Dimensions & Weight Standard sensor: Standard sensor weight: Electrical & Interfaces Platform Alarm indicators: 2 user programmable, 1 system fault, Form C relays Power requirements: Power consumption: Signal output: User interfaces: Data storage: 5.7” LCD touchscreen. 10/100 Base-T Ethernet. USB, RS-232, RS-485. Modbus TCP (optional) Internal or external flash drive H2 supply (maximum 10 ppm H2O and O2 impurity) is required for sample conditioning via catalytic conversion. For enhanced safety, a special model is available which uses a mixture of 3% H2/97% N2 as an alternative to pure H2. See...

Standard Model (using pure H2 utility gas) CO2 Model (using pure H2 utility gas) Enhanced Safety Model (using 3% H2/97% N2 mixture utility gas) Contact us for additional analytes and matrices or information about our optional purged enclosure. † LDL is dependent upon the quality of the sample gas and the integrity of the sampling system. ‡ LDL is limited by minimum achievable O2 concentration, not by 3σ baseline noise. § LDL of 1000 ppt requires addition Gas Panel and Linear Fit Mode. Please contact us for more information. U.S.

Optional Packages Customize your HALO OK analyzer with these powerful add-ons: Zero Gas Panel • nserting a purifier into the Test Path allows for I verification of the analyzer’s Zero Calibration • elps achieve lower detection limit in CO2 in H combination with Linear Fit Mode • pool pieces are included to allow insertion S of purifiers with different lengths Linear Fit Mode • inear y = a x + b fit function permits user-defined L calibration curves with programmable slope (a) and offset (b) • utomatically adjusts readings to factor in A dilution probes and sampling system offsets, while retaining...
