Why Choose Bullhorn RM4210 and RM4250 Remote Monitors?
We engineered Bullhorn RM4210 and RM4250 Remote Monitoring Units to provide continual AC corrosion threat tracking.
- Fully integrated form factor
- Easy installation and setup
- Highly accurate readings
A long-lasting battery and satellite (RM4210) or cellular (RM4250) connectivity means these remote monitors provide reliable, near-instantaneous communication. The RM4210 and RM4250 offer:
Quick Installation – Install only takes a few minutes. Wire the RMU to the test station, plug in the batteries, and affix the RMU to the top of the test station or pole. Installation is even faster on a TRITON Test Station since they come ready to plug into a Bullhorn RMU.
Easy Configuration & Economical Data Plans – These RMUs have Bluetooth built-in, making it easy to configure them in the field using Bullhorn® Tools. You do not need extra adapters to connect to the device. Alternatively, you can also configure the RMU via Bullhorn Web from the comfort of your office.
Highly Accurate – Measure within one percent of reading accuracy throughout the range, with auto-calibration and auto-zero for every measurement. For example, a one mV measurement will be accurate within ±10 microvolts. Accuracy is especially critical when using a small AC coupon.
Reporting – Quickly identify problem areas and ensure mitigation effectiveness using flexible reports and graphs.
Value – We can bundle RM4210 or RM4250 with the award-winning Triton triple-coupon test station, so that you can order your AC monitoring equipment in one purchase.
