FABISENSE PTH-253N Plug-In CO2 Monitor and Alarm Buying Guide Malaysia
FABISENSE PTH-253N Plug-In CO2 Monitor and Alarm Buying Guide Malaysia
Content
The FABISENSE PTH-253N CO2 Monitor and Alarm combines a numerical carbon dioxide display, audio-visual alerts and plug-in or portable operation.
According to the supplied manufacturer catalogue, it offers a 400–5000 ppm CO2 measurement range, a 2.0-inch IPS display and a built-in 1000 mAh lithium battery.
For buyers in Malaysia, it is an option to consider when a visible CO2 reading and an on-device alert are the main requirements.
What Does the FABISENSE PTH-253N Measure?
The product heading, feature list and measurement table identify carbon dioxide - CO2 as the documented measurement.
The page also contains a “CO & CO2 Detector” caption, but provides no CO range or supporting CO specification.
Carbon monoxide detection requires manufacturer confirmation. The PTH-253N should be described as a CO2 monitor based on the available specifications.
Key Features
The supplied catalogue lists:
CO2 measurement from 400–5000 ppm
Numerical CO2 display in ppm
Audio-visual alarm
Buzzer alert
Plug-in and portable operation
Replaceable plug
Built-in 1000 mAh lithium battery
The screen provides a direct reading, while the listed alert function may help users notice a threshold event. Confirm the actual alarm settings before purchase.

The supplied page does not identify the CO2 sensor technology, response time or calibration procedure. NDIR sensing should not be claimed without model-specific confirmation.
Understanding the Accuracy and Resolution Entry
The table prints ±(50 ppm + 5%) under a heading labelled “Resolution”.
This resembles an accuracy expression rather than a display increment. However, the percentage basis and test conditions are not defined.
Request a corrected datasheet confirming both accuracy and resolution. Do not interpret this entry as a 50 ppm display resolution or assume the percentage is calculated from the reading.
Plug-In and Portable Operation
The PTH-253N is presented as supporting mains power and a built-in battery.
Plug-in operation may suit a regular monitoring location. Portable operation allows the instrument to be moved, subject to the manufacturer’s operating instructions.
Before ordering, confirm:
Battery runtime
Charging time
Automatic changeover during a power failure
Alarm operation in battery mode
Low battery indication
Battery replacement arrangements
A battery capacity of 1000 mAh does not establish the available operating time.
Audio-Visual Alarm Functions
The catalogue promotes audio-visual alerts and lists a buzzer.
It does not specify:
Alarm concentration thresholds
Activation delays
Adjustable settings
Sound output
Silencing and reset behaviour
The illustrated reading of 2580 ppm is a display example, not a stated recommended alarm threshold.
Ask for the operating manual or a demonstration if alarm behaviour is an important selection criterion.
Applications for Offices and Meeting Rooms
For offices in Puchong, Kuala Lumpur, Johor and Penang, the PTH-253N provides a way to observe CO2 readings during normal room use.
Users may compare readings at different occupancy levels or before and after changes in ventilation arrangements.
For useful comparisons, record room occupancy, ventilation conditions, instrument position and observation time. Keep the device in a representative location and follow its placement instructions.
Applications for Homes and Shared Spaces
The numerical display may suit users who want to check CO2 readings in living rooms, study areas or shared indoor spaces.
Keep the sensing openings unobstructed and avoid repeatedly breathing directly onto the instrument.
For plug-in use, confirm that the available socket position meets the manufacturer’s placement guidance. Convenience of power access alone does not establish a suitable monitoring location.
Plug Configuration for Malaysia
The catalogue lists a replaceable plug without identifying the available plug types.
Specify the required Malaysia-compatible plug in the quotation and confirm the supplied configuration before purchase.
The housing’s flame-retardant description does not establish a particular material rating or hazardous-area approval.
Connectivity and Additional Parameters
The word “Smart” appears in the product heading, but the supplied page does not list Wi-Fi, Bluetooth, Tuya Smart or remote notifications.
It also does not establish:
Data logging or export
Temperature or humidity measurement
PM2.5 or PM10 measurement
Formaldehyde or TVOC measurement
Confirm any additional requirement rather than assuming that functions from other PTH-253 models are included.
Frequently Asked Questions
Does the PTH-253N measure CO2?
Yes. The catalogue specifies a 400–5000 ppm CO2 range.
Does it also measure CO?
The page contains a conflicting caption, but no CO measurement specification. Obtain manufacturer confirmation before selecting it for CO detection.
Can it operate without mains power?
Portable operation and a built-in battery are listed. Runtime and available functions in battery mode require confirmation.
Does it connect to Tuya Smart?
App connectivity is not specified on the supplied page.
Can it record historical readings?
Data logging and storage are not listed.
How does PTH-253N differ from PTH-252N?
The supplied catalogue pages list similar CO2 ranges, screen specifications, battery capacities and dimensions. Request a manufacturer comparison to establish differences in sensors, firmware, alarm settings and housing.
Can it replace a carbon monoxide alarm?
CO detection and CO alarm performance are not established by the supplied specifications. Select a documented CO alarm where that is the requirement.
