Portable EX Gas Detector with Alarm

Introduction of Portable EX Gas Detector with Alarm

The Eagle-CO Portable Gas Detector is an intrinsically safe explosion-proof device for industrial toxic gas monitoring. Compliant with GB3836-2010 and JJF 1421-2013 standards, it carries an Ex ia IIC T4 Ga explosion-proof rating, suitable for IIC-class explosive hazardous environments.

 

Supporting both portable and fixed installation, it continuously monitors carbon monoxide concentration in tunnels, workshops and other industrial sites. Adopting high-precision electrochemical sensors, it displays real-time gas concentration digitally. When readings exceed preset limits, it triggers triple sound, light and vibration alarms for timely safety alerts. Weighing only 116g, the lightweight device is ideal for on-site safety inspectors and workers.It fits harsh working conditions, operating stably at -20℃ to 55℃ with up to 98% relative humidity. Featuring an IP68 high protection grade, it resists dust, water splashes and complex environmental interference.

 

Feature of Portable EX Gas Detector with Alarm

1) Precise and Reliable Detection

It covers a 0–2000ppm CO detection range, with ±10%FS indication error and ±1ppm alarm error. The response time is within 45 seconds, enabling fast gas concentration detection. The sensor lasts over 2 years, and the device supports 2-year continuous operation, lowering long-term maintenance and replacement costs.

 

2) Comprehensive Intelligent Alarm System

It supports customizable dual-level concentration alarms, plus STEL and TWA alarm functions with full-range adjustable thresholds. Boasting a 90+dB alarm sound and 20-meter visible alarm light in darkness, the triple alarm design eliminates missed warnings in noisy or dim industrial scenarios for full safety coverage.

 

3) User-Friendly Intelligent Configuration

Equipped with one-key zero calibration, standard gas calibration and automatic calibration reminders, it ensures long-term detection accuracy. A 4-digit password prevents misoperation. It supports automatic data storage and infrared data export for traceable safety records, with flexible settings for time, date and calibration cycles.

 

4) High Safety & Durability

Built with intrinsic safety circuits and dedicated intrinsically safe batteries, it forbids battery replacement and charging in hazardous areas to avoid explosion risks. Compact and sturdy (95mm×53mm×30mm), it withstands -40℃ to 60℃ storage temperatures, adapting to tough transportation and storage conditions.

FAQ about Portable EX Gas Detector with Alarm

Q1: Why cannot the detector turn on?

A1: It is mainly caused by low battery voltage or internal hardware failure. Replace the battery or send it for factory repair; do not disassemble it privately.

 

Q2: How to fix zero drift in clean air?

A2: Place the device in clean air and perform manual zero calibration. A screen "P" indicates successful calibration.

 

Q3: What causes inaccurate detection or no gas response?

A3: Inaccuracy results from overdue calibration or aging sensors. Recalibrate the device regularly; replace the sensor or return it for repair if there is no gas response.

 

Q4: Can I modify internal parameters or components?

A4: No. Private modifications will damage its explosion-proof performance, cause safety hazards and void the warranty.

 

Q5: What are daily maintenance tips?

A5: Avoid impact, extrusion and screen scratches. Prevent long-term exposure to ultra-high CO concentration. Store it in a dry, clean environment and calibrate it regularly.
