The HH11B and HH12B handheld 
thermometers feature Type K 
thermocouple inputs and are 
available in either single- or dualinput models. The HH11B is a 
single-input model that has auto 
range resolution of 0.1 or 1°. The 
HH12B is a dual-input meter that 
allows the user to display T1, T2, or 
∆T (T1 – T2) readings with 0.1 or 1° 
resolution. Both models are °C/°F 
switchable and feature front-panel 
offset adjustment and maximum 
reading/display hold functions. 
Errors contributed by a particular 
thermocouple can be practically 
eliminated, over a limited range, by 
using the recessed offset adjustment 
on the face of the meter and an 
accurate temperature standard.  
An LED warning light indicates 
when an open thermocouple input 
situation exists.
