HH802U specifications
The Omega Engineering HH802U is a versatile handheld thermometer designed for precise temperature measurement in various environments. This device is especially favored by engineers, HVAC technicians, and laboratory personnel for its accuracy, user-friendly interface, and robust design.One of the standout features of the HH802U is its dual-channel capability. This enables users to connect two different temperature probes simultaneously, allowing for comparative measurements or the monitoring of multiple temperature points at once. This feature is particularly useful in applications like HVAC testing, where monitoring air temperature at different points is essential for system assessment and troubleshooting.
The HH802U supports a wide range of temperature probes, including thermocouples and RTDs (Resistance Temperature Detectors), giving users the flexibility to select the best sensor for their specific application. The device is compatible with several types of thermocouples such as Type J, K, T, and E, making it adaptable for various industrial and laboratory settings.
Another important characteristic of the HH802U is its impressive measurement range. The device can measure temperatures from -200°C to 1372°C, depending on the connected probe. This wide range ensures that it can handle both very low and high-temperature applications, from cryogenics to industrial processes.
The HH802U's display is equipped with a large, easy-to-read LCD screen, which shows both channels’ temperatures simultaneously, aiding users in quick data evaluation. Additionally, the device features data logging capabilities, allowing users to store temperature readings for later analysis. With its built-in memory, users can record up to 100 readings, facilitating adjustment and review over time.
The instrument also boasts a user-friendly interface, including simple controls and a menu, making it easy for even novice users to navigate through functions and settings. Its compact and lightweight design makes it portable, suitable for fieldwork, and it comes with a protective rubber boot to enhance durability.
With a battery life that supports prolonged operation, the HH802U is ideal for demanding environments where power sources may be limited.
