Thermometer

1  Introduction

1.1  About this guide

This guide gives the information necessary for you to operate a LAND UNO 

thermometer.  Basic information regarding installation is contained within the 

Installation Guide.

1.2  About the thermometer

The LAND  UNO  thermometer is a highly accurate, focusable, non contact 

thermometer designed for independent or STAND ALONE use.
The thermometer features include:
• 

Stand Alone operation.

• 

Built in Averager or Peak Picker for signal conditioning.

• 

Focusable optical system with through-the-lens sighting to give precise 

target definition.

• 

4 to 20mA output, linear over the temperature span of the thermometer.

• 

Built in Emissivity or Non Greyness controls.

1.3  About UNO

The LAND UNO range of high accuracy thermometers and rugged mounting 

accessories is designed to provide precise, non contact temperature 

measurement.
Internal controls for emissivity or non greyness, together with selectable 

time functions, allow the thermometer to be configured to suit a wide range 

of industrial applications.   A comprehensive range of mountings is common 

to other LAND products maximising commonality and simplifying system 

upgrades.

1.4  Unpacking the thermometer

The package containing the thermometer will contain the following items:
• 

CD containing UNO User Documentation.

• 

UNO thermometer (fitted with protection caps on the lens and eyepiece).

• 

Eye comfort filter.  Fitted only to instruments where the temperature 

range exceeds 1600°C/2900°F.

• 

The thermometer will be supplied pre-fitted with either a Standard lens 

(denoted VG/VC) or a Short Focus lens (denoted SG/SF).

• 

2.5mm Hex screwdriver.

• 

2.5mm flat blade screwdriver.

It is recommended that the front lens protection cap is kept attached until the 

thermometer is installed and that the eyepiece cap continues to be used after 

installation.
