Demo Multimeter DM45
Model : 32450
* 4 digit “4000” large 57 mm LED display
with 2 character
unit display
* 5 measuring functions: V, A, Ohm, °C
(or °F)/K and pH
* 4 push-buttons for easy use
* Rear display for the teacher
* Works also as remote display for e.g.
balance
* Galvanic separated RS232 interface
Multimeter for demonstration with extra
display and RS232 interface on rear side.
Use it as Voltmeter, Ammeter,
Ohmmeter, Temperature Meter and
pH Meter in your class demonstrations, or as avery large display for your Scale/Balance.
Demo Multimeter / Remote Display Type DM45 is by the versatile measuring possibilities particularly suitable as
measuring instrument in education and in the laboratory.
The device is microprocessor controlled and supplied with RS232 interface cable for PC and Windows program.
The instrument can be used as a stand-alone instrument or connected to a PC or other measuring instrument.
With the PC connected, all functions can be controlled and recorded. When connected to e.g. an electronic
balance, the instrument acts as a remote display. For optimum performance and trouble-free connection, the
interface is galvanically separated from any other parts of the instrument.
For the teacher’s convenience a display (4 digit 21 mm LED) is placed at the rear panel of the instrument.
Measuring modes:
Multimeter: Voltage ac and dc, current ac and dc,
resistance in Ohm and kOhm.
Temperature meter: Thermocouple NiCr-Ni (type K) input
for measurements in a wide range from -40°C to +1200°C
with display of temperature in °C or °K.
pH meter: BNC-input for pH-combination electrode in the
range 0.00 to 14.00 pH. Temperature compensation is
automatic (from temperature-meter input or from ambient
temperature) or can be set manually from 0 to 50 °C. Both
the buffer and the sensitivity (Nernst equation) is
adjustable from the front-panel or through the PC
interface.
Dimensions: (WxHxD) 310x220x230 mm
Weight: 5.9 kg
