Vacuum Gauge with Digital Readout

An electronic vacuum gauge replaces hazardous mercury manometers. Readout does not require interpolation. Large direct-read 4 digit display (Digits are 0.4 in high; display area is 1.89x0.71 in) shows vacuum to one decimal place. Vacuum source attaches to built-in barb fitting. The portable gauge can be powered by battery or 110 V converter (included). When battery power is selected, auto-sleep mode shuts down instrument after 20 minutes without use. Low battery indicator included. Display range is 0-1000 mm Hg absolute, Resolution is 0.1 mm Hg. Accuracy is ± 0.5% full scale. An optional NIST traceable certificate is available
