Automatic calibration
Troublesome calibration procedures have been reduced to the push of a function key. At the Auto-Interval Calibration (AIC) menu you can set the start time, the start range, and the interval for the automatic calibration. The system clock and calendar then assure that your calibration instructions are executed precisely. To make things even easier, remote auto-calibration can also be done from your own computer, via the monitor's RS-232C serial port (optional).
Auto-range function
An auto-range function that automatically switches to the range best suited to the object gas concentration for both momentary and average values is included as a standard feature. As an option, even when randomly set to any range (within 10 times the range ratio), the auto-range function can still be used. Switching over from auto-range to manual-range is a simple task.
Selective data output
For each component measured, the system provides four types of data: momentary values, integrated values, moving averages, and simple averages. Any two these data may be output. Simultaneously to any two external devices (e.g., PC, printer). The time-span for both average and integrated values may be specified (i.e.,when the momentary value has not been selected). With the simple average values, three different timesettings can be specified.
Storing data in memory
Four different values may be stored in memory: three simple averages and the
integrated value.
For example:
Average value #1 (3 min) → 1,000 data sets
Average value #2 (30 min) → 1,000 data sets
Average value #3 (3 h) → 100 data sets
Integrated value (1 h) → 1,000 data sets
Network Communications (option)
Serial communication is available through RS-232C serial port connected on the rear panel. The serial port makes analyzer data available using HORIBA's proprietary serial communication protocol, and can be easily converted to RS-485 for network data collection. Ethernet communication is available through an optional port using TCP/IP protocol. Modbus(R) is also available as a serial protocol option.
Memory card for data management (option)
An available Compact Flash(CF) can save average or integrated value, and read and collect data for off-line analysis.
With the CF it is possible to conveniently use the analyzer in a stand-alone mode.
Readout toggles to mg/m3, µg/m3
A touch of a button on the front panel is all that is needed to toggle the readout
from ppm or ppb to mg/m3.
(Not available on Model APHA-360, where CH4 values
are displayed as ppm, NMHC and THC as ppmC.)
Pressure-compensation
Automatic compensation for ambient pressure assures reliable data regardless of the weather or the monitor's location.
Easy-to-read, 326x240 dot LCD
display with touch panel screen.
The adoption of full graphic LCD for the touch screen offers a large, easy-to-use display and user friendly, interactive operation. This user interface facilitates maintenance with displays such as the graph of intensity, remaining time before replacement of pumps, valves, source lamp and converters. It also allows you to save average value, data, integrated value alarm history and calibration history.
Minimal influence from interference
components and ambient temperature
These monitors use HORIBA's innovative detection techno-logy and sampling method for outstanding sensitivity. The influence from interference components is minimal and results are very stable over long periods of measurement.
Input/output via RS-232C port (option)
The system's RS-232C serial port can be used to transmit measured values, alarms, and other data to remote equip-ment. It can also be used to input changes to parameter settings and other data. A hard-copy printout of measured values can be produced by attaching a recorder to the RS-232C port.
At last—a small, compact system
A small, light-weight unit for each component to be mea-sured fits neatly into a 19inch rack. This makes it easy to up-grade your system in the future. This new design offers great savings in valuable lab space.
