Explosion-Proof Portable H2s Gas Analyzer Fixed Hydrogen Sulfide Gas Detector with Price

Covers O2, H2, H2S, CO, CO2, CH4, SO2, NO2, NH3, PH3, O3, CL2, N2, CH2O, and more, with selectable ranges and customization options for each gas type.

Each unit uses high-quality electrochemical sensors sourced from top global manufacturers, paired with Renke's proprietary compensation algorithm for superior sensitivity and repeatability.

Factory calibration uses multi-point standard gas references rather than single-point methods, delivering tighter accuracy, lower zero drift, and better long-term signal stability across all gas varia

Holds both gas-group and dust-group explosion-proof ratings, qualifying the detector for use in Zone 1 and Zone 21 hazardous areas including petrochemical, coal, and metallurgy environments.

Supports infrared remote control for on-site parameter changes, eliminating the need to open the explosion-proof enclosure for configuration adjustments in hazardous area installations.

ModBus-RTU RS485 output supports cable runs up to 2000 meters with configurable address and baud rate, enabling centralized monitoring of distributed detection points across large facilities.

Built-in relay supports direct connection to audible and visual alarms, ventilation interlocks, or emergency shutoff systems without external relay modules or additional wiring components.

Formaldehyde detection reaches 0.01 ppm resolution with accuracy of plus or minus 5% FS at 1 ppm, making it suitable for indoor air quality compliance in factories, warehouses, and furniture facilitie

IP66 protection with a compact wall-mounted design resists high-pressure water jets and dust ingress, maintaining sensor performance in outdoor and washdown-prone industrial environments.

Provides precise installation height recommendations based on gas concentration, ensuring optimal detection location without the need for third-party engineering consultation.
