Description

The HH-20A series microprocessor-based handheld thermometers offer wide-ranging temperature readings and feature state-of-the-art innovations. The easy-to-read custom 5-digit LCD readout with trend display and self-diagnostics are all standard. The case is drop/splash and dust-proof, and has a built-in tilt stand/handle for bench use or hands-free field measurements.

The HH-21A is a single input unit that accepts J, K and T thermocouple types. From the front panel, the user can select the thermocouple type, display units (°C or °F), and display resolution (0.1° or 1°). The HH-21A also has a display hold function. As with all HH-20A series units, the HH-21A features exceptionally high accuracy, 0.1% of reading plus 1°F.

The HH-22A and HH-23A accept dual inputs. The HH-22A accepts either J or K thermocouples, while the HH-23A works with J, K or T types. Both models can display T1 (input 1), T2 (input 2), T1-T2 (difference), or scan between T1, T2 and T1-T2. Standard features for both the HH-22A and HH-23A include display hold, min and max storage, and trend indication. The min and max functions record minimum and maximum values for T1, T2 and T1-T2. Trend indication shows if the displayed input is increasing, decreasing or stable.

When you turn on an HH-20A, it remembers what you were doing; the thermocouple type, resolution, and temperature units are stored in non-volatile memory so you don’t have to reprogram every time you start up
