Humidity & Temperature Meter ( HTC – HT-306 )

Description

HT-306 ( Humidity & Temperature Meter ) – Professional-Grade Precision in a Compact Design

The HTC HT-306 is a versatile digital instrument engineered for accurate measurement of both temperature and humidity, making it an ideal choice for HVAC professionals, laboratory technicians, environment specialists, and quality control teams. Its intuitive dual-display interface, rugged build, and wide measurement ranges deliver reliable performance across indoor and outdoor environments.

Dual Display & Efficient Readouts

At the heart of the user experience is the large dual digital LCD display, complete with backlighting for improved visibility in poorly lit conditions. This sophisticated interface presents both humidity and temperature readings simultaneously, minimizing the need to toggle modes. It also includes intuitive status indicators—like MAX, MIN, RELATIVE, and HOLD modes—within the display, enabling users to interpret measurements quickly and confidently.

Fast Sampling & Responsive Accuracy

With a sampling rate of 2.5 samples per second, the HT-306 delivers near real-time updates—ideal for dynamic testing scenarios where temperature or humidity levels change rapidly. The humidity sensor operates across a wide range of 5% to 98% RH, featuring a fine 0.1% resolution and a guaranteed accuracy of ±3.5% RH—sufficient for sensitive monitoring and environmental control.

Wide-Range Temperature Sensing via Type-K Probe

Paired with a Type-K thermocouple probe, the HT-306 offers an impressive temperature measurement span from –20.0 °C to 1000 °C (or –4.0 °F to 1832 °F). It allows for precise readings, with an accuracy of ±3.0% of the reading plus 4 °C (or 7 °F), enabling confident use in conditions ranging from ambient air monitoring to high-temperature industrial processes.

Enhanced Functionality for Professional Use

To enhance diagnostic capability, the meter includes features like MAX/MIN capture, relative value (REL) displays, data hold, and MAX hold modes—helping users capture and compare environmental extremes at a glance. The auto power-off feature conserves battery life by shutting down the device after periods of inactivity, while the low-battery indicator ensures users are alerted when it’s time to replace the 9 V battery.

Rugged Build, Compact Form & Accessories

Despite its robust functionality, the HT-306 maintains a compact footprint of 225 mm (H) × 45 mm (W) × 34 mm (D) and weighs approximately 210 g, making it highly portable and perfect for field operations. Each unit comes pre-equipped with a carrying case, the Type-K temperature probe, and a user manual, ensuring ready-to-go deployment right out of the box. Power is supplied via a single 9 V battery, offering straightforward handling and replacement.

Ideal Applications Across Industries

The HTC HT-306 excels in diverse contexts where accurate humidity and temperature data are essential:

• HVAC maintenance: Diagnose system performance, check duct air temperature, and regulate humidity in critical zones.

• Laboratory & research environments: Monitor controlled atmospheres, incubators, and material storage conditions.

• Industrial processing: Track environmental parameters in drying processes, ovens, or climate-sensitive production lines.

• Agriculture & greenhouses: Maintain ideal growing conditions for plants, seeds, and crops.

• Archives & storage monitoring: Ensure optimal climate settings to safeguard artifacts, documents, and sensitive materials.

• General environmental auditing: Conduct quick, portable checks of indoor or outdoor climate conditions.

With its responsive sampling, dual-display layout, and rugged design, the HT-306 is perfectly suited for technicians and field personnel who need reliable environmental readings in demanding scenarios.

Why the HTC HT-306 Stands Out

By integrating fast sampling, dual-parameter display, accuracy, and portability, the HTC HT-306 offers an all-in-one solution for professional-grade environmental measurement. Its precise humidity sensing and wide-range Type-K temperature probe make it particularly valuable in industrial, lab, and climatic investigation scenarios. The thoughtful interface and sturdy construction ensure both ease of use and long-term reliability making the HT-306 a trusted companion for technicians, researchers, and professionals across sectors.
