JK40-O2-Wmulti-functionaltraceThe oxygen detection alarm is used for portable and rapid detection of various gas concentrations, temperature and humidity measurements, and alarm for exceeding the standard. The JK40-O2 multifunctional oxygen detection alarm adopts a 2.4-inch high-definition color screen to display concentration in real time, and uses well-known brand gas sensors. The main detection principles include electrochemistry, infrared, catalytic combustion, thermal conductivity, and PID photoionization. Advanced circuit design and mature kernel algorithm processing have obtained multiple software copyright patents and appearance patents. JK40-O2 can detect in pipelines, confined spaces, and atmospheric environmentsTrace oxygenConcentration can detect gas leaks or high concentrations of various background gases such as nitrogen or oxygenSingle gasPurity, detecting gas types exceeding500Seed.

JK40-O2-Wmulti-functionaltraceCharacteristics of oxygen detection alarm:

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.

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 Celsius,

Can detect gases up to 400 degrees Celsius, and can be customized for higher temperature gas detection (optional high temperature sampling, cooling, and filtering handle or high temperature and high humidity pretreatment system)

Can simultaneously detect 1-4 types of gases, with freely switchable units. Conventional gases do not require input of molecular weight, while special gases require input of molecular weight and automatically

Calculate and switch, units available: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L

Three display modes can be switched: simultaneous display of four gas concentrations, large font cyclic display of single channel gas concentration, real-time curve, and each channel

The automatic or manual cycle can be switched between, and whether to display it can be setMAXValueMINThe small value and gas name can be viewed in the historical record curve chart.

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.

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