Viewport encourages preventive
maintenance
The patented Viewport is the first UL-approved device to allow closed-door infra-red inspections of electrical panels.
Mikron Infrared's patented Viewport is the first UL-approved device to allow closed-door infra-red inspections of electrical panels Matched with Mikron's SpyGlass fisheye lens, it allows an inspector to scan a panel by looking through a single port's tiny 0.62in opening

High-resolution cameras cut cost of IR imaging
Mikron is claiming a first in infra-red imaging technology for predictive maintenance applications with its new M7800 and M7815 cameras.
Designed to make frequent inspections more convenient, the Viewport enables a thermographer to work without the help of an electrician or safety barricading, and with minimal personal protective equipment.
The Viewport is also excellent for use with ultrasound detection equipment.
Thermal scans through the Viewport are highly accurate, because the unique open design needs no IR-transparent window or metal screen that can skew readings by the IR camera.
When used with the plastic-tipped SpyGlass lens, there is no "path to ground" through the camera, enhancing operator safety.
The Viewport is unaffected by moisture, dirt, UV or corrosive environments that can destroy IR windows.
UL-approved for installation on NEMA type 1, 2, 3, 3R, 4, 5, 12,12K and 13 enclosures, the Viewport is ideal for OEM use or retrofit in the field.
Installation requires 20min or less.
The Viewport has received UL approval number NITW2.E228318 in the USA and NITW8.E228318 in Canada.
"Plant maintenance people simply make more frequent infra-red inspections, when it is safe and convenient to do so", said Mikron Sales Vice President Jon Chynoweth.
"Early users have documented hundreds of thousands of dollars in savings from unscheduled outages and lost production".
Three styles of the Viewport are available, with a list price starting under $50 - the lowest in the industry, according to the manufacturer.
The standard Viewport model is closed with a protective O-ring-sealed, screw-on cap when not in use.
Other models include a locking device or a window with a locking device.
The SpyGlass fisheye lens, with its wide field of view (53 degrees horizontal by 40 degrees vertical, or 66 degrees diagonal), allows easy scanning of the interior of the electrical cabinet through the Viewport, providing a temperature measurement accuracy of +/-3C.
With a focus range of 100mm to infinity and a large depth of field, the SpyGlass lens reduces the need to refocus for different electrical cabinet depths.
