Sealey MM405 Mini AC / DC Clamp Meter

The Sealey MM405 is a compact AC/DC clamp meter designed specifically for automotive electricians and tradespeople who need to verify current presence in restricted spaces. This specialised diagnostic tool combines current measurement capabilities with non-contact voltage detection, making it ideal for automotive electrical systems and other applications where space is limited.

Built with durable composite housing and a comfortable rubber grip handle, the MM405 delivers reliable performance in demanding workshop environments. The 18mm jaw opening is purposely designed to access tight spaces commonly found in vehicle wiring systems, whilst still measuring up to 200A on both AC and DC circuits. The backlit LCD display with 4-digit readout ensures clear visibility in all lighting conditions, complemented by an integrated LED light at the front of the unit for illuminating dark working areas.

Non-contact voltage detection provides an essential safety feature, detecting AC voltage from 100 to 600V without physical contact, whilst the frequency measurement capability (40Hz to 1kHz) adds valuable diagnostic functionality. The unit's lightweight 160g construction and compact 155 x 66 x 31mm dimensions make it highly portable, and it arrives complete with a soft padded storage case for protection between jobs.
