Expert Quality, non contact voltage tester with integrated inspection lamp. Suitable for identifying live wires, broken wires and fault finding. Sensitive voltage detection between the range of 100-600V. Fitted with inspection light on one end and audible/visual indicators. Powered by 2 x AAA batteries (supplied). Display packed.

Safe and simple to use, the 'BUZZ-IT' from Martindale is a real improvement for awkward sockets. It has an audible signal to tell you instantly whether or not the wiring is correct, and can also be used as a fuse finder, as the correct fuse is located when the buzzer stops.

If there is a problem the pattern of LEDs indicates the fault. Any results other than three indicators lit and a continuous buzzing tone shows a fault condition.

• Housed in a sculptured, flame retardant ABS case for easy insertion and removal
• Size 65 x 65 x 47mm

Classic socket tester plug from Martindale with neon indicators in ABS housing. The plug induces less than 5mA of earth leakage, well below RCD trip thresholds. As with all socket testers the plug only verifies the presence of an earth, but does not assess its quality.

• Ergonomically designed case moulded in high density, flame retardant ABS
• Easily gripped for ease of insertion and removal
• Ideal for electricians and safety checks
• BS EN 61010 cat II 300V compliant
• 1.2W power consumption
• -10°C to +40°C temperature range
• Size (L x W x H) 65 x 65 x 47mm

The Matindale EZ165 not only detects 28 fault conditions and checks the mains voltage level, it also shows how safe the earth wiring is by carrying out a non-trip earth loop test and indicates its value in 6 discrete ranges from less than 1.7Ω to 500Ω. A low earth resistance is essential for safety disconnection devices to work properly and to prevent electrocution when faults occur.

In contrast, basic socket testers only detect the presence of an earth with some products showing an earth connection even when resistance values are as high as 500kΩ. The EZ165 is defined as an Advanced Socket Tester by the Health & Safety Executive.

• Key features:
• Quick & easy mains socket polarity and earth testing
• High/low voltage indication
• Red/Green LEDs indicate 28 fault conditions
• Non-trip earth loop impedance test
• Tough sculpted design for easy removal
• Martindale type EZ165

The Martindale CP301 is designed for use on 110V centre tapped circuits, it is fitted with a yellow 110V 16A CT plug to BS 4343/IEC309. The CP301 shows similar fail-safe indications to the classic Martindale check plug.

Using LEDs to highlight possible fault combinations, the CP301 is invaluable for instantly checking sockets in factory or on site installations.

• Operating Voltage: 110V AC (55-0-55V centre tapped supply)
• Operating Current: 30mA
• Overvoltage: CAT II, 150V
• Weight: 180g approx
