Chauvin Arnoux DigiFlex Current Tester MA400D P01120575Z

TRMS Digital ammeters with flexible sensor

DigiFlex Comes Supplied With:

  • 1 DigiFLEX sensor
  • 2 x 1.5V AAA batteries
  • 1 elastic strap
  • Operating manual in 5 languages

MA400D and MA4000D DigiFLEX current testers are equipped with flexible current sensors connected to a compact casing and can be used comfortably in any electrical cabinet for applications up to 600 V CAT IV.
These stand-alone instruments are equipped with a 4,000-count digital display for direct current readings.
Simple to set up thanks to the sensor-closing system, DigiFLEX current testers also benefit from the magnetized Multifix mounting system allowing them to be positioned anywhere.

An ideal addition to the electrician’s kit of tools and measuring instruments, the DigiFlex can be used for TRMS AC current measurements while also providing a solution when access to the electrical conductors is difficult. The range comprises 2 models: the MA400D version, whose measurement range starts at 20 mA, is designed for work in residential conditions and can also be used to check electricity distribution points up to 400 A.

The MA4000D version can be used on higher-power installations in industry and the energy production sector. Although it is a high-performance instrument, the DigiFlex remains very simple to use: 2 buttons are all it takes to start the instrument, deactivate the automatic power-off function, HOLD the value on the display or store the maximum value (MAX HOLD). The values are read directly on the built-in 4,000-count display. It is also particularly practical, as the shape of the casing is designed for comfortable handling, the articulated, magnetic MultiFix system makes it simple to position and the velcro strap facilitates storage.

Delivery Notices (Updated March 29th 2021)

During the current situation surrounding the effects of the Coronavirus pandemic, logistics from every company are under immense pressure to deliver goods on time.
Coupled with manufacturers on reduced output due to more stringent working practices and a global shortage of component parts to supply UK manufacturing, we have taken the decision to 
temporarily limit our services rather than let our customers down amid these unprecedented circumstances.
We hope you will understand our position on this and we apologize unreservedly for the inconvenience we know it will cause.

Please note that ALL orders placed before 3:00pm are shipped same-day (subject to stock and any additional services required).
The stated transport times above have some scope for adjustment built-in for the Covid-19 situation. Carriers themselves also have their own extended workload and limitations at this time which are unfortunately beyond our control.

Orders requiring calibration 

Whilst we take the greatest care to get all orders dispatched and delivered to you in the stated time frame, orders received PM and requiring
calibration may on occasion miss dispatch that day, according to the complexity of the calibration. Be assured they will ship on the next dispatch
this in most cases should not add more than 24 hours to your delivery.

Bank/Public Holidays

Predicted delivery times are based on regular trading days Monday to Friday. Public holidays, bank holidays and weekends are outside the usual scope
of our dispatch and subject to activities/holidays of our carriers and therefore may incur additional days lead time to your order.
