A - BASE MODEL
- Easy to use manual potentiometer calibration with LCD digital displays for each gas
- Temperature controlled sensors for maximum stability
- Long life electrochemical O2 sensor
- Infrared detector for reliable measurement of CO2 and CH4 (Models other than 910A or 910C). Detector may be cleaned in the field
- Stainless steel hard tubing and corrosion-resistant components for internal sample health
- Cabinet positive-pressure system to minimize the corrosive effects of hydrogen sulfide (H2S) on cabinet electronics & sensors
- Built in sample pump, pre-filter, filters, and flow meter
- Automatic moisture removal without the use of cooling water, compressed air or failure-prone thermal-electric elements
- Back pressure regulator to allow user to measure and minimize vacuum effects if the unit is vented back to the blower
- Rugged NEMA4 (IP65) enclosure
- Isolated 4 - 20 mA outputs for each gas
- Low flow alarm & relays
C - AUTOCALIBRATION MODEL
- Same features as Base model, plus:
- Automatic analyzer calibration with full-color touch screen LCD display
- Diagnostic alarms with troubleshooting guidance in display
- 'Cal Now' feature initiates full calibration with a single swipe of a magnetic wand
| |
|
- H2S & BTU readouts (see ranges and models)
- Gas hi/low alarms with relay contacts
- RS232, RS485, MODBUS® and Ethernet outputs (available on Model C only)
- Class 1 Division 2 Group BCD rated purge kit for use in hazardous areas
- Outdoor weather package for operation from -22°F to 158°F (-30°C to 70°C)
- O2 measurement by paramagnetic detector
| |
|
- Ambient air for O2 span and CO2 & CH4 zero
