 1/2 digit, 7 segment, LED, 0.5 inch (12.7mm) high Display, 3 readings per second nominal.
OverviewThe Spectroline DMXA-Series and DMHA-Series digital radiometers provide readings from 0-19,990 µW/cm2 or 0-199.9 mW/cm2 (0-199,900 µW/cm2), respectively. They feature an easy-to-read LED display. Their overall accuracy is better than ±5%.These radiometers use high-quality interference filters that exhibit accurate and carefully controlled spectral coverage, practically eliminating unwanted meter sensitivity to infrared interference and other undesirable radiations. This allows the readings to be obtained directly instead of by calculation, a time-consuming and error producing procedure required by certain competitive devices. The interference filters also minimize the “solarization” effect upon the response of the meters over time.All Spectroline radiometers are calibrated to NIST standards by pyroelectric methods for maximum accuracy. They are designed with a low electrical impedance, making their linearity vastly superior to that of any other comparably priced radiometers. The sensor heads are provided with a special diffuser-sensor window that ensures accurate Lambertian or Cosine response.The metering electronics of the DMXA-Series and DMHA-Series radiometers feature better than ±5% accuracy, integrated circuitry, and solid-state LED display. Additional features of the electronics are excellent temperature and over-ranging characteristics. The DMXASeries and DMHA-Series radiometers also have built-in autozeroing.
