CO Gas Detector Malaysia Fosensor FS11301 4-in-1 Gas Detector
CO Gas Detector Malaysia Fosensor FS11301 4-in-1 Gas Detector When carbon monoxide is one of the gases that needs to be monitored, users can choose between a dedicated CO detector and a multi-gas detector. For industrial applications where users also need to monitor hydrogen sulphide, oxygen and combustible gas, the Fosensor FS11301 Portable 4-in-1 Gas Detector combines: CO + H2S + O2 + EX/LEL in one portable instrument. The FS11301 is available in both Natural Diffusion and Pump Suction configurations, providing different sampling options for professional industrial gas monitoring. What Is the CO Range of the Fosensor FS11301? The FS11301 provides: CO Measuring Range: 01000 ppm Resolution: 1 ppm The manufacturer's listed CO alarm points are: Low Alarm: 50 ppm High Alarm: 150 ppm CO is monitored simultaneously with the detector's H2S, O2 and EX channels. What Other Gases Does the FS11301 Detect? The standard FS11301 configuration covered by the manufacturer's documentation provides: GasMeasuring RangeResolutionCO01000 ppm1 ppmH2S0100 ppm1 ppmO2030% VOL0.1% VOLEX0100% LEL1% LEL This is an important distinction when comparing the FS11301 with a CO-only detector. The FS11301 is designed as a 4-in-1 gas detector, not simply a carbon monoxide meter. CO Detector or 4-in-1 Gas Detector? The correct choice depends on the gases that actually need to be monitored. Choose a Dedicated CO Detector When: The requirement is specifically carbon monoxide monitoring and the additional gas channels are unnecessary. Consider Fosensor FS11301 When: The monitoring requirement includes: CO + H2S + O2 + LEL This allows four parameters to be checked with one portable detector. Why Isn't CO Monitoring Alone Always Enough? A CO reading provides information about carbon monoxide concentration. It does not provide: Oxygen concentration H2S concentration Combustible-gas / LEL concentration Where these additional atmospheric hazards have also been identified, a four-gas detector provides a broader monitoring solution. The gases required should always be determined according to the actual application. What Is the FS11301 CO Alarm Setting? The manufacturer's specification lists: CO Low Alarm: 50 ppm CO High Alarm: 150 ppm These are the values stated in the FS11301 documentation. Users should not assume that manufacturer-listed alarm points automatically satisfy every workplace requirement. Alarm parameters should follow the applicable workplace safety procedure. Natural Diffusion Version The Fosensor FS11301 Natural Diffusion version allows surrounding gas to reach the sensors naturally. Specified dimensions: 135 × 68 × 43 mm This configuration sould be considered when professional four-gas monitoring is required but the user's procedure does not require active sampling. Pump Suction Version The Fosensor FS11301 Pump Suction version incorporates an active sampling pump. Specified dimensions: 150 × 68 × 60 mm The pump actively draws the gas sample toward the detector. This version should therefore be considered when active sampling is required by the testing procedure. Do I Need a Pump for CO Detection? Not necessarily. The need for Pump Suction depends on the required sampling method, not simply on the gas being measured. If the detector is monitoring the surrounding atmosphere and active sampling is not required, Natural Diffusion may be appropriate. If the procedure requires gas to be actively drawn toward the detector, the Pump Suction version should be considered. Can the Pump Version Also Work as Natural Diffusion? The FS11301 manual describes a procedure for changing the Pump Suction configuration to Natural Diffusion. The procedure includes: Removing four screws from the rear. Removing the pump suction module. Installing the Natural Diffusion front cover. Re-tightening the screws. The detector can then operate in Natural Diffusion mode. This gives the Pump version additional flexibility for users with different sampling requirements. How Does FS11301 Alert the User? The detector provides several warning methods: Audible alarm LED indication Vibration Backlight LCD alarm information When an alarm condition occurs, the FS11301 can activate the buzzer, flashing red indicator, backlight and vibrator. This gives the operator several simultaneous warning indications. Does the FS11301 Have STEL and TWA? Yes. According to the FS11301 manual, its alarm menu provides settings for: Low Alarm High Alarm STEL TWA MAX These functions give professional users additional monitoring parameters beyond a basic instantaneous CO reading. The applicable limits should be established according to workplace requirements. Can the FS11301 Store CO Alarm Records? The FS11301 provides a gas alarm record function. Users can select a gas type and display the corresponding record. This allows the operator to review the relevant gas record directly through the detector interface. Does FS11301 Display Gas Trends? Yes. The detector provides a Curve Graph function. Users can browse changes in the measured parameters through the instrument interface. This provides additional information beyond the current real-time numerical display. How Fast Is the FS11301? The manufacturer's general performance specification states: Response Time: T < 15 seconds The specified display error is: ≤ ±2% FS The manufacturer's document does not provide a separate response-time figure specifically for the CO channel, so the general T<15s specification should not be represented as an independently specified CO-only response time. What Sensor Technology Does FS11301 Use? The manufacturer's performance table lists the working principles as: Electrochemical and Catalytic Combustion The supplied documentation does not separately map every individual gas channel to its sensor technology. Therefore, individual sensor claims should follow the manufacturer's detailed specification if required for a tender or technical submission. Where Is the Fosensor FS11301 Used? The manufacturer lists main applications including: Petroleum Chemical Industry Environmental Protection Metallurgy Refining Gas Transmission and Distribution Biochemical Pharmaceuticals Agriculture This positions the FS11301 primarily as an industrial multi-gas detector. Is FS11301 a Home Carbon Monoxide Alarm? The FS11301 documentation describes a portable industrial 4-in-1 gas detector. It should not be presented as a domestic fixed CO alarm based on the supplied documentation. Its positioning is professional portable gas monitoring, with four simultaneous gas channels and industrial functions such as STEL, TWA, alarm records and Pump Suction availability. Can FS11301 Detect CO in a Factory? The FS11301 has a specified CO measuring range of: 01000 ppm However, whether it is suitable for a particular factory application depends on the gases identified as hazards, required measuring range, sampling procedure and applicable workplace requirements. The FS11301 should therefore be selected based on the application rather than simply because CO may be present. Can FS11301 Detect Every Toxic Gas? No. The standard configuration described here detects: CO + H2S + O2 + EX/LEL It should not be assumed to detect every toxic gas. If ammonia, chlorine or another specific gas needs to be measured, a detector with the appropriate sensor should be selected. Tell MTM Precision the gas you need to detect before ordering. Battery Capacity and Runtime The FS11301 uses a: 3000mAh lithium battery The manufacturer specifies: Standby Time: >8 hours Charging Time: approximately 4 hours Working Voltage: DC 5V The detector uses a Type-C connection for charging. Important Charging Precaution The manufacturer's manual states that the detector should not be charged at the testing site where sparks from plugging or unplugging the charger could create a fire or explosion hazard. The battery pack must also not be charged in an explosive gas atmosphere. Users should follow the manufacturer's operating instructions. Does a CO Gas Detector Need Calibration? For the FS11301, the manufacturer states that the detector should be periodically calibrated. The manual specifies: Calibration cycle should not exceed one year. The calibration menu includes: Zero-point calibration Zero-point shift Concentration calibration One-click zeroing Factory reset The manufacturer warns that calibration functions are intended for professionals because incorrect calibration can affect test results.
