FABISENSE PTH-281AW, PTH-281BW and PTH-281CW Smart Air Detector Buying Guide Malaysia
FABISENSE PTH-281AW, PTH-281BW and PTH-281CW Smart Air Detector Buying Guide Malaysia
Content
The FABISENSE PTH-281 series offers three smart detector configurations with different gas measurement functions. Choose PTH-281AW for carbon monoxide, PTH-281BW for combined carbon monoxide and carbon dioxide, or PTH-281CW for formaldehyde, according to the supplied manufacturer catalogue.
All three models also list temperature, humidity, feels-like temperature and app connectivity. The series page promotes Wi-Fi smart connection, making it important to confirm both the sensor configuration and connected features before ordering.
FABISENSE PTH-281 Model Comparison
The complete model number determines which gas the instrument measures. The shared housing does not mean every version measures CO, CO2 and HCHO.

The feature lists explicitly identify a buzzer alarm for PTH-281CW. Alarm operation for the other variants should be confirmed rather than inferred from the product illustrations.
PTH-281AW - Smart CO Detector
The FABISENSE PTH-281AW is the carbon monoxide configuration.
The catalogue lists:
CO range: 0–1000 ppm
Temperature and humidity
Feels-like temperature
App connection
Magnetic attachment
The stated CO tolerance is ±5 ppm or ±10%, whichever is greater. Confirm the percentage basis and applicable test conditions in the current datasheet.
Before choosing this model for an alarm application, request the alarm thresholds, activation times, sensor life and relevant model-specific documentation.
PTH-281BW - Combined CO and CO2 Detector
The FABISENSE PTH-281BW adds carbon dioxide measurement to the CO function.
Its listed ranges are:
ParameterCatalogue rangeCO0–1000 ppmCO2400–5000 ppm
The catalogue states a CO2 tolerance of ±(50 ppm + 5% of reading).
This configuration may interest buyers who need both gas readings in one compact instrument, together with temperature and humidity.
CO and CO2 are separate parameters. Confirm how the device displays each gas, whether both are monitored continuously and which readings are available through the app.
PTH-281CW - Smart Formaldehyde Detector
The FABISENSE PTH-281CW is the formaldehyde configuration, with a listed HCHO range of 0–2 mg/m³.
Its feature list includes:
Formaldehyde detection
Temperature and humidity
Feels-like temperature
Buzzer alarm
App connection
The table places 0.001 mg/m³ in the tolerance row without an error sign or supporting conditions. This should not be advertised as ±0.001 mg/m³ accuracy.
Request clarification of the actual HCHO accuracy, display resolution, response time and cross-sensitivity information.
Temperature, Humidity and Feels-Like Temperature
The supplied catalogue lists the following shared environmental specifications:
ParameterCatalogue informationTemperature measurement range−10°C to 60°CStated temperature tolerance±1°CHumidity range0–95% RHStated humidity tolerance±5% RH
The series also lists feels-like temperature. The page does not explain its calculation method or applicable range.
If this function matters to your application, confirm how it is calculated and how it differs from the measured air temperature.
Wi-Fi and App Connectivity
The page promotes Wi-Fi smart connection, and the specification table marks app support for all three models.
However, it does not identify:
The app name
Supported Wi-Fi frequency
Remote viewing requirements
Historical data storage
Data export
Push notification functions
Do not assume Tuya Smart compatibility from other FABISENSE products. Confirm the app and available functions for the exact PTH-281 variant supplied.
For office installations, check whether the device can connect to the intended network and whether any account or network configuration is required.
Display, Battery and Dimensions
The three models share the following listed physical specifications:
ParameterCatalogue informationDisplay1.8-inch LCDDisplay resolution360 × 360Battery2100 mAh lithium batteryPower connectionUSB Type-CHousing materialABSWorking temperature−10°C to 50°CDimensions74 × 74 × 32 mm
Battery runtime, charging time and charging input voltage are not stated on the supplied page.
The working temperature range is narrower than the listed temperature measurement range. Confirm permitted operating conditions before using the instrument above 50°C.
Applications for Homes and Offices Malaysia
For buyers in Puchong, Kuala Lumpur, Johor and Penang, model selection should begin with the gas of interest.
PTH-281AW provides the listed CO measurement configuration.
PTH-281BW combines CO and CO2 readings for users who require both parameters.
PTH-281CW provides the listed HCHO measurement configuration for preliminary formaldehyde observations.
Choose a representative location and follow the product manual’s placement and stabilisation instructions. Magnetic attachment, where supplied, provides a mounting option but does not determine a suitable measurement position.
What to Confirm Before Buying
Request the correct model manual and confirm sensor technology, measurement performance, alarm behaviour and connected functions.
The supplied page does not identify the CO, CO2 or HCHO sensor technologies. Electrochemical CO, NDIR CO2 or a particular formaldehyde sensor should therefore not be claimed without supporting documentation.
For a project requiring calibration records, certified alarms or a specified assessment method, verify that the exact model meets those requirements.
Frequently Asked Questions
Which model measures both CO and CO2?
The PTH-281BW lists both gases.
Does PTH-281CW also measure CO2?
CO2 measurement is not listed for PTH-281CW. It is the formaldehyde configuration.
Do these models measure PM2.5 or PM10?
Particle measurement is not listed on the supplied page.
Does the series use Tuya Smart?
The page confirms app support but does not name the app. Tuya compatibility requires confirmation.
Can the app export readings?
Data export and historical storage are not specified.
Are all three models magnetic?
Magnetic attachment is explicitly listed for PTH-281AW and PTH-281BW. It is not specified in the PTH-281CW feature list.
Are the detectors waterproof?
No IP rating is provided. Although the table heading mentions outdoor use, environmental protection must be confirmed before outdoor installation.
