2,000 to 5,000-count AVG or TRMS Digital Multimeters
MX 21 - MX 22 - MX 23 - MX 24 - MX 24B - MX 26
All-round simplicity
A rotary switch and a set of extra-wide keys give you direct access
to all the necessary functions (MIN, MAX, AVG, measurement
storage, etc.).
The labels on the keys are particularly explicit so that users can
quickly learn to use the instrument's functions intuitively.
Elegant, rugged design
In addition to their elegant design, the MX Concept multimeters
are particularly well balanced and comfortable to handle.
Furthermore, in their elastomer sheath, they can resist even the
severest operating conditions. The instrument can also be stored
safely by reversing it in the sheath, thus ensuring that the screen
and keys are fully protected.
The MX Concept models all have a large display. This allows
indication of the measurement unit and conditions (batteries too
low, AC or AC+DC measurement, autoranging, etc.).
On the MX 26, MX 24, MX 23 and MX 22, a fast segmented bar-
graph instantly indicates the measurement trend and backlighting
makes the display easy to read even in dark conditions (MX 24 and
MX 26).

Storage of measurements
All the instruments in the MX Concept
range are equipped with the MEM storage
function.
By gently pressing this key, you can lock
the display, while a second press switches
it back to normal display mode. In addi-
tion, the MX 26, MX 24 and MX 23 are
equipped with the AUTO MEM function.
This enables you, after opening the
measurement circuit, to hold the last
non-zero value measured which remained
stable for at least 1 s.
This is particularly useful when the
measurement points are difficult to
access, forcing the user to concentrate on
the test probes.
Everything is safe! First of all, automatic shutdown of the instrument after 30 minutes without use optimizes the life span of your
battery (this can be deactivated on the MX 26 and MX 24). Secondly, an automatic detection function indicates the presence of a
voltage greater than 24 V or a current greater than 10 A (MX 26, MX 24 and MX 23).
Lastly, the battery and fuses are not accessible unless the measurement leads have been disconnected.
Even greater safety
Direct display of currents
Although it does not have a current input, the MX 21 offers an original function for reading measurements in Amperes. Simply use an
MN 89 current clamp (or one of our other 100 mV/A models) and set the rotary switch to the clamp position. The instrument will then
automatically manage the transformation coefficient and display the AC current values directly in Amperes.
Measurements in µA
With its maximum resolution of 0.1 µA, the MX 22 can be used to
measure very low AC or DC currents. This is particularly useful for
applications in electronics, for example.
Dedicated functions
For simpler use, some models (MX 26, MX 24 and MX 23) offer
dedicated functions.
In this way, when the rotary switch is set to ADP, these multimeters
propose a 500 mV DC or AC+DC calibre for the use of complemen-
tary accessories: temperature sensor, tachometric sensor, current
sensor, etc.
In addition, their V low Z function (low impedance) avoids measuring
the phantom voltages which may be encountered in electrical
systems due to the stray capacitance of the cables.
Battery and fuse changes made easy!
Communication and software
Thanks to its infrared digital output, the MX 26 can be connected
directly to a computer in total safety.
Stream acquisition is performed at rates of up to 2 measurements
per second. Users can record the data, display them in graphic
form and export them, at any time, into spreadsheet software such
as Excel (SX-DMMK2 software).
It can also be coupled with up to 4 multimeters to constitute a
genuine multi-channel measurement acquisition system.
.
The SX-DMMK2 multilingual communication
kit is easy to use with the MX 26 for data
acquisition
.
The connector of the MX 26's optical digital
interface plugs directly into the instrument
without any further action required.
What could be more tiresome than looking for a screwdriver when you
need to change the batteries or fuses? The MX Concept casing is
specially designed to make this operation quick and easy, using any tool
to hand: coin, pen, steel rule, etc.
•
.
Access to the battery and fuses is particularly easy and they
can be changed in total safety, as it is impossible to open an
MX Concept casing without first disconnecting the leads.
In addition, both the battery and the fuses benefit from genuine
dedicated housings separated from the electronic circuit board.
MX 21
The excellent price/performance ratio of the MX 21 makes this 2,000-
count digital multimeter the leader among measurement instruments
designed for day-to-day electrical applications.
Its 18 mm-high digits make the display exceptionally easy to read.
It is ideal for measuring AC currents with a 200 A clamp (included with
the MX0021-T and MX0021-W versions).
MX 22
The MX 22, a 4,000-count digital multimeter, offers a particularly wide
range (400 µA to 10 A full scale) for measuring currents directly.
In addition, its fast bargraph can be used to assess variations of the
measurement or of the minimum/maximum values.
The MX Concept range
MX 23
MX 26
The MX 26 is a 5,000/50,000-count TRMS digital multimeter which is
unique in its category because it offers a bandwidth of up to 100 kHz.
With its infrared digital output, the MX 26 can be connected directly
to a computer in total safety. Users can then set up a genuine data
acquisition system with graphs, charts, alarms, etc. (SX-DMMK2
option).
MX 24 / MX 24B
As soon as it was launched on the market, the MX 24B became the
reference among 5,000/50,000-count TRMS digital multimeters.
Equipped with an ADP input, it can be hooked up to a variety of
probes and accessories: light meter, current clamp, thermometer,
tachometer, etc.
It also includes functions for low-impedance measurement (VLowZ),
current measurement directly or with clamps, a capacitance meter, a
frequency meter and a MIN/MAX/AVG monitoring mode.
The MX 23 is a highly accurate 5,000/50,000-count TRMS digital
multimeter with reinforced safety features. It gives the true root-mean-
square value whatever the waveform of the signal, whether sinusoidal
or distorted, with or without a DC component. Range selection is
automatic by default and helps to prevent handling errors.
This multimeter includes an ADP input for current measurement with
clamps (see selection tables).
This fuseless model is particularly effective and economical.
