A digital pressure gauge, the Palmer Precision Test Gauge is an ideal substitute for precision mechanical pressure gauges and perfect for use in field pressure calibration, said the company. The 3.9-inch-diameter dial displays up to six digits on its easy-to-read, backlit LCD screen and allows the user to select measuring in different pressure units. Featuring fully temperature-compensated accuracy from 32-122°F (0-50°C), the test gauge is available in accuracies of 0.5, 0.1, 0.05, and 0.025 percent of full scale. High-accuracy models are ideally suited for precision laboratory applications, the company said. Standard models are available with atmospheric reference choices of gauge, sealed gauge, or absolute; compound and differential models are also available.
