The IT100 (Insta Test 100) is the newest portable handheld PAT testing unit designed by First Stop Safety. It has been designed to carry out electrical safety tests on an array of electrical appliances to confirm whether specific appliances are safe to be used. The IT100 can perform tests on 3 main types of appliances, including:
- Class I - Appliances with an Earth connection
- Class II - Appliances that are double insulated (no earth connection)
- Power Cord - Testing for IEC cables, extension leads, and multiway adaptors
The IT100 has been designed to deliver precise and accurate readings to ensure your appliances are safe and compliant for use.
The device itself carries out four basic tests. Please note that not all tests are appropriate for all types of appliances.
The tests include:
1. Earth Continuity
2. Insulation Resistance
3. Substitute Earth Leakage
4. Polarity Test
Printer
Bring even more efficiency to your IT100 PAT testing workflow with First Stop Safety's fully portable label printer, designed to let you print test labels the moment each appliance is checked.
Using the free Weprint mobile app on iPhone or Android, you can quickly enter key details such as the appliance ID and your tester name before printing.
Each label features a clear green “PASS Electrical Safety Test” header, making results easy to identify during inspections and follow‑up visits.
Built for life on the move, the printer is lightweight and battery-powered. Minimal setup is required, and our support team is always available should you need assistance.
Perfectly paired with the IT100, this printer streamlines your PAT testing process, keeping everything mobile, efficient, and neatly documented.
