HA series (HA20/40/71/72): HA20/40 supports 2-4 inputs, HA71/72 supports 16-64 inputs, provides relay output and Modbus communication, suitable for small and medium-sized monitoring systems.
Accessories and Calibration Equipment
Calibration kit: specialized calibration tools for different products (such as XNXTOXKit, XCDCOMBKit), including flow meters, tubing, pressure reducing valves, etc., to ensure calibration accuracy.
Installation accessories: pipe supports, sunshades, rain covers, junction boxes, etc., suitable for different installation environments (such as high temperature, humidity, explosion-proof areas).
Alarm device: Sound and light alarm (such as SpectraAlert series), supporting multiple light intensities and sound levels, suitable for sound and light warnings in hazardous areas.

Technical features and advantages
Detection performance: Using various principles such as electrochemistry, catalytic beads, infrared, etc., it covers combustible gases (0-100% LEL), toxic gases (ppm level), oxygen (0-25% Vol) and flames, with fast response time (T90 generally<60 seconds) and high accuracy (± 1.5% LEL or ± 3ppm).
Environmental adaptability: The shell material is mostly 316 stainless steel or epoxy coated aluminum alloy, with IP66/67 protection, a wide working temperature range (-40 ℃ to+150 ℃), vibration resistance, corrosion resistance, and suitable for harsh industrial environments.
Usability: Non invasive operation (magnetic switch), Bluetooth configuration (some models), plug-in sensor replacement, reducing maintenance costs; Equipped with LCD display and status indicator lights for easy on-site inspection.
Communication and Integration: Supports 4-20mA, Modbus, HART, Foundation Fieldbus, etc., seamlessly integrates with PLC and DCS systems, and enables remote monitoring and data traceability.
Complete certification: Passed major global certifications such as UL, CSA, ATEX, IECEx, CCCF, etc., to meet safety regulations in different regions.

Application scenarios
Petrochemical industry: monitoring of combustible gas (methane, propane) and toxic gas (H ₂ S, Cl ₂) leaks in refineries and chemical plants.
Power industry: SF ₆ and H ₂ testing for gas turbine engine rooms and substations.
Manufacturing industry: VOCs detection in painting workshops and solvent vapor detection in spray painting rooms; Flame monitoring in the welding area of the automobile factory.
Storage and Logistics: Monitoring of toxic gases such as ammonia and chlorine in hazardous goods warehouses.
Semiconductor industry: Special gas (AsH ∝, PH ∝, NF ∝) leak detection.
Precautions
Regulations and standards: The product must comply with local safety regulations (such as NFPA, EN standards), and it is recommended to regularly check the latest regulatory requirements.
Calibration and maintenance: Regularly calibrate according to the manual (usually every 6 months), using certified calibration gases; High pollution environments require increased maintenance frequency.
Installation specifications: Installation in hazardous areas must comply with explosion-proof requirements, and sensor positions should avoid dead corners of airflow, high temperature sources, or vibration sources.
Data update: Product parameters and certifications may be updated. It is recommended to obtain the latest datasheet through the official website. This guide does not constitute a contractual basis.
