It is the policy of OMEGA Engineering, Inc. to comply with all 
worldwide safety and EMC/EMI regulations that apply. OMEGA 
is constantly pursuing certification of its products to the 
European New Approach Directives. OMEGA will add the CE 

mark to every appropriate device upon certification. 
The information contained in this document is believed to be 
correct, but OMEGA accepts no liability for any errors it 
contains, and reserves the right to alter specifications without 
notice. 

WARNING:

 These products are not designed for use in, and 

should not be used for, human applications. 

INTRODUCTION

 

The instrument is a portable digital thermometer that 

measures external thermocouples of type K, J, R, S, T, E, 
N. The thermocouples types comply with the N.I.S.T. – 
ITS 90 standard reference temperature/voltage tables. 
The thermometer features a dual thermocouple input, an 
adjustable T/C offset and an USB interface for uploading 
data to a PC using optional software and cable.

 

 

SAFETY INFORMATION 

WARNING 

To avoid electrical shock, do not use this instrument 

when working voltages at the measurement surface 

over 24V AC or DC.

 

 

WARNING 

To avoid damage or burns, do not make temperature 

measurement in microwave ovens.

 

 

CAUTION 

Repeated sharp flexing can break the thermocouple 

leads. To prolong lead life, avoid sharp bends in the 

leads, especially near the connector.
