FABISENSE PTH-9R vs PTH-9FW CO, CO2 and Formaldehyde Detector Comparison Malaysia
FABISENSE PTH-9R vs PTH-9FW CO, CO2 and Formaldehyde Detector Comparison Malaysia
Content
The FABISENSE PTH-9R and PTH-9FW combine different gas measurements in compact desktop instruments. The PTH-9R measures carbon monoxide and carbon dioxide, while the PTH-9FW measures formaldehyde and carbon dioxide and adds 2.4 GHz WiFi connectivity.
For buyers in Malaysia, the main decision is the target pollutant. Both models also display temperature and humidity, but their gas-detection functions are different.

Choose the PTH-9R when your requirement includes CO measurement. Choose the PTH-9FW when you need formaldehyde readings alongside CO2, with the listed WiFi connection.
PTH-9R: Combined CO and CO2 Monitoring
The PTH-9R displays separate readings for carbon monoxide and carbon dioxide, allowing users to observe both measurements on one instrument.

The 150 ppm CO and 1500 ppm CO2 values are catalogue default alarm settings. They should not be presented as universal exposure limits or Malaysian regulatory thresholds.
The listed response time also does not, by itself, establish alarm activation timing under every concentration. Request the detailed alarm logic and test conditions where these are important to the application.
PTH-9FW: Formaldehyde and CO2 with WiFi
The PTH-9FW combines HCHO and CO2 measurement, a visual indication bar and a buzzer.

The PTH-9FW range row contains an apparent unit error for CO2. Its display and resolution identify ppm, but the printed range unit should be confirmed before preparing a purchase specification.
The supplied page does not identify the HCHO or CO2 sensor technology. An electrochemical HCHO sensor or NDIR CO2 sensor should not be assumed without further documentation.
Temperature and Humidity Specifications
The environmental measurement ranges differ between the models.

These readings provide context alongside the gas measurements. For consistent room checks, position the detector away from direct sunlight, hot equipment and direct air-conditioner discharge.
Allow the instrument to stabilize after moving it, following the manufacturer's instructions.
WiFi and App Functions on the PTH-9FW
The PTH-9FW is listed for 2.4 GHz WiFi networks, and the catalogue shows Tuya branding.
Before ordering, confirm the exact app and available functions, including:
Remote viewing of supported readings.
Historical graphs and data retention.
Alarm notifications.
Adjustable settings through the app.
Behaviour during a network interruption.
The supplied page does not establish data export, subscription requirements or compatibility with building-management systems.
The PTH-9R page does not list wireless connectivity, so remote access should not be assumed for that model.
Power Supply and Battery Operation
Both instruments list a 3.7 V, 2000 mAh Li-Po battery and a Type-C connection.
The PTH-9R specifies 5 V, 1 A input.
The PTH-9FW prints DC 5 V to DC 24 V maximum. Confirm the approved input and adapter requirements for the exact supplied version before connecting power. The Type-C connector alone does not establish which input voltages are supported.
Battery runtime and charging duration are not stated. For continuous monitoring, ask whether readings, alarms and WiFi remain active while charging and during battery operation.
Choosing for Malaysian Homes and Offices
For a property in Puchong, Selangor or Kuala Lumpur, first identify whether the requirement concerns CO, CO2 or formaldehyde.
The PTH-9R suits selection enquiries involving CO and CO2 together. The PTH-9FW suits enquiries involving HCHO, CO2 and connected viewing.
For facilities buyers in Johor or Penang, also specify whether the instrument must provide documented records, calibrated measurements or certified alarm performance. The supplied page does not establish these capabilities.
Neither model lists PM2.5, PM10, oxygen or combustible gas measurement.
Frequently Asked Questions
Does the PTH-9FW detect carbon monoxide?
CO measurement is not listed. Its advertised gas measurements are formaldehyde and CO2.
Does the PTH-9R measure formaldehyde?
No HCHO measurement is listed for the PTH-9R.
Do both models measure CO2?
Yes. Both list CO2 measurement, although the PTH-9FW range row requires clarification of its printed unit.
Can the PTH-9FW connect to a 5 GHz-only network?
The catalogue specifies 2.4 GHz WiFi only.
Are the PTH-9R alarm settings adjustable?
Adjustable sound-alarm settings are listed for CO and CO2. Confirm the adjustment ranges and alarm behaviour in the manual.
Can these instruments replace a certified CO alarm?
The supplied page does not establish certified CO-alarm compliance. If the application requires a certified alarm, request the applicable documentation and select accordingly.
Is a calibration certificate included?
The catalogue does not state that one is included. Specify any calibration and reporting requirements before purchase.
