It has a variety of features including a wide range of measurement from 10-4 Torr to 1000 Torr, RS-485 communications, two programmable set points, and a selectable analog output. The bright, color OLED display included on every unit makes it easy to read from a distance and allows settings and calibration to be adjusted at the unit without any additional equipment. Options can be set from four capacitive touch controls located on the top of the unit or through RS-485 communications. The extensive selection of fittings, simplicity of use, ease of sensor replacement, and low cost make this unit an excellent choice for a variety of vacuum applications.
