With their powerful features, the portable and rugged high-temperature OS523E/524E Series infrared thermometers offer solutions for many non-contact temperature measurement applications. Their emissivity, adjustable in 0.01 increments, allows them to measure a variety of surfaces. A custom backlit LCD features dual digital display of the current and max, min, difference, or average temperatures simultaneously. Standard features include high and low audible and visual alarms, 1 mV/degree analog output, RS232 output, and temperature data storage.

Rated 5 out of 5 by from Quality and Reliable Thermal detection This is the second OMEGA product purchased for my current institution. The procurement department and customer service through the process was seemless and shipping was performed next day. The performance of the product allows me to gain accurate readings of our 2400F thermal combustion coal ovens, in order to perform repairs relative to the oven surface temperature. Our quality of repairs would not be possible without accurate and reliable reading from the OMEGA product lines.

Does the OS523E-3 come with the NIST-traceable calibration? I don't see that it's listed as an accessory and we need that.

Do you have any products that can give an accurate temp reading through mill scale?

Asked by: Tlpp
Thank you for your inquiry. Unfortunately we don't have a handheld unit that can measure that surface.

What is this for kind sir? Why a scope?

Asked by: RodgerDodger3000
Thank you for your interest in our product. It provides a visual indication of the target being measured. Aiming at distant targets (up to 200 feet) becomes much easier by using the Sighting scope.

What type of connection is used for the analog output?

Asked by: DavidT76
Analog out uses a connector similar to 3.5mm mono connector Best regards OMEGA
