ERANNTEX Harmful Gas Diffusion Type Explosion-proof Detector
Brand: ERANNTEX
Specifications
SKU: ERANNTEX Harmful Gas Diffusion Type Explosion-proof Detector
Eranntex Harmful Gas Diffusion Type Explosion-proof Detector Features:
● Splashproof, dustproof, explosion-proof, and shockproof, with intrinsically safe circuit design, anti-static and anti-electromagnetic interference, and passed national standard testing and CPA measuring instrument type certification.
● IP65 protection rating
● 2.31-inch high-definition color screen displays real-time concentration, alarm, time, temperature, humidity, storage, communication, battery level, and charging status. The menu interface uses high-definition realistic icons to display the function names of each menu.
● Large data storage capacity, with a standard capacity of 100,000 data entries. Supports real-time and timed storage, or storage of only alarm concentration data and time. Data can be viewed and deleted locally, and uploaded to a computer via USB for analysis, storage, and printing using host software.
● USB charging port, overcharge, over-discharge, overvoltage, short-circuit, and overheating protection, and 5-level accurate battery level display.
● Powered by a 3000mAh rechargeable polymer battery, it provides long-term continuous operation.
● Audible and visual alarms, vibration alarms, visual alarms, undervoltage alarms, fault alarms, and shutdown alarms. ● Alarm levels can be set, with low, high, and range alarm modes available.
● Optional simultaneous detection of 1 to 4 gases, with freely selectable units: PPM, mg/m³, Vol%, LEL%, PPHM, ppb, and mg/L.
● Three display modes are available: simultaneous display of four gas concentrations, large-font, single-channel gas concentration display, and real-time curves. Automatic or manual cycling between channels is available. Display of maximum and minimum values, gas names, and historical records can be set.
● English and Chinese interfaces are available, with the default being Chinese.
● Data recovery function.
● Automatic zero tracking ensures long-term use without zero drift.
● Multi-level calibration.
● Automatic detection and prevention of concentration calibration errors.
● OEM and ODM customization supported, with optional RS485 communication.
● Optional ambient temperature and humidity measurement. Additional functions and communication interfaces are available.
