Bosean K-600 Built-in Pump 4 in 1 Multi Gas Detector is a professional portable multi-gas detection instrument designed for simultaneous monitoring of up to four gases in industrial, marine, petroleum, chemical, environmental, confined-space, and hazardous-area applications.
The K-600 combines a built-in pump suction sampling system, high-sensitivity gas sensors, colour LCD display, audible and visual alarms, vibration alerts, gas concentration curve display, and data recording in a compact and rugged portable instrument.
The detector can be configured to detect four gases simultaneously according to the customer’s selected sensor combination. Common configurations include oxygen (O₂), carbon monoxide (CO), hydrogen sulfide (H₂S), and combustible gas such as methane (CH₄/LEL). Other supported gases can be specified according to the required application and sensor configuration.
The K-600 uses a gas pump sampling method to draw atmospheric samples into the instrument. Its high-sensitivity sensors provide gas concentration measurement with a stated accuracy of ≤ ±5% F.S. and response time of ≤30 seconds.
The Bosean K-600 operates using a built-in pump suction sampling principle. The integrated pump draws air or gas samples from the surrounding atmosphere or through a connected sampling line and directs the sample into the installed gas sensors.
Each sensor measures the concentration of its assigned gas. The detector processes the sensor signals and displays the measured concentrations and system status on the CSTN colour LCD.
Depending on the selected configuration, the K-600 can simultaneously monitor four gases. A commonly specified configuration is CH₄/LEL, O₂, CO, and H₂S, making the instrument suitable for many applications involving combustible and toxic-gas monitoring as well as oxygen-deficiency detection.
The detector provides LED, audible, and vibration alarms for gas leakage, instrument faults, low battery voltage, and pump operating status. This gives operators multiple warning methods when hazardous conditions are detected.
The K-600 also supports gas concentration curve display and data recording, allowing measurement information to be monitored and retained for later review and analysis. Bosean specifies storage for up to 1,200 records, with computer connectivity through dedicated software.

The Bosean K-600 is a professional portable 4-in-1 multi-gas detector with built-in pump designed for monitoring combustible, toxic, and oxygen-related atmospheric hazards in demanding industrial environments.
By combining pump-suction sampling, high-sensitivity gas sensors, real-time display, multiple alarm methods, gas concentration curve monitoring, and data recording, the K-600 provides a practical solution for portable atmospheric monitoring.
The detector can be configured for different four-gas combinations. A commonly specified configuration is oxygen (O₂), carbon monoxide (CO), hydrogen sulfide (H₂S), and combustible gas/LEL, providing simultaneous monitoring of oxygen concentration, toxic gases, and combustible-gas hazards.
Bosean also lists additional sensor options for the K-600 platform, including CH₄, C₃H₈, H₂, NH₃, NO, PH₃, NO₂, HCN, SO₂, Cl₂, O₃, CO₂, HCl, HF, VOC-related gases, and other supported gases. The exact gas combination must be specified according to the customer’s application and ordered sensor configuration.
The built-in pump draws the atmospheric sample through the sampling system and delivers it to the installed sensors. This pump-suction arrangement makes the K-600 suitable for applications where atmospheric samples need to be drawn from confined, enclosed, remote, or difficult-to-access locations.
The K-600 provides a stated measurement accuracy of ≤ ±5% F.S. and a response time of ≤30 seconds, depending on the selected sensor. Actual performance varies according to the gas sensor and application conditions.
The detector’s CSTN colour LCD provides real-time measurement information and system status. The gas concentration curve display allows operators to observe changes in gas concentration during the monitoring process.
For operator safety, the K-600 provides LED, audible, and vibration alarms. These warnings can indicate gas leakage, equipment faults, low battery voltage, and pump operating status, helping personnel respond quickly to changing atmospheric conditions.
The K-600 incorporates a data-recording function capable of storing up to 1,200 records. Stored information can be connected to a computer through the manufacturer’s software for data management, printing, and analysis.
The detector is constructed using high-strength engineering plastics and compound anti-slip rubber, providing a rugged and portable enclosure. Bosean specifies waterproof, dustproof, and explosion-proof construction for the K-600. The published explosion-protection grade is Ex ib IIC T4 Gb.
The K-600 has an approximate weight of 400 g including the battery and dimensions of approximately 130 mm × 67 mm × 30 mm, providing a compact form factor for personal and portable gas-monitoring operations.
Bosean specifies a 3.7 V, 3200 mAh lithium-ion battery for the K-600. The published technical information states a working time of ≥8 hours continuously without alarming, with a charging time of approximately 6–8 hours.
The K-600 is suitable for a broad range of applications including petroleum, refinery operations, chemical facilities, environmental protection, metallurgy, gas transmission and distribution, biochemical applications, underground storage tanks, oil rigs, sewers, waterworks, and maritime tank and confined-space operations.
With the advanced design of the Fanbeam 5 laser unit, custom reflectors, and the Fanbeam Controller 4.0 software, Fanbeam has become the preferred laser-based PRS. Its wide range of data outputs and seamless integration with other sensors and DP systems make it ideal for holding a vessel in position or for executing precise movements.
