Specifications
SKU: ERANNTEX Hydrogen Sulfide Detection Alarm
The Hydrogen Sulfide Detection Alarm is a specialized monitoring device designed for the toxic properties of hydrogen sulfide. It is widely used in scenarios prone to hydrogen sulfide generation, such as chemical processing, wastewater treatment, underground operations, and oil and gas extraction. Its core function is to continuously monitor hydrogen sulfide concentrations in the environment, triggering immediate alarms when levels exceed safety thresholds to prevent personnel poisoning incidents.
Equipped with a high-precision electrochemical sensor, the detection range is customizable (e.g., 0-10ppm to 0-2000ppm), with a minimum reading of 0.001ppm and a T90 response time ≤30 seconds, enabling precise detection of trace leaks. Strictly compliant with national standards like GB 15322.3, it defaults to 10ppm low-level and 20ppm high-level thresholds, supporting independent adjustment of multiple alarm points. Exceeding thresholds triggers 105dB audible/visual + vibration alarms, ensuring clear detection even in noisy or dim environments.
The device design balances portability and durability, weighing just over 100 grams and supporting handheld or waist-mounted use. IP65/IP66 protection rating withstands humid and dusty conditions, while the 3.7V lithium battery delivers over 12 hours of continuous operation per charge. It also features data storage (≥10 million entries) and USB export functionality, facilitating detection record traceability and providing comprehensive safety assurance throughout operations.
Hydrogen Sulfide Detection Alarm Features:
● Splash-proof, dust-proof, explosion-proof, shock-resistant; intrinsically safe circuit design; anti-static and anti-EMC interference; certified by national standards testing and CMC metrological instrument production license
● IP65 protection rating with built-in moisture and dust filters to prevent sensor/instrument damage from humidity and particulates
● Built-in pump-assisted measurement with integrated moisture/dust filters. Optional professional accessories for high-temperature, high-humidity, and high-dust environments. Rapid response; specialized circuit design enables sampling distances exceeding 10 meters.
● 2.31-inch high-definition color display shows real-time concentration, alarms, time, temperature, humidity, storage, communication, battery level, and charging status. Menu interface uses high-definition simulated icons to display function names.
●Large-capacity data storage supporting 100,000 entries, with customizable higher capacities. Supports real-time storage, scheduled storage, or storage of alarm concentration data and timestamps only. Data can be viewed and deleted locally or uploaded via USB to a computer for analysis, storage, and printing using host software.
● USB charging port compatible with computers or power banks, also compatible with mobile phone chargers. Features overcharge, over-discharge, overvoltage, short-circuit, and overheat protection. 5-level precise battery level display. Supports USB hot-swapping; detector operates normally while charging. Optional RS485 communication.
● Equipped with a 4600mAh high-capacity rechargeable polymer battery for extended continuous operation.
● Multi-sensory alarms: audible/visual/vibration alerts, low-voltage warnings, and fault notifications. Comprehensive alarm status display during alerts.
● Configurable alarm thresholds with selectable modes: low alarm, high alarm, range alarm, weighted average alarm
● High-precision temperature/humidity measurement (optional), with sensor temperature compensation. Operating range: -40°C to 70°C. Detects gases up to 400°C; higher-temperature gas detection available upon request (Optional high-temperature sampling cooling filter handle or high-temperature/humidity pre-treatment system)
● Supports simultaneous detection of 1–4 gases with freely switchable units. Standard gases require no molecular weight input; special gases automatically calculate and switch units upon molecular weight input. Selectable units: PPM, mg/m³, Vol%, LEL%, PPHM, ppb, mg/L
● Three display modes: Simultaneous display of four gas concentrations, large-font cyclic display of single-channel gas concentration, real-time curve. Automatic or manual cycling between channels. Configurable display of max/min values, gas names, and historical curve charts.
● Selectable Chinese/English interface (default Chinese). Concise Chinese or English operation prompts.
● Data recovery function allows selective or full restoration, eliminating concerns over accidental operation errors.
● Automatic zero tracking ensures long-term operation unaffected by zero drift.
● Three-level target point calibration guarantees measurement linearity and accuracy, simultaneously meeting national standards and local metrology bureau requirements.
●Automatically detects and prevents incorrect concentration calibration operations, minimizing human-induced errors.
●Supports real-time or scheduled detection (for low gas concentrations), with pump shutdown during non-detection periods to extend operational lifespan.
●Records calibration logs, maintenance logs, and troubleshooting measures; includes sensor lifespan alerts and next concentration calibration reminders.
