Analyzer Type |
|
H2 Analyzer
|
|
| |
|
For continuous analysis of hydrogen (H2) with active carbon dioxide (CO2) compensation. Recommended for continuous analysis of exothermic (DX) atmosphere gases from a generator or a furnace, and other process gases.
| |
|
- High accuracy - continuous CO2 compensation of H2 reading
- Bright digital readout, and voltage or 4 - 20 mA outputs
- Long life thermal conductivity (TC) detector with high accuracy and repeatability, cannot be burned out from loss of flow
- Separate NDIR CO2 detector
- Easy-to-maintain modular layout
- Built in sample pump, filters, and flowmeter
| |
|
- Hi/Low H2, CO2, low flow, and diagnostic alarms available
- Isolated analog, RS232, RS485, MODBUS, and Ethernet outputs available
- Sample conditioning systems available for removal of moisture, acidic gas, and dust
- Cabinet purge system available for use in hazardous areas
- One-step 'cal-now' button with touch screen LCD display
- Full automatic calibration with touch screen LCD display
- Cabinet coolers can be fitted to most models
- Sensors mounted in temperature controlled heated box to improve accuracy
- High temperature filters and probes
| |
|
- On nitrogen or air for zero
- On a blend of 80-90% of full scale range of H2 & CO2 for span
