The HH11C and HH12C handheld thermometers feature Type K thermocouple inputs and are available in either single- or dual input models. The HH11C is a single-input model that has auto range resolution of 0.1 or 1°. The HH12C is a dual-input meter that allows the user to display T1, T2, or (T1 – T2) readings with 0.1 or 1° resolution. Both models have a 4½ digit display with a maximum reading of 19999, 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. Both units also have improved temperature range and humidity specifications.
