FABISENSE PTH-4, PTH-5 and PTH-8 CO2 Detector Buying Guide Malaysia
FABISENSE PTH-4, PTH-5 and PTH-8 CO2 Detector Buying Guide Malaysia
Content
The FABISENSE PTH-4, PTH-5 and PTH-8 CO2 detectors offer three configurations for indoor carbon dioxide monitoring. Choose the PTH-4 for CO2 readings, the PTH-5 for CO2 with temperature and humidity, or the PTH-8 for additional Wi-Fi connectivity, Tuya Smart app access and a buzzer alert.
According to the supplied manufacturer catalogue, all three models use an NDIR CO2 sensor and have a 400–5000 ppm CO2 measurement range.
Comparing the FABISENSE CO2 Detectors
The main differences are the additional environmental readings, audible alert and smartphone connectivity.

PTH-4 - Simple CO2 Monitoring
The FABISENSE PTH-4 focuses on carbon dioxide measurement without temperature, humidity or app connectivity.
It is an option for buyers who want to check the CO2 reading directly on the instrument. The catalogue also lists an LED indicator, comfort emoji and low battery alarm.
Choose the PTH-4 when CO2 is the main parameter required and smartphone access is unnecessary.
PTH-5 - CO2, Temperature and Humidity
The FABISENSE PTH-5 adds temperature and relative humidity readings to the CO2 display.
This combination may suit offices, meeting rooms, classrooms and homes where users want several indoor environmental readings on one screen.
The catalogue lists:
Temperature range: −10°C to 40°C.
Stated temperature accuracy: ±1°C.
Humidity range: 20–80% RH.
Stated humidity accuracy: ±5% RH.
Wi-Fi and a buzzer alert are not listed for PTH-5. Select this model when on-device readings meet your requirements.
PTH-8 - Wi-Fi CO2 Monitoring with Tuya Smart
The FABISENSE PTH-8 combines CO2, temperature and humidity measurement with Wi-Fi connectivity and Tuya Smart app support.
The manufacturer catalogue states that users can view historical data and changing trends through the app. This can be useful when observing how readings vary during room occupancy and different ventilation conditions.
Key features listed include:
NDIR CO2 sensor.
CO2, temperature and humidity readings.
2.4 GHz Wi-Fi connectivity.
Tuya Smart app compatibility.
Historical data and trend viewing through the app.
Buzzer alert.
LED indicator and comfort emoji.
The PTH-8 supports 2.4 GHz Wi-Fi networks. Check that a compatible network is available where the detector will be used.
The catalogue does not specify data retention duration, export formats, app notification settings or multi-user access. Confirm these functions before purchase if they are required.
CO2 Measurement Specifications
The supplied catalogue lists the following shared CO2 specifications:
ParameterCatalogue specificationSensor technologyNDIRCO2 measurement range400–5000 ppmCO2 display resolution1 ppmCO2 accuracy notation±(50 ppm ±5%), as printedBattery2400 mAh lithium-ionCharging connectionMicro USBCharging input5 V, 1 AWorking temperature−10°C to 40°CDimensions83 × 83 × 32 mm
The catalogue’s CO2 accuracy notation requires clarification. Ask for the current datasheet to confirm how the 50 ppm and percentage terms apply.
A 1 ppm display resolution does not mean ±1 ppm accuracy. Resolution describes the displayed increment; accuracy describes how closely the reading agrees with a reference under specified conditions.
Applications for Offices and Meeting Rooms
For offices in Puchong, Kuala Lumpur, Johor Bahru and Penang, these detectors provide a way to observe indoor CO2 readings during daily use.
For example, facilities staff can compare readings:
Before and during a meeting.
At different occupancy levels.
Before and after a change in ventilation arrangements.
Across comparable rooms using consistent measurement positions.
The PTH-5 provides additional temperature and humidity readings on the device. The PTH-8 adds app-based history and trend viewing for users who want to review changes over time.
Applications for Classrooms and Training Rooms
Classrooms and training rooms can have changing occupancy throughout the day. A visible CO2 display helps users observe how the measured concentration changes under those conditions.
PTH-4 offers the simplest configuration. PTH-5 adds temperature and humidity, while PTH-8 provides connected monitoring.
For meaningful comparisons, record the room occupancy, ventilation arrangement, instrument position and observation period.
How to Position a CO2 Detector
Choose a representative location.
Avoid placing the detector immediately beside an open window, supply air outlet or other position that may give an unrepresentative reading for the occupied area.
Avoid breathing directly onto the instrument.
Exhaled air can affect the nearby CO2 reading. Allow the instrument to operate in its intended position rather than repeatedly holding it close to your face.
Keep sensor openings unobstructed.
Follow the product manual for clearances, placement and initial stabilisation.
Compare similar conditions.
Use consistent positions and note changes in occupancy or ventilation when comparing readings.
What Does an NDIR CO2 Sensor Mean?
NDIR stands for non-dispersive infrared. It is a measurement method used to detect carbon dioxide through infrared absorption.
The supplied catalogue explicitly lists NDIR CO2 sensors for PTH-4, PTH-5 and PTH-8.
Sensor technology is one selection factor. Buyers should also check accuracy, response time, calibration instructions and long-term maintenance requirements for the intended application.
What These CO2 Detectors Do Not Measure
The supplied page does not list measurement of:
Carbon monoxide - CO
PM2.5 or PM10
Formaldehyde - HCHO
TVOC
Oxygen - O2
A CO2 reading does not provide a complete assessment of indoor air quality. Select additional instruments when your application requires particle or other gas measurements.
These models should also not be described as carbon monoxide alarms.
Frequently Asked Questions
Which model supports Wi-Fi?
The PTH-8 supports 2.4 GHz Wi-Fi. Wireless connectivity is not listed for PTH-4 or PTH-5.
Which app does the PTH-8 use?
The catalogue specifies Tuya Smart.
Can the PTH-8 show historical readings?
Yes. The catalogue states that users can view historical data and changing trends through the app. Data retention and export capabilities require confirmation.
Do all three models have an audible alarm?
No. The comparison table lists a buzzer alert for PTH-8 only. Confirm its thresholds and settings before relying on this feature.
Do PTH-4 and PTH-5 use the same charging connection as PTH-8?
The catalogue lists Micro USB, 5 V, 1 A charging for all three models.
How long does the battery last?
Each model has a listed 2400 mAh battery, but operating time is not stated on the supplied page.
Can these detectors provide formal indoor air quality certification?
The supplied page does not establish suitability for a particular formal assessment method. Where documented compliance is required, confirm the applicable instrument and measurement requirements before purchasing.
