Singapore Air Quality Testing

Indoor Environmental Diagnostics Service

What you can’t see can harm you! Indoor levels of air pollutants can be 2-5 times higher, and occasionally 100 times higher, than outdoor levels. Big Red’s expertise is in identifying and eliminating environment – related reactions or allergies. If you are currently suffering from environment-related symptoms, and seek to find the root cause–you have come to the right place!

We offer the following “IEQ” testing services:

---

Specific Indoor Air Contaminants:

Carbon Dioxide, ppm

Carbon dioxide concentration is monitored using an Indoor Air Quality Gas Monitor.

Carbon Monoxide (CO), ppm

Carbon monoxide concentration is determined using a Toxic Gas Monitor with CO Sensor.

Formaldehyde (HCHO), ppm

Formaldehyde concentration is analyzed using a Photo Acoustic Sensor.

Ozone (O₃), ppm

Ozone concentration in air is measured using a Toxic Gas Monitor with ozone sensor.

---

Specific Physical Parameters:

Relative Humidity and Temperature

Relative humidity and air temperature are measured using an Indoor Air Quality Monitor.

Air Movement and Air Flow

Air velocity and air flow are measured using an anemometer.

Specific Classes Of Contaminants:

Respirable Suspended Particulates (RSP), no./m³

Respirable Suspended Particulates are measured using a Portable Dust Monitor from 0.75pm to 10pm.

Volatile Organic Compounds (TVOC), ppm

Total Volatile Organic Compound is determined by means of a Portable Photo Ionization Detection System.

Total Bacteria And Fungal Counts, cfu/m³

Indoor air is sampled using an Andersen Single Stage Air Sampler at a sampling volume of 160 litres.

Bacteria & Mold Speciation

Big Red offers bacteria and mold speciation services in Singapore. The test can be done thru air or swab sampling.

Fungal Culture

Big Red is one of the only lab in Singapore able to analyze viable spores from Air, Bulk, Dust, Swab and Rodac contact plates locally in house.

Our objective approach, based on the collection and utilisation of scientific evidence, has helped us identify the root causes of a myriad of environmental problems – and has provided effective solutions for our satisfied customers. This has earned us a reputation for delivering Solutions for Healthier Environments.
