The MA2390-8 has a 512 KB EEPROM for logging 64,000 to 100,000 measured values and may be connected to virtually any sensor. It features RS232 and analog (mV) outputs for recording measured data. When connected directly to a computer, multiple ALMEMO instruments may be networked together and interrogated per user-assigned instrument addresses. The MA2390-8 features three separate input channels and a fourth, virtual channel, on which the difference between the first two channels may be viewed (and output via RS232 or analog).
-Temp. measurement with automatic differential
channel
-Chemical variables : pH, redox, conductivity,
solute oxygen (with simple sensor adjustment) etc.
-Mechanical variables : force, displacement (with zero-point and setpoint
adjustment)
-Ventilation measurement with volume flow, network meas., measured value
smoothing, averaging over single measurements or continuously with number
of values diameter, cross-section, Pitot tube measurement, compensated
for temperature and atmospheric pressure
-Wet-bulb globe temperature (WBGT) measurement
-Structural meas. operat. with calculation of thermal coefficient
- 5 ALMEMO® input sockets, electrically isolated, for 5 ALMEMO®
sensors
- More than 65 standard measuring ranges
- Easy-to-read 8Ω-character 12-mm LCD
- Measuring functions : Measured value, zero-setting,maximum and minimum
values, average value, double display for temperature and humidity,
temperature compensation and atmospheric pressure compensation
- Sensor programming Measuring range, correction of measured values, scaling,
units, limit value monitoring, graduated locking of functions, scaling of analog
output
- Device programming: Real-time clock with date and time-of day, cycle for
measured value output, output formats for printer and spreadsheet software,
baud rate, selection of language for function abbreviations
