The SRS2 Wireless Refrigerant Scale allows HVAC technicians to make a quick assessment of cooling systems without wires. The wireless remote features a backlit display and a flip-up magnetic clip that allows the technicans to hang the remote at eye level during use. The platform has a solid aluminum design, with rubber bumpers to prevent damage. The unit has a 33-ft range, and the remote is able to store the last zero point when entering standby or shut-off mode, so that it is not necessary to constantly recalibrate.
