CEM DT-9883M 8 in 1 particle counter, Gas detectors (TVOC , HCHO, CO2), Temperature & humidity

CEM DT-9883M  8 in 1 Handheld particle counter 

— for HVAC, indoor Air quality, industrial

 

These particles refer to fine dust, or smoke scattered in the air. Its main sources include vehicle exhaust, power plants, garbage incinerators, etc. Particles with a relative diameter of less than or equal to 2.5µm are called PM2.5. These particles are smaller than human cells and are not expelled by the body; instead, they enter directly into the lungs and bloodstream, causing significant harm to the human body

a device designed to track the particles & air quality around us. helping us “see” the invisible air and understand the types and concentrations of pollutants within it, thereby better protecting our health.

With advanced gas detection,  it can protect you and your workplace.

This internal technology and gas sensor are commonly utilized in homes, laboratories, factories, mines, and oil & gas operations to protect people from toxic exposure , and and comply with safety regulations

On top of that,  for measurement data analysis and report.  it can capture videos and photos that are stored into internal memory or a micros card. Use the included software to generate reports with videos, photos and data collections.

Major pollutants and dangerous gases to be detected

--  dust , pollen, smoke, microorganisms
--  PM2.5 and PM10
--  TVOC, HCHO,  CO2   (CO detection only in DT-9881)
--  air temperature , relative humidity

Applications:

Particle counters are widely used in cleanrooms, HVAC inspection, indoor air quality testing, industrial hygiene, and environmental monitoring

-- cleanroom manufacturing  ISO 14644
-- Optics, Aerospace, MEMS
-- Food and Beverage, dairy packaging,
-- Hospital and Pharmacies
-- Laboratory environment
-- Warehouse moisture and mildew prevention testing
-- Indoor air quality test
-- Indoor home Formaldehyde (HCHO) Gas Detector
    e.g.  toxic gas emitted from new renovated room

Air Cleanliness Classification Standard: ISO 14644-1 (International Standard)

ISO 14644 classifies the cleanliness levels of cleanrooms (zones) and related controlled environments based solely on the concentration of airborne particles. It specifically considers particle populations with a cumulative distribution within the size range (lower limit) of 0.1 μm to 5.0 μm.

Based on particle diameter, particles are classified as:

  • Routine particles: 0.1 μm to 5.0 μm
  • Ultrafine particles: < 0.1 μm
  • Macroparticles: > 5.0 μm

The table below lists the maximum concentration limits (number of particles per cubic meter of air) for particles equal to or larger than the specified size.

  • Purpose: Primarily used for indoor air quality testing.
  • Health Risk: Formaldehyde is identified by the World Health Organization (WHO) as a carcinogenic and teratogenic substance.
  • Standard: National standards dictate that indoor formaldehyde content should not exceed 1 ppm (parts per million).
  • Common Sources: Found in paints, adhesives, blending agents, daily chemical products, and potentially in preserved or off-season fruits and vegetables.
  • Prevention: This product uses advanced sensors for real-time detection to prevent harm to the human body.
  • Definition: A general term for organic gaseous volatile substances.
  • Symptoms: Exposure can cause irritation and toxicity, leading to immune system disorders, central nervous system issues (dizziness, headache, lethargy, fatigue, chest tightness), and digestive issues (loss of appetite, nausea).
  • Severe Impact: Can damage the liver and hematopoietic (blood-forming) system and cause allergic reactions.
  • Concentration Levels:
    • 16 mg/m³ – 0.3 mg/m³: Generally harmless to human health.
    • Over 0.5 mg/m³: Indoor TVOC concentration should generally not exceed this limit, which is often surpassed during improper renovations.
  • Description: A colorless, odorless gas at room temperature.
  • Impact: High concentrations affect breathing and can lead to suffocation in severe cases.
