HH12C is a high accuracy dual input digital thermometer feature Type K thermocouple inputs. The HH12C is a dual-input meter that allows the user to display T1, T2, or ∆T (T1 – T2) readings with 0.1 or 1° resolution. It has a 41 ⁄2 digit display with a maximum reading of 19999, °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.
