• Versatile; The vacuum gauge replaces multiple HVAC gauges and was developed to deliver extremely precise temperature, pressure, and vacuum measurements on refrigerant systems and heat pumps
• User-friendly; With its intuitive menu, 4-way valve block and automated probe connection, the digital manifold gauge provides convenient pressure measurement in areas that are difficult to access
• Wide range; The micron gauge offers reliable temperature measuring range of -58° to 302 °F / -50 to +150 °C, pressure measuring range of -15 to 870 psi / -1 to 60 bar, and vacuum measuring range of 0 to 20000 micron
• Precise; Thanks to the sensitive sensors, the vacuum gauge provides temperature accuracy of +-0.9 °F / +-0.5 °C, pressure measurement accuracy +-0.5 % of full-scale value, and vacuum measurement accuracy +- (10 micron + 10 % of mv) (100 to 1000 micron)
• Smart App; Take advantage of clearly visualized documentation from a smartphone or tablet. Remotely operate your refrigerant gauge, execute service and maintenance tasks, and send results directly from the job site
