With its light weight and small size, the user can carry the RX-QC at all times. Should it be dropped, even if not in its leather carrying case, it will not be damaged or become inoperative 99 times out of 100.
Because the gauge is so durable, the RX-QC comes with a lifetime guarantee. The key to the gauge's durability is its sliding vernier scale- there are no cams, gears, or levers to wear out. This vernier scale holds the maximum reading, and is especially useful for testing in hard to reach areas. The vernier scale is marked in increments of 5 points, and with a little practice, one can obtain readings to within 1 point.
All RX-QC models are supplied with a NIST traceable calibration certificate.
