The Palmer model PTG200 digital pressure gauge from Palmer Wahl Instrumentation Group is an excellent substitute for mechanical precision pointer pressure gauges. Powered by three standard AA user-replaceable alkaline batteries, this large backlit LCD screen features five-digit resolution and allows the user to select from nine pressure units. Choices of gauge, sealed gauge, or absolute, compound, and differential models are available. Gauge ranges measure over 2500 bar, compound ranges from -1 to +2.5 bar, and differential ranges from 0.0025 to 0.05 bar. The pressure gauge features fully temperature compensated accuracy from 32°F to 122°F (0°C to 50°C), and is available in accuracies of 0.1% or 0.2% of full scale. More accurate than gauges with analog pointers, the PTG200 is suited for two-point field calibration of process gauges and auto peak recording.
