Portable Multi-function Composite Gas Analyzer

Product Introduction

The HD-JK90-M6 Handheld Multi-Function Composite Gas Analyzer is used for portable occasions requiring precise detection and analysis of multiple gas concentrations and temperature/humidity measurement. It uses a 3.5-inch high-definition color screen for real-time concentration display and adopts gas sensors based on electrochemical, infrared, catalytic combustion, thermal conductivity or PID photoionization principles from the best brands in the industry, together with a high-precision Swiss capacitive digital temperature and humidity sensor. Advanced circuit design and mature kernel algorithm processing have obtained a number of software copyright patents and appearance patents. The composite analyzer can detect and analyze gas concentration in pipelines, confined spaces and the ambient atmosphere, and can also detect gas leakage; it can detect more than 500 types of gas and can also detect and analyze the purity of various high-concentration single gases whose background gas is nitrogen or oxygen.

Product Features

• Water splash-proof, dust-proof, explosion-proof and shock-proof; intrinsically safe circuit design, antistatic and anti-electromagnetic interference; passed national standard testing and CMC measuring instrument production license certification.
• Protection level IP66 with built-in water-vapor and dust filter, preventing water vapor and dust from damaging the sensor and instrument.
• Built-in pump-suction measurement with fast response; sampling distance greater than 10 m; special gas path design allows direct detection; gas under positive pressure or negative pressure of -0.3 to 2 kg has no effect on the measurement result.
• 3.5-inch high-definition color screen displays real-time concentration, alarm, time, temperature, humidity, storage, communication, printing, battery level and charging status; the menu uses high-definition simulated icons.
• Large-capacity data storage: standard 300,000 data records, with larger capacity customizable; optional USB flash drive or SD card storage supporting real-time storage, timed storage or storage of only alarm data and time; supports local viewing and deletion; data can be uploaded to a computer via USB, infrared or RS232 for analysis, storage and printing.
• Infrared, USB and RS232 interfaces with automatic identification; optional built-in or external wireless infrared printer; printing content includes company name, gas name, date and time, ambient temperature and humidity, concentration data and detection result.
• USB charging interface with over-charge, over-discharge, over-voltage, short-circuit and over-temperature protection; 5-level accurate battery display; supports USB hot plugging.
• Uses an 11,000 mAh large-capacity rechargeable polymer battery for long continuous operation.
• Sound and light alarm, visual alarm, under-voltage alarm and fault alarm with multi-directional alarm status display.
• Alarm value settable; alarm modes selectable including low alarm, high alarm, interval alarm and weighted-average alarm.
• High-precision temperature and humidity measurement (optional) with simultaneous sensor temperature compensation; operating temperature range -40 to 70℃; can detect gas up to 1300℃ (with optional high-temperature sampling cooling filter handle or high-temperature and high-humidity pretreatment system).
• Can detect as low as 0.001 PPM and as high as 99.999%Vol, supporting automatic switching between high and low ranges (please specify when ordering).
• Real-time or timed detection; the pump can be turned off when not detecting to extend operating time.
• Can detect 1 to 18 gases simultaneously, expandable to 18 gases, with free unit switching; units selectable: PPM, mg/m³, Vol%, LEL%, PPHM, ppb, mg/L.
• Three switchable display modes: simultaneous display of four gas concentrations, large-font cyclic display of single-channel gas concentration, and real-time curve; automatic or manual cyclic switching between channels; whether to display the maximum value, minimum value and gas name can be set; historical record curves can be viewed.
• Chinese and English interfaces selectable, with Chinese as the default.
• Data recovery function with selective or full recovery; misoperation of concentration calibration is automatically identified and blocked.
• Automatic zero tracking and multi-level calibration of target points, ensuring linearity and accuracy and meeting both national standards and local metrology bureau standards.
• Calibration log, maintenance log, troubleshooting countermeasures, sensor life expiration reminder and next calibration time reminder can be recorded.
