What Our Customers Say

★★★★★

"The GSW Series acoustic camera has transformed our substation inspection program. We identified 3 critical PD faults in our first week of use that would have caused major outages. Excellent product and fast shipping."

M
Michael R.
Electrical Engineer, US Power Utility
★★★★★

"Ordered the PT II Series for our thermography team. The 1280x1024 resolution is outstanding — we can now inspect transformer bushings from a safe distance and still get accurate temperature readings. Great value for money."

S
Sarah K.
Maintenance Manager, Industrial Plant, UK
★★★★★

"The SF6 Series camera helped us locate a leak in our GIS switchgear that had been undetected for months. The QWIP detector sensitivity is exceptional. Unitech Tools team was very responsive and helpful throughout."
