The Hydrajaws Bluetooth Digital system allows on-site pull tests to be automatically recorded and compiled into a digital report using the Hydrajaws Bluetooth Digital App on a mobile phone or tablet device. These reports can be sent directly to clients or managers and are stored in the cloud to be accessed remotely anywhere on a browser in a user own company dashboard.
Other models are also available for scaffolding, safety lines, braces, etc.

They have several models for different purposes. For anchors we do recommend:
DTEpico-VCH 2500: for medium loads
- Up to 25 kN.
- Simple and quick setting up.
- Reading on a digital indicator, pressure sensor with peak value. The indicator operated with one 3 volt battery (type CR2430), stopping automatically after 15 min.
- Packed in a transport case (with a set of optional accesories).
DTEpico-VCH 5000: for high loads
- Up to 50 kN.
- Simple and quick setting up.
- Reading on a digital indicator, pressure sensor with peak value. The indicator operated with one 3 volt battery (type CR2430), stopping automatically after 15 min.
- Packed in a transport case (with a set of optional accesories).

P-C-7281: for medium loads
- Up to 25 kN.
- The tensile load is applied to the fixing mechanically; hydraulics are used to register the load only. This enhances the systems reliability as it is not prone to hydraulic leaks. Also, mechanical loading provides smoother operation, eliminating hydraulic backlash.
P-C-7290M: for high loads
- Up to 100 kN.
- Maximum diameter: M20.
- The load application is achieved via a ratchet handle driving a 4:1 hydraulic multiplier; the applied load is recorded directly on a gauge mounted on the tester body. This compact design is lighter and more convenient to use than that of separate hydraulic pump and ram arrangements.
- An integral movement indication is provided allowing First Movement to be identified as well as total displacement before failure.
