Calibrators

A process multimeter is an indispensable tool for the electrician or technician working with control and instrumentation, as it combines the common measurement functions of a multimeter with the process calibrator's capabilities to simulate signals and act as a source in passive circuits.

Elma 6620 is a simple process multimeter in a robust and ergonomic design with a backlit display and built-in flashlight.

The measurement functions include true RMS AC voltage and AC voltage with VFC filter for precise measurement on noisy circuits and circuits with variable voltage, DC voltage, resistance/continuity, diode test, frequency, and AC/DC current in mA.

Elma 6620 can simulate signals in both active and passive circuits. In both cases, the 4-20 mA output signal can be set in steps of 25%, and the current can be fine-tuned down to 0.001 mA; the step and ramp functions allow for automatic stepwise or smooth adjustment of the output current. With Elma 6620 as the source, passive circuits can also be subjected to 1-10 VDC or a frequency signal. Elma 6620 also has a Loop power function.

Elma 6620 is delivered ready to use including test leads with test probes, mini alligator clips, batteries, and a manual.

Elma MS4202 is a small, handheld calibrator, both simulating active and passive on top of measuring current and voltage.

The instrument will stepless provide 0…22mA or 0…10V DC and furthermore provides lockable 4/20mA and 2/10V.

Elma MS4202 measures 0…22mA and 0…25V DC. All values are displayed on the LCD and sockets are for standard 4mm banana plugs.

Elma MS4202 is ideal for e.g. the service technician and for balancing HVAC and other automated systems using analogue signals. The instrument is battery powered, making the user independent of external power supplies, although it’s possible to connect external supply for long term use. The instrument is provided ready to use in a bag incl. battery and test leads.

Elma 326 is a small and durable sound calibrator, offering two sound levels for testing and verification of sound measurement equipment. The instrument fulfils 60942 class 2 and is provided ready to use in a bag including batteries and manual. The calibrator is suitable for 1” and 1/2” microphones.

A process multimeter is an indispensable tool for the industrial electrician or technician working with control and instrumentation, as it combines the common measurement functions of a multimeter with the process calibrator's capabilities to simulate signals and act as a source in passive circuits.

Elma 6660 is an advanced process multimeter in a robust and ergonomic design with a wealth of features, high accuracy, a backlit display, and a built-in flashlight.

The measurement functions include TRMS AC voltage and AC voltage with VFC filter for precise measurement on noisy circuits and circuits with variable voltage, DC voltage, resistance/continuity, diode test, capacitance, frequency, AC/DC current in mA, and temperature with thermocouple (e.g., type K) and RTD (e.g., PT100).

Elma 6660 can simulate signals in both active and passive circuits. In both cases, the 4-20 mA output signal can be set in increments of 25% and the current can be fine-tuned down to 0.001 mA; the step and ramp functions allow for automatic stepwise or smooth regulation of the output current. Passive circuits can be supplied 1-10 VDC, a frequency signal, resistance value, and thermocouple as well as RTD temperature signal with Elma 6660 as the source. Elma 6660 also has Loop power and 250 Ω HART function.

Elma 6660 is delivered ready to use in a pouch, including test leads with test probes, mini alligator clips, batteries, and manual.
