The GNV-720 and GNV-725 humidity temperature meters from Global Specialties, Yorba Linda, CA, are portable, dual-function meters with three environmental sensors: one for humidity and two for temperature. Capacitance and semiconductor sensors are incorporated directly into the remote wand. The thermocouple sensor is attached and all three measurements are displayed simultaneously on the LCD screen. Both meters can be connected to a PC to view real-time data populating graphs and tables on the TestLink software. Features include min/max and auto-off functionality, and relative measurement functionality. The GNV-725 with data-logging can record up to 16,300 data points.
