Hach, 3660EX/218.B, Orbisphere 3660EX ATEX Controller for Hydrogen (H₂) measurement, wall mount, 230V AC, units : %

Intrinsically Safe Analyzer
The 366xEx family of instruments measures oxygen (O₂), hydrogen (H₂), and ozone (O₃) in areas where hazardous and flammable condi¬tions are possible. When coupled with a choice of membrane covered, electrochemical sensors, the 366xEx is suitable for sampling dissolved concentrations from trace ppb to supersaturation, and gaseous con-centrations from ppb to percent (%) levels. These sensors can be constructed from a variety of chemically resistant materials and use an assortment of membranes with permeability and chemical resistance to optimize long-term measurement performance.
ATEX certified
3660 supports European Community regulation, with ATEX directive and standards with marking: Ex II (1)1G, Ex [iaGa]ia IIC T6 Ga (corresponds to NFPA Class l Div l Group A,B) and IEC Certification IECEx LCI 09.0027x
Consistent and accurate measurements
Used to measure in aqueous or non-aqueous samples such as organics, olefins, fuels, monomers, aromatics, specialty chemicals, water, and other liquids and gases.
Easy installation
Easy installation and sampling with in-line and sidestream accessories.
Easy calibration
Flexible and verifiable calibration in air, liquid, or gas standard with negligible drift.
