The EC 25 is used wherever an EX-proof unit with high selectivity is needed. A LCD display shows the actual gas concentration. Calibration can be exercised with a little handling on-site. A rugged stainless steel casing protects the electronic. The EC 25 EX is designed in protection class IP 54, which protects the unit against splashing water. It can be operated as a stand-alone unit or in combination with any GfG controller.
