FABISENSE PTH-28A vs PTH-28B Neptune Portable CO and CO2 Monitor Malaysia
Content
The FABISENSE PTH-28 Neptune series combines carbon monoxide, carbon dioxide, temperature, humidity and a UV index indication in a portable monitor.
Both the PTH-28A and PTH-28B list a 1.8-inch touchscreen, an aluminium-alloy housing and a rechargeable battery. The main differences are app connectivity, time display and wireless charging, which are listed for the PTH-28B.
For buyers in Malaysia, choose according to the required viewing method, charging arrangement and documentation for the intended application.

CO and CO2 Measurement Specifications
The catalogue lists matching gas-measurement specifications for both models.
ParameterPublished specificationCO range0-1000 ppmCO accuracy±5 ppm or ±10%, whichever is greaterCO2 range400-5000 ppmCO2 accuracy±(50 ppm + 5% of reading)CO and CO2 resolutionNot specified
The supplied page repeats the accuracy information under a separate “Tolerance” row. It does not provide response times, calibration procedures or detailed alarm thresholds.
Before purchase, confirm the sensor specifications and performance conditions that apply to the exact supplied version.
Two Gas Readings on One Display
The illustrated interface displays CO and CO2 separately, with temperature and humidity information alongside them.
This arrangement allows users to observe several parameters without switching between separate instruments. However, CO and CO2 are different measurements and should be interpreted independently.
The page does not list combustible gas, smoke, oxygen or formaldehyde detection. These functions should not be assumed from the “multifunctional air monitor” description.
Temperature, Humidity and Operating Conditions
ParameterCatalogue specificationTemperature measurement-10°C to 60°CTemperature accuracy±1°CHumidity measurement0-95% RHHumidity accuracy±5% RHWorking temperature-10°C to 50°CUV indicationIndex levels 1-11
The working-temperature range is narrower than the listed temperature-measurement range. Use the operating limits when assessing installation suitability and request clarification where necessary.
The catalogue does not identify whether the UV indication comes from a dedicated sensor, a calculation or connected data. Confirm its source, accuracy and availability on each model.
Touchscreen and Portable Construction
Both models list a 1.8-inch LCD touchscreen with 360 x 360 resolution.
The published body dimensions are 79.5 x 74 x 30 mm, with a listed weight of 151 g. An aluminium-alloy case and hanging arrangement support the portable design.
The bezel shows compass-style markings, but the specification does not establish an electronic compass function. Confirm any navigation-related capability separately.
PTH-28B Bluetooth App Connection
The promotional panel advertises Bluetooth app connectivity, while the comparison table assigns app support to the PTH-28B.
Before selecting it, confirm:
The exact app name and supported phone versions.
Available live readings.
History retention and export functions.
Whether records continue while the phone is disconnected.
Alarm-setting and notification options.
Supported connection distance.
The supplied page does not establish direct WiFi connectivity or remote access beyond Bluetooth range.
Battery and Charging Options
Both models list a 2100 mAh battery and Type-C charging. The PTH-28B additionally lists wireless charging.
Battery runtime, charging time and input ratings are not provided. Confirm the approved adapter and whether a wireless charging accessory is included.
Also establish whether measurement continues during charging and whether app use changes the expected operating duration.
Outdoor Use and Protection Claims
The catalogue advertises outdoor use and includes a waterproof icon. It does not provide an IP rating or defined water-exposure conditions.
For enquiries involving camping or outdoor activities in Selangor, Johor or Pahang, request the protection rating and instructions covering rain, condensation, dust and charging-port protection.
The supplied page does not establish intrinsic safety, hazardous-area approval or certified residential CO-alarm compliance. Include these requirements explicitly if they are necessary for the application.
Alarm Behaviour Requires Confirmation
Warning symbols and speaker icons appear in the illustrations, but the page does not specify sound level, activation thresholds or alarm delays.
Request the model-specific alarm instructions before relying on the warning functions. Displayed example readings should not be interpreted as alarm setpoints.
