Product Benefits: 

  • The MII 6000V sensor is vented and constructed with vacuum compatible materials and designed for a 48 hour bake out at 150°C.
  • Mercury II’s encoder technology achieves the highest resolution and accuracy in its class, with low cyclical error, low jitter, smaller sensors, and lower power consumption.
  • Broadest Alignment Tolerances: With the broadest alignment tolerances in the industry, a full +/-2 degrees, Mercury II is the easiest and the fastest sensor to align and setup. You can align the Mercury II sensor in under 30 seconds.
