Chempro 100i IMS – Improved Chemical Detector from Environics


Categories: ,

The ChemPro 100i IMS is a handheld detector for field detection and classification of Chemical Warfare Agents (CWAs) and selected Toxic Industrial Chemicals (TICs). It provides industry leading sensitivity and false alarm rejection in the most user friendly and low maintenance package in its class. Instead of conventional chemical warfare the defense and security organizations are facing new threat scenarios. Chemical accidents, terrorism or criminal activities are the actual challenges soldiers and first responders have to prepare for on a daily basis. Today’s operating environment requires new versatile response tactics incorporating innovative detection equipment.


  • Widest range of detectable chemicals
  • Simple maintenance
  • Easy to operate
  • Versatility (CWA/TIC)
  • Minimal false alarm rate
  • Radiological and biological detection with add on modules


  • Locating leaks and faulty containers
  • Monitoring of industrial sites
  • Chemical safety of harbors and railways
  • Customs and border control
  • Monitoring of mass events and high security meetings
  • Law enforcement agencies
  • Battlefield detection and monitoring
  • CBRN reconnaissance and surveillance

The ChemPro 100i uses an array of detection technologies to detect, classify an measure chemicals enabling simultaneous detection of the widest range of chemicals. The ChemPro 100i is a truly orthogonal detector, it’s heart remaining the Environics’ unique open loop ion mobility Spectrometry (IMS) sensor. The performance is improved with additional sensors that provide a wider range of detectable TICs and improve false alarm rejection.

The ChemPro 100i, unlike traditional closed loop IMS, does not have to purify or chemically modify the sample with consumable sieve packs or dopants. This substantially reduces cost of ownership compared to other chemical detectors. Transport, fielding and operation of the ChemPro 100i are simple and easy because it does not require consumables and only needs maintenance every 3,000 hours (tracked by an internal clock). Even after 3,000 hours you can still use the ChemPro 100i if it passes its simple field check. With the ChemPro 100i you will not be left in the middle of an incident with a CWA/TIC detector that does not work.

Some CW/TIC detectors need to be “exercised” or run once/ day/week/month or else they will not work when an emergency comes. The ChemPro 100i can be stored for years and if it was working when you stored it, the ChemPro 100i will work when you really need it.

The ChemPro 100i features an intuitive, graphical user interface with large menu buttons which are easy to use even when wearing protective equipment with heavy gloves. Interchangeable Li-Ion batteries can be quickly swapped out with a 6 AA battery pack without the use of any tools.

The ChemPro 100i capability can be easily expanded to a full CBRN detection system by utilizing unique cost effective external add on modules including:

  • Radiation Detection Module that enables the Chempro 100i to detect traces of gamma and X-ray radiation. The current dose rate, the accumulated dose reading and alarms are indicated on the display of the Chempro 100i
  • Reader Module adds new functionality in the form of handheld biological detection. It is intended for reading Envi Assay System lateral flow immunoassy tests. The Reader Module stores the test data for evaluation after the mission.
  • GPS Module displays coordinate information on the Chempro 100i display screen and includes the coordinates to the alarm memo when chemicals are detected.
  • Earphone Module is designed for covert operations where silence is vital. When connected to the ChemPro 100i, all audible information is heard through the earphone.
  • All add-on modules are plug and play compatible with the ChemPro 100i and operate using power from the ChemPro 100i battery.
