The S319 portable gas detector adopts dot matrix display technology and switches between Chinese and English interfaces, which can simultaneously detect 1-8 types of flammable and toxic harmful gases. It adopts a group type sensor element, which can be replaced with different sensor types anytime and anywhere. The detection results are displayed on the screen simultaneously.
The S319 multi gas detector is equipped with a English LCD display interface and audio and visual alarm prompts, which can adapt to concentration monitoring in more complex environments. This product is suitable for various places such as chemical, pharmaceutical, municipal, water treatment, telecommunications, archaeological laboratories, cold storage, brewing, etc.

Interface display
Numerical and curve display can be switched with one click. Default display interface, single or multi-in-one can be switched arbitrarily. Display maximum/minimum value.
Unit switching
Support free unit switching. Conventional gases are automatically switched. For special gases, molecular weight can be switched manually by inputting (ppm, mg/m3, %LEL, %VOL, ppb, ppm.mg/L, umol/mol, ml/L).
Storage log
Store alarm records, fault records, alarm concentration and time. Can record calibration logs, maintenance logs, fault solutions, sensor life expiration reminders, and next concentration calibration time reminders.
