The Honeytek HK830 is a portable digital thermo-hygrometer designed to monitor both ambient temperature and relative humidity in one compact device. Covering -30°C to 60°C (-22°F to 158°F) and 0%RH to 100%RH, the HK830 is the right choice for indoor climate monitoring, HVAC balancing, warehouse management, agriculture, and laboratory environmental checks.
With a 3-digit LCD display and 0.1° / 0.1%RH resolution, the HK830 delivers accurate, easy-to-read environmental data at a glance. Its lightweight 105g body fits comfortably in hand or pocket, while Data Hold, MAX/MIN, and auto power-off functions simplify everyday monitoring tasks. For distance-based surface measurements, explore Honeytek’s laser infrared thermometer range, including the HK8866 high-temperature model and HK8861 adjustable-emissivity thermometer.

How to Choose
Choose HK39T when you need to measure surface or contact temperatures across a very wide range — from freezer-cold metals to hot engine parts, furnaces, or electrical equipment. It is the right tool for technicians, mechanics, and industrial maintenance teams.
Choose HK830 when your priority is monitoring the surrounding air conditions, including both temperature and relative humidity. It is ideal for HVAC engineers, facility managers, farmers, warehouse operators, and indoor environment professionals.
For applications that require both surface temperature scanning and environmental sensing, Honeytek recommends combining the HK39T or HK830 with tools from our laser distance meter collection and infrared thermometer series to build a complete diagnostic toolkit.
