Safety DETEHIT CWD-3 CBRN Detection Strips

Product Description

MIRA Safety DETEHIT CWD-3 Detection Strips help you identify dangerous concentrations of chemical warfare agents (CWAs) and insecticides in the air, in water, in food, or on hard surfaces. These strips are designed to identify two of the deadliest groups of CWAs—G agents (sarin, soman, tabun) and V agents (VX Gas). These strips are ideal for detecting whether it’s safe to remove CBRN gear after exposure to CWA threats. Professionals worldwide use DETEHIT detection strips for both military and civilian applications.

 Key Features of MIRA Safety DETEHIT CWD-3 Detection Strips:

  • Detects nerve agents in the air in as little as 2–3 minutes
  • 10 individually packaged strips per sealed tube with instructions
  • Compact packaging is pocket-friendly and easy to carry 
  • A single strip can test for airborne CWAs and indicate whether concentrations have reduced enough to safely remove PPE
  • Unlike other CWA detection tools, DETEHIT can test food and drinking water for potability and the presence of CWAs
  • Operating temperature range: -20°C to 40°C (-4°F to 104°F)

Technical Specifications

Like a canary in a coal mine, DETEHIT detection strips are designed to provide you with a clear early warning whether your environment is safe or not.

Each plastic testing strip contains a white cotton cloth reaction zone with immobilized cholinesterase, a paper zone with chromogen substrate, and yellow cotton cloth as the color standard. 

Once you remove the strip from its protective foil, it immediately begins to react with the air to indicate whether CWAs are present.

These strips are ideal for checking PPE post-decontamination, to ensure that your suit is completely free of CWA threats that may be lethal if you remove your gear.

While these strips won’t distinguish between different types of deadly CWAs, they can give you insight into concentration of CWA threats.

If the strip reacts within the first 2–3 minutes, the tested air, water, or food is contaminated. If the strip reacts 5–15 minutes after exposure, concentrations have become low enough that it’s safe to remove your PPE (note: ALWAYS decontaminate before removing PPE like gas masks or hazmat suits).

If the testing strip is exposed to food or drinking water and takes 15–30 minutes to react, it’s safe to eat/drink. This is a unique advantage of DETEHIT strips, making them a highly reliable tool for testing your food and water for CWAs or pesticides.

To simplify the various conditions New & Used items may have, we created a conditions guide:

  • New Condition: new with or without tags, various dates and manufacturers. 

  • Good Condition: shows signs of use, light fading/ possible small stains and or small factory repairs. Tags may be legible, may have name tapes and patches sewn on by previous owner. Various dates and manufacturers.

  • Fair Condition: shows signs of use, fading/ small stains/ factory repairs. Tags may be legible, may have name tapes and patches sewn on by previous owner. Various dates and manufacturers.

  • Poor Condition: shows signs of heavy use, fading/ stains/ holes/ rips/ major factory repairs. Tags may be legible, may have name tapes and patches sewn on by previous owner. Various dates and manufacturers.

Military surplus comes in a variety of different conditions based the three " " rule: What, Where, When.

  • Depending on what the item is will generally determine the amount of use and what it was used for. This is important because some items do not endure the torture of being in the field for prolonged periods of time, while others might.
  1. Ex: Dress Uniforms are not worn in combat, therefore generally, there is lighter use than issued combat/working uniforms.

  • Knowing where the item most likely was issued/stored will generally determine the environment it was exposed to. This is important because some items are exposed to harsher conditions than others, or are straight from storage.
  1. Ex: Uniforms & Gear issued in the Vietnam War saw extreme heat and moister, giving those items specific textures/smells/common problems, while the same items issued to troops in occupied Europe do not have those attributes (Generally better conditions). 
  2. Ex: Uniforms & Gear stored in a controlled environment (warehouses or similar areas) feel and smell different than if it is stored in a non-controlled environment (Random areas/outside/or exposed to elements)

  • Time is a huge factor, when something was issued generally determines the age of the item. As time goes by everything ages, this is the circle of life and it does apply to inanimate objects, like military surplus. Items will show signs of age, typically tarnished metal/fading/stains/rips/holes/rot/smell. The exception to the rule is NOS ( New old stock) items or ones stored carefully in controlled environments.
  1. Ex: Uniforms & Gear from World War 2 are generally made of canvas/leather/twill or HBT fabric, and are close to 100 years old. These items have more than likely seen combat or were reissued in the Korean or Vietnam Wars. Extensive use and the fact that they are almost a century old will reflect the condition & price. This applies to any era. 
  2. Ex: Uniforms & Gear from the original factory box, or items stored carefully in controlled environments will generally retain their durability and "new" look. The age of an item sometimes is not a factor BUT only when it is properly stored or carefully looked after.
