Product Overview

In suspected arson cases, it is part of the fire investigation to prove that there is no other cause of the fire. The Fire Investigation Kit can be used to detect hydrocarbon compounds such as those found in petrol, alkanes, and cycloalkanes. Fire investigators including the police, consultants and private fire investigators acting on behalf of insurance companies, will search for every type of fire accelerant such as grill lighters, lighter fuel, liquid glue and cleaning agents.

Key Features

  • Improved robust design can withstand harsh environments
  • IP65 ingress protection against a range of weather conditions
  • <2 second response time, one of the fastest and most accurate on the market
  • Instantaneous alarms, RED & AMBER with loud 95 dBA sounder
  • Humidity resistant and anti-contamination design ensures optimal performance
