What Can Both Temtop Air Quality Monitors Measure?

Both the Temtop M2000 2nd and LKC-1000S 2nd provide PM2.5 and PM10 measurements.

PM2.5 refers to fine particulate matter with an aerodynamic diameter of 2.5 micrometres or smaller.

PM10 refers to particles with an aerodynamic diameter of 10 micrometres or smaller, including the PM2.5 fraction.

These measurements are normally expressed in micrograms per cubic metre (µg/m³).

PM2.5 monitoring is relevant during haze events, smoke pollution and combustion-related particulate exposure.

PM10 provides additional information about a broader particle size fraction, including particles associated with soil disturbance, traffic and construction activities.

Both instruments can also provide HCHO formaldehyde measurements and general temperature and relative humidity information.

However, neither instrument identifies individual particle composition or replaces professional occupational exposure sampling.

Temtop M2000 2nd - Main Features and Advantages

The Temtop M2000 2nd is a portable multi-parameter air quality monitor that combines particulate measurement with carbon dioxide monitoring.

Its main measurement functions include:

• PM2.5

• PM10

• CO2 using an NDIR sensor

• HCHO formaldehyde

• Temperature

• Relative humidity

Additional features include a TFT colour display, rechargeable battery, audible alarm, historical readings and USB data export in CSV format.

The CO2 measurement function is particularly relevant for occupied offices, meeting rooms, temporary construction site offices and facility management applications.

Elevated indoor CO2 concentrations can help identify ventilation-related concerns, although CO2 is not a direct measurement of haze or every indoor pollutant.

The M2000 2nd is suitable for supplementary indoor air quality screening and short-duration inspections where environmental conditions are appropriate.

Temtop LKC-1000S 2nd - Main Features and Advantages

The Temtop LKC-1000S 2nd is a portable multi-parameter air quality monitor with an emphasis on particulate pollution and indoor chemical screening.

Its main measurement functions include:

• PM2.5

• PM10

• HCHO formaldehyde

• TVOC total volatile organic compounds

• Temperature

• Relative humidity

• Instrument-generated air quality indication

Additional features include a TFT colour display, rechargeable battery and USB data export.

The TVOC measurement function may be useful for general screening in recently renovated offices, buildings with new furniture and occupied areas where volatile organic compounds are a concern.

TVOC readings from a general-purpose monitor do not identify individual chemicals or replace laboratory-based chemical exposure assessment.

The LKC-1000S 2nd does not measure CO2.

Customers should verify the exact model designation before purchasing because the LKC-1000S 2nd and LKC-1000S+ 2nd have separately published product specifications.

Which Temtop Model Is Better for Construction Site Haze Monitoring?

For basic PM2.5 and PM10 haze monitoring, both models provide the principal particulate measurements.

The choice depends on the additional information required.

Choose the Temtop M2000 2nd when the construction company wants to monitor particulate concentrations together with CO2 in occupied site offices or meeting rooms.

Choose the Temtop LKC-1000S 2nd when the main objective is particulate monitoring together with HCHO and TVOC screening, particularly in renovated or furnished indoor spaces.

Neither instrument is designed as a weatherproof permanent outdoor monitoring station.

For heavy construction dust, respirable crystalline silica exposure or formal occupational hygiene assessment, specialised monitoring and sampling equipment may be necessary.

Which Model Is More Suitable for HSE Safety Officers?

HSE Safety Officers often need to investigate environmental conditions across different workplace locations.

The M2000 2nd can be useful when an inspection includes indoor ventilation-related questions because it measures CO2.

The LKC-1000S 2nd can be useful when an inspection includes general volatile organic compound screening.

For routine haze-related particulate observations, both models offer PM2.5 and PM10 readings.

HSE teams should also record the monitoring location, inspection time, work activity and relevant environmental conditions.

Portable air quality readings provide supplementary screening information and should not be represented as certified employee exposure measurements.

Malaysia DOSH 2026 Haze Guidelines - Important Considerations

Malaysia's Department of Occupational Safety and Health (DOSH) lists the Guidelines for the Protection of Employees Against the Effects of Haze at Workplaces, Second Edition 2026.

The guidance addresses workplace risk management and protective measures during haze conditions.

Employers should check official Air Pollutant Index (API) information from Malaysia's Department of Environment and assess the risks associated with specific work activities.

Relevant considerations include outdoor work intensity, worker health, visibility, dust-generating activities and appropriate protective measures.

The official API is calculated using the applicable Malaysian ambient air pollution methodology.

PM2.5 measurements from the M2000 2nd or LKC-1000S 2nd are local particle concentration readings, not official API values.

A portable monitor reading must not be used by itself to determine whether a construction project must stop work.

Employers should consult the complete current DOSH guidance, applicable legal requirements and workplace risk assessments before making operational decisions.

Applications for Factories, Warehouses and Offices

1. Factory Administration Offices

Both models can provide supplementary PM2.5 and PM10 readings during regional haze events.

The M2000 2nd also provides CO2 information for occupied office ventilation investigations.

2. Construction Site Offices

Temporary site offices may experience particulate infiltration from outdoor haze and nearby construction activities.

Both models can help monitor local indoor particulate trends.

3. Warehouses and Logistics Facilities

Loading bays and vehicle movements can influence indoor particulate conditions.

Portable monitoring can provide preliminary environmental information at selected safe locations.

4. Recently Renovated Offices

The LKC-1000S 2nd includes TVOC monitoring, which may be useful for general screening following renovation or installation of new furnishings.

5. Meeting Rooms and Control Rooms

The M2000 2nd provides CO2 measurements that may support investigations of ventilation-related trends in occupied spaces.

6. Air Purifier Performance Observations

Both instruments can be used to compare PM2.5 readings before and after operating an air purifier under similar conditions.

These comparisons are indicative and do not constitute certified filtration efficiency testing.

How to Compare PM2.5 Readings Using Both Instruments

Step 1: Check the instruments' operating instructions and confirm that both devices are in suitable condition.

Step 2: Position the instruments near each other in a representative indoor location without obstructing their air inlets.

Step 3: Allow sufficient stabilisation time according to the manufacturer's instructions.

Step 4: Record PM2.5 and PM10 readings at the same time.

Step 5: Repeat measurements over a reasonable period rather than relying on one instantaneous reading.

Step 6: Record the temperature, humidity, location and nearby activities.

Step 7: Review differences in readings, recognising that optical particle sensors can respond differently to particle composition, humidity and calibration conditions.

Step 8: Use the results to identify trends and determine whether more specialised investigation is necessary.

Agreement between two portable monitors does not establish reference-grade accuracy or regulatory compliance.

USB Data Export for Workplace Monitoring Records

Both the M2000 2nd and LKC-1000S 2nd support USB data export.

The M2000 2nd provides CSV data export through its instrument menu and USB connection.

The LKC-1000S 2nd also provides data export functionality, with operating steps depending on the exact instrument version.

Exported records can support internal environmental screening and trend reviews.

HSE teams may combine the data with separate notes identifying inspection locations, work activities, ventilation status and official API conditions.

These records should not be described as accredited test reports or certified occupational exposure results.
