Description

Zhong'an S400 is an intelligent multi-functional gas detection instrument. (Different gases can be combined in a four-in-one or five-in-one combination). The instrument is manufactured by using high-performance detection components, computer micro-control technology, and combining with advanced fully automatic surface mounting technology. The product has functions such as on-site buzzer indication sound, on-site flashing indicator light, etc., and displays the on-site gas concentration in real time for monitoring.
