Portable acetaldehyde detection alarm device

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

IP65 protection level, 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 be directly detected

Gas with negative or positive pressure ranging from 0.5 to 2 kilograms has no effect on the measurement results

The 2.4-inch high-definition color screen displays real-time concentration, alarm, time, temperature, humidity, storage, communication, and power

Charging status and other information, the menu interface uses high-definition simulation icons to display the function names of each menu

● Large capacity data storage function, with a standard storage capacity of 100000 pieces of data, and larger capacity can be customized. Support real-time

Storage, scheduled storage, or only storing alarm concentration data and time, supporting local viewing and data deletion,

Data can also be uploaded to a computer through a USB interface, and analyzed, stored, and printed using upper computer software.

● USB charging interface, can be charged with a computer or power bank, compatible with mobile phone chargers, overcharge, overdischarge, overvoltage, etc

Short circuit and overheating protection, 5-level accurate power display, supports USB hot plugging, the detector can work normally during charging, and RS485 communication is optional

Adopting 4500mA high-capacity rechargeable polymer battery, it can work continuously for a long time

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

Can detect gases at temperatures ranging from -40 ℃ to+70 ℃, and can be customized for higher temperature gas detection (optional high temperature sampling and cooling filter handle or high temperature and high humidity pretreatment system)

● Gas units can be freely switched for detection, with optional units: PPM、mg/m3、Vol%、LEL%、PPHM、ppb、mg/L

● Display mode: display gas concentration, large font cyclic display of single channel gas concentration, real-time curve,

You can set whether to display the maximum value, minimum value, and gas name, and view the historical curve graph.

The interface is selectable in both Chinese and English, with a default Chinese interface and concise Chinese or English operation prompts

● Data recovery function, which can selectively restore or fully restore, eliminating the worries caused by misoperation

● Zero point automatic tracking, long-term use is not affected by zero drift.

Three level calibration of the target point ensures the linearity and accuracy of the measurement, and can simultaneously comply with national standards and local metrology bureau standards.

Automatic identification and prevention of concentration calibration errors can avoid adverse effects caused by human factors.

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.
