666 221
Hand-held pH meter
For measuring pH, temperature and redox
values. If a temperature sensor (666 241) is
connected, temperature compensations are
carried out automatically; otherwise the temperature
is entered manually on the keypad.
Measurement ranges:
pH: 0 ... 14 pH ±0.05 pH
–1999 ... +1999 mV ±5%
Temperature:
–199.9 ... +199.9 ˚C ±0.5 ˚C (Pt 1000)
–10.0 ... +110.0 ˚C ±0.2 ˚C (NTC)
Input resistance: 10 19 ohm
Inputs: pH DIN socket (DIN 19 262)
DIN socket, 8 pins (for temperature sensor)
Output: DIN socket, 8 pins, serial (RS 232)
Power supply: 9 V battery
667 417
pH single-rod electrode
In unbreakable plastic shaft suitable for outdoor
use, with DIN plug, 13 mm dia.
666 241
Temperature sensor Pt 1000
For temperature measurement and automatic
temperature compensation.
667 415
Redox probe
For oxidation-reduction measurements, with
platinum pin and Ag/AgCl reference system;
with DIN connector, 13 mm dia.
666 222
Hand-held conductivity meter
For measuring the conductivity (conductance)
of solutions. Temperatures are compensated
automatically by the temperature sensor (integrated
in the conductivity measurement cell) or
manually by entering the values. This device
can also be used to measure temperatures.
The conductivity measurement cell is calibrated
by entering the cell constant or with the help of
the calibration solution. The measurement
range can be selected manually or automatically.
Measurement ranges:
Conductivity:
0 ... 19.9 µS ±1%
0 ... 1.999 mS ±1%
0 ... 19.9 mS ±1%
0 ... 199.9 mS ±2%
Temperature:
–10.0 ... +110.0 ˚C ±0.2˚C (NTC)
–199.9 ... +199.9 ˚C ±0.5 ˚C (PT 1000)
Input: DIN socket, 8 pins
Output: DIN socket, 8 pins, serial (RS 232)
Power supply: 9 V battery
666 242
Conductivity measurement cell
With integrated temperature sensor for automatic
temperature compensation
666 224
Hand-held oxygen meter
ecology
This device is used for measuring the absolute
content of oxygen in solutions and the relative
saturation of oxygen. The displayed concentration
of oxygen is corrected automatically for air
pressure and temperature, which can also be
displayed.
Measurement ranges:
0 ... 19.99 mg/l oxygen concentration in
aqueous solutions
0 ... 199.9 % relative saturation in
liquids or air
Temperature: 0 ... 45 ˚C ± 0.5 ˚C
Air pressure: 800 ... 1100 hPa ±10 hPa
Input: DIN socket, 8 pins
Output: DIN socket, 8 pins, serial (RS 232)
Power supply: 9 V battery
667 458
Oxygen electrode
For measuring concentrations of oxygen and
the relative saturation of oxygen. Complete with
an integrated temperature sensor for automatic
temperature compensation, zero-point and
electrolyte solutions for calibrating the
electrode.
667 451
Accessory set for the oxygen electrode
Contains 5 spare caps with membranes.
