Seaward PrimeTest 100 PAT Tester (Portable Appliance Tester)
- Simple, reliable and fully 5th Edition compliant
The Seaward PrimeTest 100 is a trusted, easy-to-use portable appliance tester designed for reliable safety checks on electrical equipment. Ideal for those with low to medium volume testing needs, this compact and battery-powered Seaward PAT Tester 100 makes electrical safety straightforward—whether you‘re working in schools, care homes, workshops, or the leisure sector.
Now updated to comply with the 5th Edition IET Code of Practice, the Seaward PrimeTest 100 PAT tester includes a brand-new 250V insulation resistance test. This new feature allows you to test surge-protected and sensitive electronic devices without risk of damage, all while maintaining safety compliance.
Why Choose the Seaward PrimeTest 100 PAT Tester?
The Seaward PrimeTest 100 stands out as one of the most beginner-friendly testers available. Designed for users who need a fuss-free experience, it offers a simple three-button operation with clear PASS / FAIL indicators displayed on a large LCD screen. It‘s perfect for anyone looking to carry out portable appliance testing without needing advanced training or complex equipment.
Whether you‘re testing Class 1 appliances, Class 2 (double-insulated) items, extension leads or IT equipment, the Seaward PAT Tester 100 delivers accurate results with minimal effort. It even detects whether an appliance or an extension cord is connected, thanks to its internal smart circuit.
Seaward‘s ZAP Technology – Accurate Results Every Time
Unlike many other basic PAT testers, the Seaward PrimeTest 100 PAT tester includes Seaward‘s innovative ‘ZAP‘ technology. This system ensures that earth continuity measurements remain accurate even under difficult conditions, such as testing through rust, paint, limescale, or other contaminants.
Earth continuity testing is one of the core components of portable appliance testing, and ZAP ensures that even older or heavily used appliances can be assessed with confidence.
Compact, Lightweight, and Designed for Mobility
Weighing next to nothing and measuring just 26 x 10 cm, the Seaward PrimeTest 100 is one of the smallest PAT testers on the market. Despite its tiny size, it delivers all the essential functions you need to stay compliant and safe. Because it runs on standard AA batteries (6 included), you can test virtually anywhere—no need to search for a power outlet.
It‘s also easy to transport thanks to its ergonomic design and carry case, making it ideal for mobile electricians, caretakers, and onsite maintenance staff.
Testing Made Easy – Just Plug, Press, and Go
Using the Seaward PrimeTest 100 could not be more straightforward:
- Connect the appliance or extension lead you want to test.
- Choose the relevant test type: Class 1 earthed, Class 2 double-insulated, or IEC mains cord.
- Press the button.
Within seconds, a clear PASS / FAIL result is shown on the screen—making portable appliance testing fast, efficient, and hassle-free.
When plugged into a power outlet, the tester automatically checks the socket‘s wiring and mains voltage to ensure it‘s safe for use—adding yet another layer of protection.
Electrical Testing Functions – What the PrimeTest 100 Can Do
The Seaward PrimeTest 100 PAT tester includes all the core functions required for most workplace appliance testing:
- Earth Continuity Test (200mA soft test)
- Insulation Resistance Test (500V)
- 250V Insulation Resistance – new for the 5th Edition
- Mains Supply Check
- IEC Lead Testing
This makes the Seaward PAT Tester 100 an ideal solution for many common testing situations, especially in education, healthcare, hospitality, and facility maintenance.
PrimeTest 100 vs PrimeTest 50 – What‘s the Difference?
While both testers are aimed at ease of use, the Seaward PrimeTest 100 goes a step further by including alternative substitute leakage testing. This test simulates a leakage current scenario using a low voltage (typically around 40V AC). It‘s useful for identifying potential insulation weaknesses without applying full mains voltage—offering extra peace of mind during portable appliance testing.
Seaward PATMobile App – Smart Testing Made Simpler
The Seaward PrimeTest 100 works in conjunction with the free Seaward PATMobile App, available for both Android and iOS. This app unlocks a range of powerful features:
- Digital data logging of pass/fail results
- Barcode scanning
- Photo tagging
- Label printing (Android only)
Managing appliance records has never been easier. Keep digital logs, print custom labels, and streamline your portable appliance testing process without needing a PC or software subscription.
