HH414 Handheld Temperature/Humidity Meter w/USB 32K pt. Data Logger
Handheld Temperature /Humidity Meter with USB 32K pt. Data Logger
Supported Applications
The Omega HH414 is a handheld temperature and humidity meter with USB data logging capability. It measures temperature using a single K-type thermocouple input (T2) and relative humidity via an included remote sensor probe (T1). The device supports off-line recording of up to 32,000 points for later analysis on a PC.
Documented functions include:
• Simultaneous display of temperature from the K-type thermocouple and relative humidity/temperature from the remote probe
• Data logging with real-time clock functionality
• High/Low alarm settings for T1, T2, and RH inputs
• Max, Min, AVG (average), REL (relative to reference), and Hold calculations
• Tripod mounting capability via a threaded mount on the meter body
Operating Conditions & Performance
The HH414 operates within an ambient temperature range of 0~50°C (32 to 122°F) at less than 80% RH. Outside this operating window, specifically from 0°C to 18°C and 28°C to 50°C (32°F to 64°F and 82°F to 122°F), the temperature coefficient is specified as 0.1 times the applicable accuracy specification per °C.
Measurement ranges and accuracies are defined by input type:
• K-Type Thermocouple (T2): Range of -200~1370°C (-328~2498°F). Accuracy is ±(0.3% rdg + 1°C/2°F) for the range -50~1370°C; otherwise, accuracy is ±(0.1% of rdg ±2°C) at 23±5°C and <75% RH.
• Remote Temperature (T1): Range of -20~60°C (-4~140°F). Accuracy is ±0.6°C (1.2°F).
• Remote Relative Humidity: Range of 0.0~99.9%. Accuracy is ±2.5% at 25°C and <70%; otherwise, accuracy is ±5%.
Resolution for the remote temperature/humidity probe is 0.1°C/°F and 0.1%. For K-type inputs, resolution is 0.1°C/0.1°F in the range -99.9~199.9°C; otherwise, it is 1°C/1°F.
Configuration Options
The HH414 series includes a fixed configuration with specific inputs and connectivity options:
• Sensor Inputs: Single K-type thermocouple input via standard SMP type miniature connector; Remote temperature/humidity probe connected to the right port.
• Data Interface: USB interface for data download using Windows® based software (Windows XP or above).
• Power Supply: 9V battery. An AC/DC adaptor is available as an option; do not use both simultaneously to avoid damage.
• Included Accessories: One K-type bead wire sensor, one remote temperature/humidity probe (180 mm overall length with 150mm cable), USB cable, black carrying case, and manual website card. Calibration certificate is available as an option.
The meter dimensions are 180 x 68.5 x 50 mm. The remote sensor probe measures 180 x 12 x 10 mm with a diameter of 12 mm and includes a 150mm cable.
Key Product Differences
The HH414 is offered as a single model number (HH414) within this series. The device features a four-variable display to show temperature from the handheld probe, humidity from the remote sensor, and K-type thermocouple readings simultaneously.
- New compact hand held size measures and records single thermocouple K type with 1 meter remote temperature
- Applying to duct measurements or harsh environment.
- Quick response and high accuracy single input thermocouple and extend TRH probe.
- Relative function to compare the reference temperature per second.
