HSE expects Commissioning Engineers to physically check the rotation speed of fans during Commissioning/Initial Examinations & Tests (TExTs) and to record this value in their Reports.
It’s not always possible to use a ‘contact’ tachometer and we have sourced these simple ‘contactless’ digital tachometers which will do the job in most cases.
Inexpensive and easy to use.
Simply apply a small piece of the reflective tape (supplied) to a visible moving part of the fan/drive assembly, point the device and read the speed 🙂
