Portable Odor Gas Analyzer

I. Product Overview

This device is a portable mobile testing instrument specially designed for on-site detection of odor OU as well as typical odorous gas concentrations such as dimethyl sulfide, dimethyl disulfide, styrene, carbon disulfide, VOCs, hydrogen sulfide, ammonia, trimethylamine and methyl mercaptan; it can also simultaneously measure ambient temperature and humidity. The instrument is equipped with various high-precision gas sensors such as PID photoionization and electrochemical sensors, as well as a Swiss capacitive digital temperature-humidity sensor. It adopts a pump-suction sampling structure, suitable for odor gas detection and leak troubleshooting in atmospheric environments, pipelines and confined spaces, and can also detect the purity of high-concentration single gases. With stable detection performance, it adapts to various mobile monitoring scenarios.

II. Applications

Suitable for the petroleum, chemical, pharmaceutical, environmental protection and boiler industries, and can carry out pipeline flue gas analysis, air treatment, waste gas inspection, odor troubleshooting and various other odor gas detection tasks.

III. Executive Standards

IV. Product Features

1. The whole instrument is splash-proof, dust-proof, explosion-proof and shock-proof, adopting an intrinsically safe circuit design, anti-static and anti-electromagnetic interference, with a protection rating of IP66; built-in water vapor and dust filters effectively protect the sensors and the instrument body.

2. Built-in pump-suction measurement with fast response and a sampling distance of more than 10 m; the special gas path design allows detection of gases under negative pressure from -0.3 to 2 kg up to positive pressure conditions, and air pressure will not affect the test results.

3. Equipped with a 3.5-inch high-definition color screen displaying gas concentration, alarm status, time, temperature and humidity, storage, communication, printing, battery and charging status in real time; the menu uses high-definition simulated icons for intuitive and easy operation.

4. Large-capacity data storage: 100,000 data records as standard, with customization for larger capacity and optional USB flash drive or SD card expansion; supports real-time storage, timed storage and alarm-only storage modes; data can be viewed and deleted on the device, and uploaded to a computer via USB, infrared or RS232 interfaces for data analysis, storage and printing using host software.

5. Infrared, USB and RS232 interfaces are automatically recognized; optional built-in or external wireless infrared printers can print company name, gas name, date and time, ambient temperature and humidity, concentration data and test results; optional wireless transmission can synchronize data to mobile phones, remote monitoring centers, monitoring computers and other devices.

6. Equipped with a USB charging port: computers, power banks and ordinary mobile phone chargers can all supply power; features multiple protections against overcharge, over-discharge, overvoltage, short circuit and overheating, with 5-level accurate battery display and USB hot-plug support, allowing normal use of the instrument during charging.

7. Equipped with a 10000 mA large-capacity rechargeable polymer battery, offering strong endurance for long continuous operation.

8. Supports sound and light alarms, visual alarms, undervoltage alarms and fault alarms, displaying alarm status in multiple ways; alarm thresholds are customizable, with optional low alarm, high alarm, range alarm and weighted-average alarm modes.

9. Optional high-precision temperature and humidity measurement function with built-in sensor temperature compensation; the conventional operating temperature range is -40 ℃ ~ 70 ℃; with an optional high-temperature sampling cooling filter handle or high-temperature/high-humidity pretreatment system, gases at up to 1300 ℃ can be detected.

10. Wide detection range: as low as 0.001 PPM minimum and up to 99.999% Vol maximum, supporting automatic switching between high and low ranges.

11. Supports real-time and timed testing; the air pump can be turned off when no testing is required, effectively extending the device's endurance.

12. A single device can detect 1 to 6 gases simultaneously, expandable up to 18 gases; supports free switching among multiple units such as PPM, mg/m³, Vol%, LEL%, PPHM, ppb and mg/L; conventional gases require no molecular weight input, while for special gases the molecular weight can be entered for automatic conversion.

13. Provides three display modes: switchable four-gas same-screen display, single-channel large-font cyclic display and real-time curve display; channels support automatic/manual cycling, with self-selection of maximum value, minimum value and gas name, and review of historical record curves.

14. Equipped with a Chinese/English operation interface, with Chinese as the default; operation prompts are concise and easy to understand, suitable for different user groups.

15. Data recovery function: selective or full data recovery; the system automatically identifies and blocks incorrect concentration calibration operations; supports automatic zero tracking and multi-level calibration of target points, with measurement accuracy meeting national and local metrological standards.

16. Can record calibration logs, repair logs and troubleshooting solutions, with built-in reminders for sensor end-of-life and the next concentration calibration time.
