- Page 2 D-Series Handheld IR Scanners The D-Series is an entirely different type of instrument than conventional temperature measuring devices. Designed specifically for the highest possible accuracy, it is the only infrared instrument which can be certified as to NIST-tracable accuracy on real surfaces of unknown emissivity, while completely free of contact errors and heat sinking errors of contact devices.
- Page 3 Target T (F) Conventional Infrared D-Series Ambient T (F) Figure 3. D-Series remains accurate even if the ambient temperature varies, while conventional IR devices have considerable inaccuracies.

- Page 4 Air Flow The Infrared Psychrometry method with the D- Series is a direct application of the thermodynamics and mathematics that defines humidity: the D-Series is capable of measuring the true wet-bulb tempera- ture accurately, and with the dry-bulb temperature, the RH can be computed to a very high accuracy via standard psychrometric equations.
- Page 5 IRt/c sensors require no power and connect directly to standard thermocouple devices available worldwide. Over 300 models offered, covering temperature ranges from -50 to 5000F (-45 to 2760C) with up to 0.01C precision. For more information and pricing, please request a free copy of The IRt/c Book catalog from your local distributor, or Exergen.
