Built for the Desktop, Not the Back Room

The Sekonic SR-450 is a mark-reading-only OMR scanner sized to sit right on your desk. It's the model of choice when you need dependable, accurate reading for smaller batches — short exams, feedback forms, surveys or evaluation sheets — without the footprint or cost of a high-volume floor scanner. Density detection distinguishes genuine marks from erasures, and built-in error detection catches no-mark, multi-mark, jam and double-feed issues as they happen, so bad reads don't slip through.

SR-450 Features

Everything built in to keep compact-batch OMR reading fast and dependable

Short-Time Operation

Reads approximately 150 forms per minute, with up to 200 forms set on the hopper at once — enough for most single-batch runs without a reload.

Accurate Reading

Density detection distinguishes a genuine mark from an erasure, and the scanner flags errors — no mark, multiple mark, jam, double feed — as they're read.

Compact Design

Small enough to sit on a standard desktop, making the SR-450 a natural fit for private offices and lower-volume, everyday reading work.

Inherited Compatibility

Stays compatible with the older SR-430, SR-410 and SR-307 models, so it can run with the conventional software you already have in place.

Optional Visible-Light Sensor

A visible-light sensor variant is available for reading black or blue ballpoint pen marks, in addition to standard pencil marks.

Standout Feature

Automatic Paper Thickness Setting

The SR-450 memorizes the paper thickness of the very first form it reads and stores it as the standard value for the rest of the batch — cutting the risk of a mis-set thickness ruining a read, without any manual calibration step.
