The ZOOM ZH38 is not only the worlds first dual FOV handheld thermal imager available in the commercial market, but also the first handheld product to feature Shutterless Calibration Technology (SCT) to simplify use and reduce power consumption. With the ZOOMs patented dual-field-of-view design, users can seamlessly switch between a wide field-of-view (FOV) for detection and a narrow FOV for target identification. This 2X increase in optical magnification occurs with an intuitive twist of the objective focus ring and maintains 100 percent of the sensors native resolution. Additionally, the ZOOM ZH38 is the first handheld thermal imager available to feature a full-color 1440X1080 HD OLED display, working in tandem with its ultra sensitive 12um 640 x 512 sensor.
