Detect dangerous hydrocarbon vapors in dry monitoring wells.  When vapors exceed a programmed threshold, Veeder-Root’s Vapor Sensor sends an audible and visual signal to a TLS-350R or TLS-350 console telling you where the problem is, so you can act quickly to prevent serious safety and environmental hazards.

Key features:

  • Only three wires required to connect to a TLS-350R or TLS-350 monitor
  • Detects vapor and liquid with a fuel alarm or a water alarm

Key benefits:

  • Hydrocarbon vapor exceeding the programmed threshold triggers a Fuel Alarm
  • Liquid present in the monitoring wells triggers a Water Alarm
  • Withstands removal and replacement from monitoring well without sensor damage
  • Easy install: only three wires required to connect to a TLS-350R or TLS-350 monitor
