FABISENSE PTH-22 Series Portable HCHO, Gas, CO2 and CO Detector Buying Guide Malaysia
FABISENSE PTH-22 Series Portable HCHO, Gas, CO2 and CO Detector Buying Guide Malaysia
Content
The FABISENSE PTH-22 series consists of four separate portable detector models for different gases. Choose PTH-22A for formaldehyde, PTH-22B for combustible gas, PTH-22C for carbon dioxide or PTH-22D for carbon monoxide, according to the supplied manufacturer catalogue.
These are individual detector configurations. One instrument is not listed as measuring all four gases.
Each model features a compact handheld design, a numerical display, a buzzer alert and a low battery alarm.

For PTH-22B, the relationship between the printed ppm and %LEL ranges requires clarification. Confirm the calibration gas and conversion basis before interpreting the readings.
PTH-22A - Portable Formaldehyde Detector
The FABISENSE PTH-22A is the formaldehyde configuration.
The catalogue lists:
HCHO range: 0–3.000 mg/m³
HCHO resolution: 0.001 mg/m³
Buzzer alert
Low battery alarm
Its handheld format may interest buyers who need a portable HCHO display for preliminary observations in homes, offices or property interiors.
The catalogue does not state HCHO accuracy. A resolution of 0.001 mg/m³ does not establish an accuracy of ±0.001 mg/m³.
Before selecting this model for a defined measurement task, request the sensor type, response time, cross-sensitivity information and calibration instructions.
PTH-22B - Portable Combustible Gas Detector
The FABISENSE PTH-22B is listed as a combustible gas detector.
The specification table gives:
Gas range: 1–20% LEL
Additional printed range: 100–10,000 ppm
Resolution: 100 ppm / 1% LEL
Stated accuracy: ±3% LEL
The supplied page does not identify the target or calibration gas. Compatibility with methane, propane, butane or a particular LPG mixture must be confirmed.
The catalogue also does not establish a flexible probe, gas-specific selectivity or a leak-rate measurement function. Confirm these requirements if the intended task is locating a leak.
PTH-22C - Portable CO2 Detector
The FABISENSE PTH-22C measures carbon dioxide within a listed range of 400–5000 ppm, with a 1 ppm display resolution.
It may suit buyers who want to observe CO2 readings at different indoor locations without selecting a larger desktop monitor.
For useful comparisons in offices, meeting rooms or classrooms, record:
Instrument position
Room occupancy
Ventilation conditions
Observation time
Avoid breathing directly onto the instrument during measurement, and follow the manual’s stabilisation instructions.
The catalogue prints a CO2 accuracy expression involving 50 ppm and 5%, but does not clearly define the percentage basis. Confirm the complete specification before quoting measurement accuracy.
The CO2 sensor technology is not identified on this page. NDIR sensing should not be assumed from other FABISENSE products.
PTH-22D - Portable CO Detector
The FABISENSE PTH-22D is the carbon monoxide configuration.
The catalogue lists:
CO range: 0–500 ppm
CO resolution: 1 ppm
Stated CO accuracy: ±10%
Buzzer alert
Low battery alarm
Ask for the accuracy conditions, response time and alarm activation details before choosing this model for a particular application.
A listed buzzer does not establish certified residential CO alarm performance. Where a certified alarm or occupational instrument is required, request documentation covering the exact model.
Battery Power and Operating Temperature
The supplied catalogue lists the following shared information:

Battery runtime, product dimensions and an IP rating are not provided on this page.
These models should not be advertised as USB rechargeable. Follow the manual’s battery requirements and replacement instructions.
Choosing the Right Detector in Malaysia
For buyers in Selangor, Kuala Lumpur, Johor and Penang, start with the specific gas required.
Choose PTH-22A when the requirement is formaldehyde measurement.
Choose PTH-22B when combustible gas detection is required, after confirming the intended gas and calibration.
Choose PTH-22C when the requirement is carbon dioxide measurement.
Choose PTH-22D when the requirement is carbon monoxide measurement.
If the task requires several gases simultaneously, select an instrument explicitly configured for those gases rather than relying on the series name.
What to Confirm Before Ordering
Request the correct model manual and confirm sensor technology, response time, alarm thresholds and calibration arrangements.
For the PTH-22B, also confirm gas compatibility and the ppm-to-%LEL relationship. For PTH-22A and PTH-22C, obtain clarification of the missing or ambiguous accuracy information.
Wi-Fi, Bluetooth, app support, data logging and export are not listed on the supplied page. Confirm separately if any of these functions are required.
Frequently Asked Questions
Does one PTH-22 detector measure HCHO, combustible gas, CO2 and CO?
No. The catalogue presents four separate models, each assigned a different measurement.
Does PTH-22A also measure TVOC?
TVOC measurement is not listed for PTH-22A.
Can PTH-22B detect LPG?
The page describes combustible gas detection but does not identify supported gases. Confirm suitability for the intended LPG composition before purchase.
Does PTH-22C measure carbon monoxide?
CO measurement is not listed for PTH-22C. PTH-22D is the CO configuration.
Do these detectors measure temperature and humidity?
Temperature and humidity measurement functions are not listed on this page. The working temperature specification describes operating conditions.
Can they replace a confined-space multi-gas detector?
The supplied specifications do not establish that capability. Oxygen measurement, simultaneous multi-gas monitoring and intrinsic safety certification are not listed.
