Description

Chauvin Arnoux CA6424 Earth Tester

Product Details:

The Chauvin Arnoux CA6424 Earth Tester is the ideal instrument for 2P and 3P earth measurements to be taken safely and easily. Both text markings and colour coding help the users to avoid connection errors. Users are able to measure voltage up to 600V with all measurements and functionality are directly accessible on the front panel which can be used even with gloves on.

With automatic start up in 2P earth measurement mode, the CA6424 instantly allows the user to test the integrity of the H stake. When using the 3P earth mode, the CA6424 memorises the 52%, 62% and 72% measurement values and calculates the differences in % relation to the average. If the difference is too large , the percentage value is displayed on screen with a flashing display.

Users are able to use the CA6424 to measure line (phase) current and leakage current from 0.5mA to 60A thanks to the special connection technology for the G72 clamp (optional). The CA6424 has a dedicated key for cable compensation, whilst the LED screen indicates when a hazardous voltage is detected, with a NOISE symbol flashing should noise voltage be present. If a noise filled environment is detected, the CA6424 automatic switching from a frequency of 128Hz to 256Hz will help improve the measurement accuracy.

The CA6424 boasts a 3 display backlit screen with users able to view useful measurements on a single screen, any errors detected in measurements or recorded values as well as complementary information such as USE and HR.

The CA6424 complies with IEC 61557-1 and IEC 61557-4 and is 600V CAT IV rated. The unit is IP65 rated offing protection from dust and low pressure water jets from any direction and has been drop tested to 1 metre as per IEC 61010-1 .Powered by 6 rechargeable batteries, the CA6424 has a battery life for up to 1500 measurements 3P earth measurements at 10Ω with an automatic power off function that can be deactivated further preserving battery life.

🚚 Testersmans Shipping Policy

Free Mainland GB Delivery Over £150

We offer free delivery on most mainland Great Britain orders over £150 (ex VAT).
This applies across England, Wales, and most of Scotland, excluding certain remote or offshore postcodes.

If your order total falls just short of £150, or you’re a returning customer, feel free to contact us — we may be able to offer a discount code or delivery workaround.

📦 UK Delivery Options

We work with both Royal Mail and DHL to offer reliable and flexible delivery across the UK:

  • Royal Mail – Best suited for lighter parcels and for customers in remote regions, including the Highlands, Islands, and Northern Ireland.
  • DHL – Ideal for most mainland UK orders, providing fast, tracked delivery and excellent reliability for time-sensitive shipments.

Our checkout system automatically displays the available delivery services for your postcode and order weight, ensuring you always see the most suitable options.

Note: Heavy, bulky, or freight-only orders will be charged separately.
Our website is designed for quick, transactional purchases rather than bulk or palletised orders.
Please contact us in advance for a tailored freight quotation if your order falls into this category.


⏱ Dispatch & Delivery Timing

We aim to dispatch all in-stock orders promptly, but delivery depends on both when you order and which service you select.

  • UK orders: placed by 2:00 PM Monday–Friday are usually dispatched the same day.
  • International orders: placed by 2:00 PM Monday–Thursday are usually dispatched the same day.

Orders placed after these times are processed the next working day. This means delivery may occur the following day or later, depending on the courier and service selected.

Once dispatched, your chosen delivery service determines how quickly your parcel arrives:

  • Standard services We use Royal Mail Tracked 24 or DHL Parcel as our ‘Standard’ services. They are not guaranteed to arrive next working day.
  • Premium services (e.g. Royal Mail Special Delivery or DHL by Noon) offer guaranteed delivery windows.

If your order is time-sensitive, we strongly recommend choosing a guaranteed service or contacting us before ordering to confirm availability.

Please note: For logistical reasons, we may occasionally adjust the delivery method selected at checkout. For example, smaller items may be better suited to letterbox-friendly packaging or may be at greater risk of delay or loss via certain services. We actively monitor courier and postal service disruptions—including strikes and delays—and may modify shipping arrangements to help ensure timely and secure delivery.


📅 Busy Periods & Delays

We always aim to dispatch promptly, but delivery times may be affected by:

  • Seasonal demand (e.g. Christmas, bank holidays, or industry shutdowns)
  • Courier network delays outside our control
  • Supplier lead times or calibration requirements for certain equipment

If your delivery is time-critical, please contact us before ordering so we can confirm stock and courier availability.


🌍 International Shipping

We ship worldwide using UPS Express Saver® and other trusted global courier partners. All international shipments are tracked and generally dispatched Monday to Thursday to ensure smooth customs clearance and transit.

Estimated delivery times:

  • Europe: 1–2 working days
  • North America: 2–3 working days
  • Asia-Pacific & Rest of World: 3–5 working days

Delivery times vary depending on location, customs clearance, and local courier performance.


💰 Taxes, Customs & Import Duties

International customers are responsible for any applicable taxes, customs charges, or import duties.
These are not included in our product or shipping prices.

Your courier will typically provide a secure payment link for any import charges once your parcel reaches customs.
If import fees are refused and the parcel is returned, we will issue a refund minus all incurred shipping and return costs.
