Why Choose RM4150S or RM4151S?

  • Remotely Operated – Measurements are automatically uploaded to Bullhorn Web which, along with the mobile application, can be used to change a configuration, take a measurement,
    control interruption and initiate instant off readings.
  • Reliable Interruption – Patented influence and interference technology and GPS-synchronized interruption are available at time of purchase or as a field upgrade.
  • Rugged – Bullhorn remote monitors survive the harshest of conditions, with built-in surge protection and for enhanced safety against surge events, a high-energy surge arrester or
    SurgeProtect Kit can be added.
  • Accurate – AC and DC voltage with 1 percent of reading accuracy all the way through the range. For example, a 1 mV measurement will be accurate within ±10 microvolts. Every
    measurement is automatically calibrated and zeroed. Find and fix small problems before they become big ones.
  • Instant Alerts – You’ll never have to worry about an unknown problem with your unit since you can configure text or email notifications that will immediately inform you about high-priority situations like a low battery or unusually high consumption rates.
  • Integrated Compliance Solution – We provide a complete end-to-end system to prove regulatory compliance. Bullhorn’s field measurements are easily imported into PCS™ Compliance software, and integrated into reports.
