This is a specially designed calibration control unit, which is suitable for calibrating most prestressing jacks. It features a clear digital readout and special centralising collars for use with systems up to 18mm/300kN.
The unit is supplied in an aluminium case complete with centralising collars to suit customer wire/strand requirements. The meter is self powered using an easily replaceable standard 9 Volt type PP3 battery. The non-rechargeable battery saver system will automatically shut down after 15 minutes if the unit is not used. When switched back on it will memorise reading of both Peak and Tare indefinitely. Typical battery life is 100 hours, with a minimum 50 hours.
