Surface Water Detection Sensors
Protect Critical Assets from Costly Water Damage
Uncontrolled water leaks and pooling can cause catastrophic damage in controlled environments, compromising product quality, damaging equipment, and interrupting operations. Rees Scientific offers surface water detection solutions that identify leaks and intrusions early, giving you time to act before damage occurs. Whether protecting temperature-controlled storage, laboratory infrastructure, or cleanroom floors, our water detection technology provides real-time alerts and system-wide visibility to keep your environment dry and compliant.
 
      
   
      
  Why Surface Water Monitoring Is Essential
Water may not be as tightly regulated as temperature or pressure, but it poses just as much, if not more, risk when it goes unnoticed. Water leaks can result from:
- HVAC or refrigeration malfunctions
- Condensation buildup
- Pipe ruptures or roof leaks
- Equipment failures (e.g., chillers, washers, cryo tanks)
- User error (e.g., door left open on cold storage)
The consequences of undetected water include:
- Damage to temperature-sensitive products or reagents
- Short circuiting or corrosion of equipment and sensor infrastructure
- Dangerous mold or microbial growth
- Downtime during decontamination or remediation
- Failed inspections, lost accreditation, or noncompliance with best practices
Water monitoring is often the last line of defense, catching what your HVAC and refrigeration systems may have missed.
Rees Scientific’s Surface Water Detection Capabilities
Our system utilizes surface water detection sensors designed for continuous, unattended monitoring of flat surfaces, beneath equipment, and around vulnerable utilities.
Surface Water Sensors

- Detect pooling or dripping water
- Detect multiple zones with a single sensor
- Deployable under laboratory equipment, freezers, refrigerators, cryo tanks, incubators, and HVAC units
- Expandable to support multiple detection zones with one panel
Probes and Cabling

- Low-profile probes sit directly on the floor or within containment pans
- Optional probe extensions allow custom layouts across sensitive areas
- Multiple probe inputs per panel
- Can be routed around corners, across aisles, or through raised floors
Integrated Alarm and Alerting
- Immediate system alerts upon water detection
- Integrates with Rees Monitoring System for centralized logging
- Customizable alarm thresholds and escalation workflows
- 24/7 alerting via email, text, or phone

  Proactive Risk Management for Compliance and Continuity
Water detection supports facility safety and compliance even though it’s not always codified in regulations. That said, it is frequently referenced in:
- CAP accreditation guidelines (especially for blood banks and labs)
- The Joint Commission expectations around environmental risk control
- USP <1079> and <800> in regard to protecting drug integrity and facility infrastructure
- General GxP and QMS standards for environmental risk mitigation
Having auditable logs, alert trails, and a mitigation plan tied to your EMS shows inspectors and leadership that you are committed to facility-wide protection.
 
      
  Seamless Integration with Your Monitoring Ecosystem
Rees Scientific’s surface water detection systems are fully integrated with your broader environmental monitoring system, providing a unified platform for environmental data and emergency response. Water detection points can be managed through:
- Real-time dashboards
- Zone-based alert mapping
- Historical logs and event timelines
- Response documentation for audits or insurance claims
Installation is simple, with both wired and wireless-compatible configurations, depending on your building layout and alerting needs.
