Dwyer DPG-107 is a digital pressure gauge with a temperature range of 0 to 130°F (-18 to 55°C). It offers high accuracy, with the DPG-000 model having a 0.5% FS accuracy and the DPG-100 model having a ±0.25% FS accuracy, including linearity, hysteresis, and repeatability. The gauge operates on 2 AAA alkaline batteries (included) and has an enclosure rating of NEMA 4/4X (IP66). The housing is made of polycarbonate and anodized aluminum, with a polycarbonate overlay and Buna-N O-rings. The gauge is compatible with liquids and combustible gases, and the display features 4 large digits. It has a 1/4" male NPT process connection and offers a pressure limit of 2x the pressure range for models ≤1000 psi. The thermal effect is minimal, ranging from 0.016% to 0.50% per degree Fahrenheit. The dimensions are 3.00" OD x 1.90" deep (max), and the battery life is approximately 2000 hours. The gauge has a built-in auto shut-off function and a low battery indicator.
