1. Introduction

The UTi80P thermal imager is a pocket-sized and lightweight device. This device is able to find hidden hot spots, energy loss, structural defects, pipe jams, HVAC faults and other problems through analyzing the thermal image of a surface. It can measure temperatures up to 400°C and quickly displays the result on the LCD screen. With data recording, analyzing, and report generating functions, the UTi80P is an ideal measurement tool for professional fields requiring temperature analysis.

2. Safety Instructions

To ensure accurate measurement results, please read the instructions carefully.

Please be sure to use this product in accordance with the instructions, otherwise the free warranty will be voided if the product is damaged.

Please do not use this product in flammable, explosive, steamy, wet or corrosive environments.

Please stop using the product if it is damaged or modified to avoid inaccurate test results.

Please use the correct emissivity value in order to obtain accurate temperature readouts.
