All electrical tool timers are available in plug/socket, single phase or three phase 110, 230 Volt with 16 or 32 amp version. Simply attach the Castle Tool Timer to the power supply of the designated tool, and over the course of the day the timer will accurately measure how long the tool has been operating (i.e. trigger time exposure).
The measurement of vibration levels from hand-held power tools is now a fairly well prescribed process and can be carried out with reasonable repeatability. The problem still remains with the assessment of ‘trigger-time’ and this can lead to large errors in a risk assessment.
