Description
TEK100 Non-Contact AC Voltage Detector (100–600V)
The TEK100 Non-Contact Voltage Detector is a simple, reliable tool designed to quickly identify the presence of AC voltage without the need for physical contact with a conductor.
Suitable for detecting 100V to 600V AC, the TEK100 provides clear feedback through both a red visual indicator and an audible tone, allowing you to work confidently even in noisy or poorly lit environments.
For added safety and peace of mind, the TEK100 features an integral self-test function. This activates the sensor in the tip at 50Hz while also checking the battery and LED. Unlike basic testers, this process verifies the entire circuit, not just the indicator light, ensuring the tester is functioning correctly before use.
Compact and easy to use, the TEK100 is an essential voltage detection tool for everyday electrical checks, fault finding, and safety verification.

⏱ 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)
