Supported Applications

The Omega HH314A Series is a handheld digital humidity and temperature meter designed for portable measurement tasks. The device utilizes a polymer capacitive sensor, a semiconductor sensor, and a K-type thermocouple to measure environmental conditions. It features an RS232 interface enabling bi-directional communication with a PC for data logging.

Per the manufacturer's warnings, these products are not designed for use in patient-connected applications.

Operating Conditions & Performance

The HH314A Series operates within an ambient temperature range of 0°C to 50°C. It is rated for environments with relative humidity up to 90% max and altitudes up to 2000 meters.

Measurement capabilities are defined across three channels:

Humidity: Range of 0%~100%RH with an accuracy of ±2.5%RH at 25°C and a resolution of 0.1%RH.
Temperature T1 (Internal): Range of -20°C to +60°C (-4°F to +140°F) with an accuracy of ±0.7°C, ±1.4°F and a resolution of 0.1°C or 0.1°F.
Temperature T2 (External K-Type): Range of -200°C to +1370°C (-328°F to +2498°F). Resolution is 0.1°C for the -200°C~200°C range and 1°C for the 200°C~1370°C range; similarly, resolution is 0.1°F for -200°F~200°F and 1°F otherwise.

Accuracy specifications for Temperature T2 are referenced to a table not provided in the source document.

Configuration Options

The series is configured as a handheld unit with a 4-digit Liquid Crystal Display (LCD). Internal memory supports storage of up to 16,300 readings. The device includes an RS232 interface for data transfer and communication.

Display: 4 digital LCD
Data Storage: Up to 16,300 readings in internal memory
Sensors: Polymer capacitive (humidity), semiconductor sensor, and K-type thermocouple input
Communication: RS232 interface for bi-directional communication with PC
Certifications: CE marked

Key Product Differences

The HH314A-Series is represented by the single enabled variant model number HH314A. The series title identifies it as a handheld meter with USB and RS232 capabilities, though the provided specification document explicitly details only the RS232 interface for bi-directional communication.
