LEGIONELLA MONITORING DEVICE (125H)

 

Designed specifically to monitor and report on Legionella compliance, the ISL125H measures the water temperature of up to four pipes using external pipe-mounted temperature probes. By continuously monitoring the pipe temperatures, it is possible to show compliance with legionella regulations, reducing site visits and cost.

  • Connection for up to four external temperature probes

  • Two pulse inputs
  • Battery powered
  • Wall bracket mounting options 
  • Temperature alarm threshold hysteresis 

  • Temperature Edge Intelligence (thresholds – warning, alarm) 

  • Configurable transmit interval for each mode (standard, warning and alarm)

105H - 45 Deg

ADDITIONAL INFORMATION

CONFIGURABLE THRESHOLDS

Configurable high/low thresholds allow different transmit intervals when thresholds are crossed providing advanced edge intelligence to the network, and enable alarms to be generated by Realtime-Online™.
 

REAL-TIME MONITORING 

Data from every sensor in your network is reported back through Invisible Systems Big Data architecture either to our Monitoring and Analytics platform Realtime-Online™, or to a partner cloud platform via our API, ensuring that your data is visible, actionable and valuable to your organisation.
 

NB-IOT 

Data NB-IoT is a standards-based narrowband Low Power Wide Area (LPWA) technology developed to to enable a wide range of new IoT devices and services. NB-IoT devices connect directly to the cellular mobile network via a low-cost SIM card. NB-IoT significantly improves the power consumption of user devices, system capacity and spectrum efficiency.
