The ChemLogic® Revive™ CL4R is a technologically-advanced colorimetric fixed gas detector. The system is designed to directly upgrade and replace a four-point legacy monitor, with the ability to also retrofit into a legacy rack system (see specifications). It integrates seamlessly using existing externals, with no required modifications. The CL4R is ideal for use in semiconductor and other commercial/industrial environments requiring low-level gas detection. The CL4R provides an invaluable life safety service to workers, while helping keep inventory production operational.
