Digital Thermometer ( Single Input ) – ( HTC – DT-302-1 )

Description

The HTC DT‑302‑1 Digital Thermometer is a high-precision instrument tailored for professionals in food processing, laboratories, HVAC systems, industrial maintenance, and scientific research. Equipped with automatic K‑type thermocouple compatibility, it offers measurements from –50 °C up to 1300 °C (or –58 °F to 2372 °F) across multiple ranges, combining fast responsiveness, exceptional accuracy, and robust portability into a single handheld device.

Designed for clarity and ease of use, the meter features a large 3½-digit (1999‑count) LCD display with polarity symbols, over‑range indicators, and a low‑battery alert, ensuring users receive accurate feedback instantly and reliably.

Temperature can be displayed in either °C or °F, with selectable resolution of 0.1° for –50 °C to 199.9 °C and 1° for higher ranges, allowing detailed measurement in low-heat contexts and extended range performance for high-temperature applications.

Accuracy is a standout feature: in the –50 to 199.9 °C range, the DT‑302‑1 achieves ±(0.2% of reading + 1 °C); from –50 to 1000 °C, it maintains accuracy at ±(0.3% + 1 °C); and for temperatures beyond 1000 °C, accuracy remains robust at ±(0.5% + 1 °C). When in Fahrenheit mode, accuracies are similarly rigorous: ±(0.3% + 2 °F) for low ranges and ±(0.5% + 2 °F) for high ranges, ensuring dependable performance across diverse environments.

Operation is streamlined with a Data Hold function, allowing users to freeze readings for convenient recording or further analysis. The device samples data at approximately 2.5 times per second, delivering quick updates for dynamic environments. It also features over‑range messaging (“1” or “–1”) and polarity display to ensure clarity while measuring.

Built for rugged environments, the DT‑302‑1 traps its electronics in a drop‑preventing holster-style housing with ergonomic contours for comfortable hand use. It runs on a 9V battery, providing up to 200 hours of usage with alkaline cells (and around 100 hours with carbon). A dedicated low battery indicator prevents unexpected power-downs mid-use.

Designed for versatility, the thermometer supports a wide variety of K‑type probes—such as TP01 (bead type for narrow spaces), TP02/TP03 (liquid/semisolid and surface types)—each constructed for high-temperature stability and durability. Probe accuracy ranges from ±0.3 °C to ±1.5 °C depending on type, making the device suitable for precise measurements in labs, culinary settings, and industrial monitoring.

The DT‑302‑1’s compact footprint (approx. 130mm × 95mm × 28mm) and lightweight design (about 240 g including battery) make it highly portable and ideal for handheld field use. Its robust build includes protection for harsh conditions—though users are advised to avoid extreme humidity, temperature swings, or direct exposure to heat sources during operation.

Safety measures are integrated throughout. The thermometer limits maximum allowed input voltages to 60 V DC or 24 V AC at the thermocouple terminal to prevent misuse. A warm-up period of approximately 3 minutes is recommended after power-on or probe connection to stabilize readings and ensure accuracy.

This thermometer is a reliable companion in applications such as food industry temperature checks, HVAC system validation, laboratory thermal profiling, surface temperature verification, and high-temperature engineering analysis. Its wide coverage up to 1300 °C, combined with high reliability in reading accuracy even under harsh conditions, makes it a trusted tool for professionals.

In summary, the HTC DT‑302‑1 Digital Thermometer delivers best-in-class performance with its wide temperature range, precision accuracy, clear display, responsive design, and durable, handheld form. With features like data hold, multiple probe compatibility, automatic polarity and over‑range indicators, and long battery life, it becomes an indispensable choice for users needing reliable temperature diagnostics across industrial, culinary, and scientific domains..
