1. Background: In response to the requirements of the environmental protection department, spot checks and testing are conducted on exhaust emissions such as SO2, NOX, CO2, CO, O2, etc. during the production process to provide data support for desulfurization, denitrification, and production processes.

2. Selected model: PTM600

3. Detection factors: sulfur dioxide SO2, nitrogen oxides NOX, carbon dioxide CO2, carbon monoxide CO, oxygen O2

4. Sensors: Electrochemical, Infrared NDIR

Explanation: Using a portable flue gas analyzer with an internal air pump, the exhaust gas in the flue is collected. After passing through a high-temperature sampling handle for dust filtration, cooling, and dehumidification, it is sent to the gas chamber for detection. The detected values are stored in the instrument for later analysis and processing.

Introduction to PTM600 Portable Smoke Analyzer

For mobile applications that require precise detection and analysis of flue gas concentration and temperature and humidity measurement, the PTM600 portable flue gas analyzer uses a 3.5-inch high-definition color screen to display concentration in real time. It adopts the best brands in the industry, including electrochemical or infrared, catalytic combustion, thermal conductivity, PID photoionization principle gas sensors, and Swiss high-precision capacitive digital temperature and humidity sensors. It can detect and analyze gas concentrations in pipelines, confined spaces, and atmospheric environments, as well as analyze flue gas. It can detect more than 500 types of gases and can also detect and analyze high concentration single gas purities of various background gases such as nitrogen or oxygen.

PTM600 portable smoke analyzer features:

Waterproof, dustproof, explosion-proof, shockproof, intrinsically safe circuit design, anti-static, anti electromagnetic interference

● Protection level IP66, built-in water vapor and dust filters to prevent sensor and instrument damage caused by water vapor and dust

Built in pump suction measurement, fast response, sampling distance greater than 10 meters, special gas path design, can directly detect gases with positive or negative pressure of -0.3 to 2 kilograms, without affecting the measurement results

The 3.5-inch high-definition color screen displays real-time information such as concentration, alarm, time, temperature, humidity, storage, communication, printing, battery level, charging status, etc. The menu interface uses high-definition simulation icons to display the function names of each menu

● Large capacity data storage function, supporting 100000 pieces of data storage capacity, and larger capacity can be customized. Optional USB or SD card storage function is available, supporting real-time storage, timed storage, or only storing alarm concentration data and time. It also supports local viewing and deletion of data. Data can be uploaded to a computer through USB, infrared communication, RS232 interface, and analyzed, stored, and printed using upper computer software.

● Automatic recognition of infrared communication interface, USB interface, RS232 interface, optional built-in or external wireless infrared printer, printing content: company name, gas name, date and time, environmental temperature and humidity, concentration data, detection results (whether qualified)

● USB charging interface, can be charged with a computer or power bank, compatible with mobile phone chargers, overcharge, overdischarge, overvoltage, short circuit, overheating protection, 5-level accurate power display, supports USB hot plugging, and the detector can work normally during charging

Adopting a 10000mA high-capacity rechargeable polymer battery, it can work continuously for a long time

● Sound and light alarm, visual alarm, undervoltage alarm, fault alarm, and multi-directional stereoscopic display of alarm status during alarm.

The alarm value can be set, and the alarm methods can be selected from low alarm, high alarm, interval alarm, and weighted average alarm

High precision temperature and humidity measurement (optional), with temperature compensation for the sensor. The instrument operates within a temperature range of -40 to 70 degrees and can detect gases up to 1300 degrees Celsius (optional high temperature sampling, cooling, and filtering handle or high temperature and high humidity pretreatment system)

It can detect 0.001PPM and can detect up to 99.999% Vol, supporting automatic switching between high and low ranges (to be specified when ordering).

It can detect in real-time or at regular intervals (for situations where the amount of gas being measured is relatively small), and the pump can be turned off to extend the start-up time when not detected.

● It can be selected to simultaneously detect 1-6 gases, up to a maximum of 18 types. The units can be freely switched. Conventional gases do not require input molecular weight, while special gases require input molecular weight to automatically calculate and switch. Units can be selected: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L

Three display modes can be switched: simultaneously displaying four gas concentrations, large font cyclic display of single channel gas concentration, real-time curve, automatic or manual cycling between channels can be switched, whether to display maximum value, minimum value, gas name can be set, and historical record curve graphs can be viewed.

The interface is selectable in both Chinese and English, with a default Chinese interface and concise Chinese or English operation prompts. Users of all ages can easily operate it

● Data recovery function, which can selectively or completely restore, automatically identifies and prevents concentration calibration errors, avoiding adverse effects caused by human factors

● Zero point automatic tracking, multi-level calibration of target points, ensuring measurement linearity and accuracy, and meeting both national standards and local metrology bureau standards.

● It can record calibration logs, maintenance logs, troubleshooting solutions, remind sensor life expiration, and remind the next concentration calibration time

Application site of portable smoke analyzer

Portable smoke analyzers are mainly used in all places that require gas concentration detection and analysis, such as petroleum, chemical, pharmaceutical, environmental protection, smoke analysis, air treatment, etc.
