HAVi Vibration Exposure Timer

Monitor your employee's vibration exposure with the HAVi

Working with vibrating machinery tools can cause hand-arm vibration syndrome (HAVS) and, according the Control of Vibration at Work Regulations (2005), exposure must be monitored to ensure daily exposure limits are not exceeded.

The HAVi Vibration Exposure Timer is one of the simplest ways to manage the vibration exposure of your workforce, ensuring the continued health of your tool operators.

The vibration magnitude level of the tools in use must be inputted into the HAVi Vibration Exposure Timer. To measure the vibration magnitude level of your tools, use the Vexo H Hand Arm Vibration Meter.

How to use the HAVi Vibration Exposure Timer

The HAVi is simply strapped to the machine being used either by cable ties or with the fabric tie provided. Once the HAVi is running, the trigger times are continually monitored and displayed using the HSE points system.

Once an operator reaches 100 HSE points, the HAVi triggers an amber warning light and they are advised to take a break. Once an operator reaches 400 HSE points, the HAVi triggers a Red warning light advising the operator to stop using any tools that vibrate for the remainder of the day.

Once work is completed, the number of points and duration of use are recorded in a log book. It really is that simple to use and that's why the HAVi doesn't cost the earth. The HAVi's battery life lasts 1,000 trigger time hours, or an expected operation life of 2 years.

HAVi Durable Vibration Exposure Timer

The all new HAVi Durable provides a protective casing around your new HAVi device, keeping your new purchase in full use.

    This is an official review from the Castle Group team.

    The HAVi is one of our best selling instruments and seemingly a favourite with many HAV aware companies. This is likely because of the ease of use of the timer, simply power on the instrument once and you are ready to start timing exposure. Exposure is then calculated by the HAVi and translated into HSE exposure points, allowing the user to know when they are reaching the Action Value (100 points), and the Limit Value (400 points) through the bright LED flashing light.

    Consider a heavy duty case, or upgrade to the Durable if you want assured longevity.

    We would very highly recommend this as a useful tool to assist newcomers to Hand Arm Vibration.
