The pressometer is designed to measure the closing forces of powered doors on passenger-carrying vehicles. The unit provides a straightforward pass or fail indication of the measured force according to the measurement guidelines and force limits set out in revision 3 of the United Nations 1958 Agreement, Addendum 106, Regulation 107.
The pressometer is intended for use by bus manufacturers and can also be used in maintenance workshops and test stations. The unit is of robust construction and has overload protection for the force measuring load cell, making it fit for shop floor use.
The body of the pressometer is provided with a resilient coating and the parts that contact the door are sleeved with nylon in order to minimise the risk of marking the vehicle on test. For convenience in use, the unit is powered by rechargeable batteries and may also be operated while the unit is charging from the supplied mains adapter.
When equipped with an optional reaction device, the pressometer may also be used to check the force exerted by a power-operated wheelchair access ramp.
