Is there a portable gas detection device that can detect four gases?

I don't know if it is the kind you need.

1、? technical characteristics

SF6 comprehensive tester is a collection of SF6 micro-water meter, SF6 purity meter and SF6 decomposition product analyzer, which integrates the functions originally realized by three instruments into one instrument. One field measurement can detect three indicators, which greatly saves the gas in the equipment, and one measurement can save 2/3 of the gas consumption, reducing the workload of users and improving the work efficiency.

? Quick gas saving: After starting up and entering the measurement state, the dew point measurement time of each SF6 gas barrier is about 5 minutes. The measurement time of SF6 purity and SF6 decomposition is about 2 minutes.

? Self-locking joint: Self-locking joint imported from Germany is adopted, which is safe and reliable without air leakage.

? Data storage: large-capacity design, which can store up to 200 sets of test data.

? Curve function: large screen curve shows dew point measurement process.

? Clear display: LCD screen directly displays dew point, micro water (ppm), SF6 purity, SO2, H2S, CO and HF content, ambient temperature, ambient humidity, time and date, etc.

? Built-in power supply: built-in 4Ah rechargeable lithium battery can work continuously 10 hour.
