Joint integrity specialist Hydratight has launched a smaller, user-friendly version of its highly-regarded BoltScope ll bolt load monitoring device. The new pocket-sized BoltScope Pro brings higher levels of accuracy to the bolting professional.

BoltScope Pro is the first cost-effective ultrasonic monitoring device to measure bolt load, elongation, stress and percentage of strain at nanosecond intervals, and resolutions down to a thousandth of an inch.

Loaded and unloaded bolt readings can be compared instantly on its easy-to read screen. The device can also be configured for linear regression or vector readings to assist load measurement optimisation. BoltScope Pro can store 8,000 readings in multiple groups for detailed comparisons. Readings can be stored offline for joint integrity reporting.

New features include an autoset facility, which automatically optimises signal detection and adjusts the display accordingly; visual waveform matching so readings can be repeated with great accuracy, and a high-low alarm, which can work with the data port and an external pump shut-off device, to limit errors.

BoltScope Pro has a tough aluminium body with sealed end-caps for long service in the very toughest conditions. It is battery powered, with up to 150 hours of battery life.
