FABISENSE PTH-302B Smart Radon Detector with Tuya WiFi Monitoring Malaysia
Content
The FABISENSE PTH-302B Smart Radon Detector combines radon measurement, an on-device display, data logging and Tuya Wi-Fi connectivity. According to the supplied manufacturer catalogue, it uses a passive diffusion chamber and alpha spectrometry to monitor radon concentration.
For buyers in Malaysia, its main features are historical trend viewing, selectable measurement units, configurable alarm thresholds and dual power options.
What Does the PTH-302B Measure?
The PTH-302B measures radon concentration, with readings available in:
Becquerels per cubic metre - Bq/mÂł
Picocuries per litre - pCi/L
The catalogue gives the conversion as 1 pCi/L = 37 Bq/mÂł.
This is a dedicated radon monitoring product. The supplied page does not list PM2.5, CO, CO2, formaldehyde or TVOC measurement.
Passive Diffusion Chamber and Alpha Spectrometry
The manufacturer lists passive diffusion as the sampling method. This allows surrounding air to enter the measurement chamber without a listed sampling pump.
The stated detection method is alpha spectrometry.
These specifications distinguish the PTH-302B from ordinary indoor air quality monitors that measure particles or other gases. Buyers should request the operating manual for details on initial setup, measurement intervals and calibration arrangements.
Measurement Range and Units
The catalogue lists:
ParameterManufacturer catalogue informationRadon range in pCi/L0–500 pCi/LRadon range in Bq/m³0–20,000 Bq/m³Unit switchingpCi/L and Bq/m³Sampling methodPassive diffusion chamberDetection methodAlpha spectrometry
The two stated range limits are not exact conversions. Using the catalogue’s conversion factor, 500 pCi/L equals 18,500 Bq/m³. Confirm the actual upper measurement limit in each display mode before selecting the instrument for a specified range.
Understanding the Stated Accuracy
The specification table states performance at approximately 5.4 pCi/L or 200 Bq/mÂł:
After seven days: ±10%.
After two months: ±5%.
These are manufacturer-stated figures associated with a reference concentration and measurement duration. They should not be presented as immediate accuracy across the entire measurement range.
Ask for supporting performance documentation if accuracy is important to a project. Also confirm the time required for the first valid reading and how the instrument calculates each average.
Tuya Wi-Fi Monitoring
The PTH-302B is presented as compatible with Tuya Smart, with app-based monitoring, history tracking, alerts and data synchronisation.
This may suit users who want to review readings without relying solely on the instrument’s screen.
Before ordering, confirm:
Supported Wi-Fi frequency
Phone and app compatibility
Remote viewing requirements
Notification settings
Data retention and export options
The supplied page does not specify the Wi-Fi band. Requirements from other FABISENSE models should not be assumed to apply.
Data Logging and Historical Averages
The catalogue lists rolling average views covering:
3 hours, 12 hours, 24 hours, 3 days, 7 days, 30 days, 120 days and 365 days, together with cumulative peak values.
These views can help users compare shorter observations with longer monitoring periods.
A three-hour average and a seven-day average represent different observation periods. Record the averaging period when comparing readings or preparing a monitoring record.
Confirm whether all listed views are available on the device, in the app or both. File export and report generation are not explicitly established by the supplied page.
Audible and Visual Alerts
The catalogue lists audible and visual alarms, together with customisable thresholds.
Its default colour descriptions refer to:
Green: Below 2.7 pCi/L.
Yellow: Between 2.7 and 4 pCi/L.
Red: At or above 4 pCi/L.
Confirm boundary behaviour and available settings in the product manual.
These are manufacturer-listed display settings. Their presence does not establish a Malaysian regulatory threshold or certification.
The promotional app illustration also shows a concentration and status label that appear inconsistent. Treat illustrated readings as mock-ups and verify actual alarm behaviour on the supplied instrument.
Power Supply and Operating Conditions
The supplied specification table lists:
ParameterCatalogue informationDirect power inputUSB Type-C, DC 5 V, 1 ABattery optionTwo 1.5 V AA alkaline batteriesOperating temperature0°C to 40°COperating humidityBelow 85% RHAdditional functionsCalendar, time and multilingual support
Battery runtime and the functions available during battery operation are not stated. Confirm whether Wi-Fi, synchronisation and alarms remain available in that mode.
The page does not state an IP rating. Follow the manual’s environmental restrictions when choosing a location.
Applications for Homes, Offices and Property Monitoring
The PTH-302B may interest homeowners, property managers and facilities teams who need a dedicated instrument for observing radon readings over time.
For a property in Selangor, Kuala Lumpur, Johor or Penang, selection should focus on the monitoring purpose, required observation period and supporting documentation.
A practical monitoring record should identify:
Room and instrument location
Start and end dates
Selected averaging period
Displayed units
Relevant changes in room use or ventilation
Follow the manufacturer’s placement instructions. If the results will support a formal assessment, confirm the required method and instrument acceptance criteria before purchasing.
Frequently Asked Questions
Does the PTH-302B measure radon directly?
The catalogue identifies a passive diffusion chamber and alpha spectrometry as its radon measurement system.
Can it display both Bq/mÂł and pCi/L?
Yes. Dual-unit switching is listed.
Does it support Tuya Smart?
Yes. The supplied page lists Tuya Wi-Fi connectivity and app monitoring.
Is ±5% accuracy available immediately?
No. The table associates the ±5% figure with two months of measurement at the stated reference concentration.
Can it operate from batteries?
The table lists two AA alkaline batteries as a power option. Runtime and connected functions during battery operation require confirmation.
Does it include a five-year warranty?
The catalogue advertises a five-year warranty. Confirm eligibility, coverage, exclusions and the service process for Malaysia in the quotation.
Can the app export a report?
History viewing and data logging are listed, but report export is not clearly specified.
