Useful for pubs, bars and other smoking areas, this tamper proof meter is designed to switch up to 80A of heaters (30kW) at a time at the drop of a coin or token. The timed 'On' can is pre-determined by the user; for example £1 for 15 minutes of heater use for a smoking area, and then it will automatically switch them off. Alternatively a token version is available where the value of the tokens can be varied at will in combination with the timer.
