Technical Data
149
pH MEASUREMENT
Measuring rate:
1 measurement/s with single and also with double measurement
Measuring range:
0.00 pH bis 14.00 pH
Accuracy:
±0.01 pH ±1 digit in ambient temperature 0°C to 50°C
Resolution:
0.01 pH
Slope range:
-62 mV/pH <= S <= -50 mV/pH
Asymmetry potential:
-45 mV <= Uasy <= +45 mV
SensorCheck:
Electrode control, alarm signal wird is lead via SensCheck-
relay (not in connection with ADA/pH 171).
AVERAGING
Daily MIN and daily MAX values are computed out of mean
values determined over 1/5/15 min periods. The last valid daily
minimum and daily maximum value are stored together with the
time when they occurred. They are stored in the EEPROM. The
daily MIN and MAX values can be called up in the display.
pH CALIBRATION
Procedures:
AUTOCAL TEC with technical buffers (2.00, 4.01, 7.00, 10.00)
CONCAL
with any buffers (one point or
two point calibration)
REDOX POTENTIAL MEASUREMENT
Measuring rate:
1 measurement/s with single and also with double measurement
Measuring range:
-1000 mV .. +1000 mV
Accuracy:
±2 mV ±1 digit in ambient temperaure range 0°C to 50°C
Resolution:
1 mV
TEMPERATURE MEASUREMENT
Measuring rate:
1 measurement/s
Measuring range:
0.0°C ... 50.0°C
Accuracy:
± 0,2 K ±1 digit
Resolution:
0.1 K
Additional fine adjustment by ± 0.5 K designed in the software in order to avoid display
discrepancies when changing the electrode.
