Seaward Apollo 400 Review

Seaward introduced the Apollo 400 as a “straightforward, no-nonsense” PAT tester. It sits in the Apollo range as a practical, mid-volume tester with a strong focus on usability and record keeping. This review focuses on what the Apollo 400 does well, what’s been removed compared with higher models, and the sort of user it suits.

How does it compare to the Apollo 500?

The Apollo 400 is based around similar hardware and performs the same core electrical tests as the Apollo 500, but with firmware changes that reduce memory capacity and remove some additional features. In practice, the reduced memory isn’t usually a major issue if you download records regularly, and the remaining test sequences are sufficient for most users.

Some convenience features are also removed (for example, importing prior records for re-testing, password accounts and certain built-in calculators). For many electrical contractors this won’t matter, but for in-house teams it can be a “nice to have”.

Using the Apollo 400

The instrument is compact, lightweight and well built. The colour screen and menu system are intuitive, and the QWERTY keyboard is the standout feature — it makes entering locations, asset IDs and descriptions much faster than scroll-and-select interfaces.

There are two main test options: predefined test sequences, or single test mode. Most users will primarily use the test sequences day-to-day.

Software options

Seaward PAT testers are commonly used with Seaward’s PATGuard software for managing test records and producing reports. The Apollo 400 can also export records for use with third-party software, depending on your workflow.

Tip: when choosing software, think about how you’ll handle retests, customer reports, certificates, asset labels and backups, this is often more important than a small difference in tester price.

Specifications and test capability

Like other Apollo models, the Apollo 400 can operate on battery power or from the mains. When connected to the mains supply, it can perform full mains-powered tests such as load and leakage. When operating on battery power, sub-leakage testing can be used as an alternative.

The insulation test can be set to 500V or 250V (useful where surge protection or sensitive equipment requires reduced voltage testing). The earth continuity test is carried out at low current (typical of battery PAT testers), which is generally acceptable, but can be more affected by contact resistance than high current bond testing.

The Apollo 400 also includes an RCD test facility, as recommended by the IET Code of Practice.

Verdict

Overall, the Apollo 400 is a fast, practical tester that’s easy to use and particularly strong on data entry thanks to the QWERTY keyboard. It’s a solid option for users who need reliable record keeping without paying for features they won’t use.
