Which Model Is Better for Haze?
For haze alone, both models are suitable because they measure:
-
PM2.5
-
PM10
These are the primary particulate measurements required when investigating haze penetration, room conditions or air purifier performance.
Neither model is automatically “more suitable” simply because it displays more parameters. The best choice depends on what else the buyer wants to investigate.
Choose the M2000 2nd if CO₂ is important.
Choose the LKC-1000S+ 2nd if TVOC is important.
What Does PM2.5 Tell You?
PM2.5 refers to fine airborne particles with a diameter of 2.5 micrometres or smaller.
During haze, PM2.5 measurement can help determine:
-
Whether outdoor particles are entering a building
-
Which room has the highest concentration
-
Whether closing windows produces an improvement
-
Whether an air purifier reduces fine particles
-
Whether particle levels increase when doors open
-
How indoor air changes throughout the day
Both Temtop models provide a local measurement at the instrument’s position.
This should not be confused with Malaysia’s official Air Pollutant Index, which represents the broader outdoor air-quality situation.
Why Choose the Temtop M2000 2nd?
The Temtop M2000 2nd is the more suitable option when the user needs to measure both particulate pollution and carbon dioxide.
According to Temtop’s official specifications, it measures:
-
CO₂
-
PM2.5
-
PM10
-
HCHO
-
Particle information
-
Temperature
-
Relative humidity
It also provides audible or visual alerts, recording functions and data export.
Main Benefit: CO₂ Measurement
CO₂ is commonly monitored as an indicator related to occupancy and ventilation.
It can be useful in:
-
Schools
-
Classrooms
-
Offices
-
Meeting rooms
-
Training rooms
-
Clinics
-
Libraries
-
Enclosed workspaces
-
Conference facilities
A room may have relatively low PM2.5 because its windows are closed during haze, but CO₂ may increase when many people occupy the space for an extended period.
The M2000 2nd allows facility managers to observe both issues using one instrument.
M2000 2nd CO₂ Sensor
Temtop states that the M2000 2nd uses a non-dispersive infrared—NDIR—CO₂ sensor.
The official specification lists:
-
CO₂ measurement range: 0–5,000 ppm
-
Resolution: 1 ppm
-
Accuracy: ±50 ppm plus 5% of the reading
This makes CO₂ the defining difference between the M2000 2nd and LKC-1000S+ 2nd.
Why Choose the Temtop LKC-1000S+ 2nd?
The Temtop LKC-1000S+ 2nd is more suitable when the user wants to monitor particulates together with TVOC and formaldehyde.
According to Temtop, it measures:
-
PM2.5
-
PM10
-
Particle information
-
HCHO
-
TVOC
-
Temperature
-
Relative humidity
-
Air-quality indication
It also offers a histogram function and data export.
Main Benefit: TVOC Measurement
TVOC means total volatile organic compounds.
TVOC screening may be relevant in:
-
Recently renovated homes
-
Newly furnished offices
-
Meeting rooms with new furniture
-
Hotel rooms
-
Interior renovation projects
-
Properties using adhesives or coatings
-
Indoor spaces where chemical odours are reported
The LKC-1000S+ 2nd therefore combines haze monitoring with a wider screening of potential indoor chemical pollution.
It does not include CO₂ as a primary measurement.
What Is the Difference Between HCHO and TVOC?
HCHO refers to formaldehyde, while TVOC is a broader indication covering a group of volatile organic compounds.
Possible indoor sources include:
-
Furniture
-
Composite wood
-
Adhesives
-
Paint
-
Flooring
-
Cleaning products
-
Solvents
-
Renovation materials
Both the M2000 2nd and LKC-1000S+ 2nd measure HCHO.
The LKC-1000S+ 2nd additionally measures TVOC, making it more suitable when volatile organic compounds are part of the investigation.
These readings should be treated as screening measurements. A formal compliance or source-identification investigation may require specialised sampling and laboratory analysis.
Which Model Is Better for Schools?
For most school applications, the Temtop M2000 2nd has the stronger overall combination.
Schools may need to investigate:
-
PM2.5 during haze
-
PM10
-
Classroom occupancy
-
Ventilation
-
Temperature
-
Humidity
-
Formaldehyde in renovated rooms
Because the M2000 2nd includes CO₂, it can help schools review how closing windows during haze affects occupied classrooms.
However, local measurements do not replace official haze, health or education instructions.
Which Model Is Better for Offices?
Choose the M2000 2nd when the main concerns are:
-
Haze
-
Meeting-room occupancy
-
Ventilation
-
CO₂ accumulation
-
Temperature and humidity
-
Formaldehyde
Choose the LKC-1000S+ 2nd when the main concerns are:
-
Haze
-
New furniture
-
Renovation emissions
-
HCHO
-
TVOC
-
Indoor chemical odours
For general facility management, M2000 2nd may offer greater value because CO₂ is frequently relevant to occupied offices.
For renovation-related assessments, LKC-1000S+ 2nd may be the more appropriate choice.
Which Model Is Better for Homes?
The answer depends on the home’s main problem.
Choose M2000 2nd When:
-
You want PM2.5 haze monitoring
-
You also want CO₂
-
You are checking bedrooms with closed doors
-
You want to investigate ventilation

Important Buying Mistakes
Buying the LKC-1000S+ 2nd for CO₂
The LKC-1000S+ 2nd does not list CO₂ as one of its primary parameters. Choose the M2000 2nd if CO₂ is required.
Buying the M2000 2nd for TVOC
TVOC is not listed as a primary M2000 2nd measurement. Choose the LKC-1000S+ 2nd when TVOC screening is required.
Confusing M2000 2nd With M2000C 2nd
These are different Temtop models. Confirm the full model name before ordering.
Assuming More Parameters Always Mean Better Performance
Choose according to the application, not simply the number of values shown.
Treating the Monitor as an Air Purifier
Both instruments measure pollutants. Neither removes particles or gases from the room.
Final Recommendation
For haze plus ventilation and occupancy monitoring, choose:
Temtop M2000 2nd
For haze plus HCHO and TVOC screening, choose:
Temtop LKC-1000S+ 2nd
For PM2.5 haze and air purifier testing only, either model can perform the main measurement. The final choice should depend on whether CO₂ or TVOC is more valuable to the user.
