Description

Humidity & Temperature Meter with Dew Point (HTC – HD-304)

The HTC HD-304 Humidity & Temperature Meter with Dew Point is a versatile environmental measuring instrument designed for monitoring important atmospheric conditions such as ambient temperature, dew point temperature, and wet bulb temperature. With its fast response time, large-screen LCD, backlight, automatic power-off function, and 99-group data logging capability, the HD-304 is suitable for professionals and users who require convenient and reliable environmental measurements.

Temperature and humidity are important parameters across numerous industrial, commercial, storage, HVAC, laboratory, agricultural, and building-management applications. Monitoring these conditions can help users evaluate environmental comfort, identify moisture-related problems, assess condensation risks, and maintain appropriate conditions for equipment, materials, products, and processes.

The HD-304 combines multiple environmental measurement functions in a single compact handheld instrument, making it convenient for technicians, engineers, maintenance professionals, facility managers, HVAC personnel, inspectors, and general-purpose users.

Ambient Temperature Measurement

The HTC HD-304 provides ambient temperature measurement, allowing users to monitor the temperature of the surrounding environment. Ambient temperature information can be useful for evaluating workplace conditions, equipment environments, storage areas, rooms, production spaces, and other locations where temperature monitoring is required.

Fast response performance allows the instrument to react quickly to changes in environmental conditions, making it practical for field measurements and routine inspections.

Dew Point Temperature Measurement

One of the important functions of the HD-304 is dew point temperature measurement. Dew point is the temperature at which air becomes saturated and moisture can begin to condense. Monitoring dew point can therefore be useful for identifying potential condensation conditions.

Dew point information is particularly valuable in applications involving HVAC systems, air-conditioning, cold storage, warehouses, industrial facilities, laboratories, building inspections, and moisture-sensitive environments.

By monitoring ambient temperature together with dew point conditions, users can better understand the relationship between air temperature and moisture in the environment.

Wet Bulb Temperature Measurement

The HD-304 also provides wet bulb temperature measurement. Wet bulb temperature is an important environmental parameter used in various applications involving humidity, evaporation, ventilation, and thermal conditions.

Wet bulb measurements can be useful in environmental monitoring, HVAC assessment, industrial applications, and certain process and laboratory environments where understanding the combined effect of temperature and moisture is important.

The availability of ambient temperature, dew point temperature, and wet bulb temperature in one instrument makes the HD-304 a convenient multifunctional environmental meter.

Large LCD with Backlight

The meter features a large-screen LCD display designed for easy viewing of measurement values. A large display is particularly useful during field inspections where users may need to quickly read values while moving between different measurement points.

The integrated backlight improves display visibility when measurements are taken in low-light conditions. This can be useful in warehouses, plant rooms, service areas, equipment rooms, HVAC installations, workshops, and other locations where lighting may not be ideal.

Fast Response Time

The HD-304 is designed with a fast response time, allowing users to observe environmental changes efficiently. Fast response is useful when moving between different locations or when monitoring changing environmental conditions.

For technicians conducting inspections, a responsive instrument can make measurements more convenient and reduce the waiting time between measurement points.

99-Group Data Logging

A key feature of the HTC HD-304 is its 99-group data logging capability. Data logging allows users to record and retain multiple measurement sets for later reference and comparison.

The 99-group memory can be useful during environmental inspections where measurements need to be taken at several locations. Instead of manually recording every reading immediately, users can store measurement data in the instrument and review the recorded information as required.

This feature can support routine inspection, environmental surveys, HVAC assessments, storage-area monitoring, and other applications where multiple readings are collected.

Automatic Power Off

The Auto Power Off (APO) function helps conserve battery power when the instrument is not being actively used. This is particularly useful for portable instruments that are frequently carried between different work locations.

Automatic power management can help reduce unnecessary battery consumption and improve convenience during routine field use.

Portable and Practical Design

With dimensions of approximately 184 mm × 60 mm × 29 mm, the HD-304 is designed as a compact handheld environmental measuring instrument. Its relatively slim form factor makes it convenient to carry in a tool kit, equipment bag, or during routine inspection activities.

The instrument operates using three AA 1.5V batteries, providing a commonly available power source for portable operation.

Wide Range of Applications

The HTC HD-304 Humidity & Temperature Meter can be used across a variety of environments and applications, including:

• HVAC and air-conditioning inspection
• Building and facility maintenance
• Industrial environmental monitoring
• Warehouses and storage facilities
• Laboratories
• Manufacturing areas
• Cold-storage environments
• Moisture and condensation assessment
• Commercial buildings
• Workshops and service areas
• Agricultural and environmental applications
• Equipment-room monitoring
• General temperature and humidity-related inspections

Standard Accessories

The HTC HD-304 is supplied with a hard carrying case and user manual, helping users protect and transport the instrument conveniently while providing operating guidance.
