3 (1/2) Digital Multimeter TRms DMM With TEMP ( HTC – DM-83T )

Description

The HTC DM‑83T Digital Multimeter combines compact portability with professional-grade performance, offering a 3½‑digit display (up to 1999 counts) and True RMS measurement for accurate AC readings. Its intuitive and ergonomic design, featuring a backlit LCD with bold 20 mm digits, ensures clarity even in dim environments—making it ideal for technicians, students, and hobbyists alike.

This autoranging multimeter supports a full suite of measurement functions: DC voltage up to 600 V across ranges from 200 mV to 600 V (±0.5% + 4 digits in the 200 mV range and ±1.0% + 4 digits at 600 V); AC voltage up to 600 V RMS via True RMS detection (±0.8% + 6 digits at low voltage, ±1.0% + 6 digits on 600 V range).

Current measurement is equally versatile, offering both DC and AC ranges from 200 µA to 10 A with appropriately scaled accuracy (e.g. ±1.5% + 5 digits on high AC/DC ranges). It also provides continuity testing, diode check, transistor hFE analysis, and a built-in NCV (Non‑Contact Voltage) sensor—ensuring safe detection of live wires without direct contact.

Beyond core functions, the DM‑83T incorporates a practical built-in torch light to aid in low-light inspection scenarios, making it versatile for fieldwork and workshop use. The data hold feature allows freezing the display for hands-free observation, while automatic power‑off helps preserve battery life between sessions.

he instrument accommodates temperature measurement via thermocouple (typically supporting –40 °C to 1000 °C), enabling environmental and HVAC diagnostics. Safety is paramount: compliance with IEC 61010 standards, sampling at approximately three readings per second, auto-overrange warning (“OL”), and low‑battery indicators ensure confidence during use.

Lightweight and portable, the meters’ form factor measures approximately 140 × 72 × 37 mm and weighs ~195 g including two AAA batteries. Its compact build, along with included accessories such as test leads, holster, temperature probe, and manual, allows for quick deployment and easy storage in toolkits or backpacks.

Key performance parameters include:

• True RMS AC/DC voltage (up to 600 V) for accurate waveform analysis

• Wide current range (200 µA to 10 A) for both AC and DC measurements

• Resistance ranges from 200 Ω to 20 MΩ for circuit continuity and component testing

• Diode and continuity testing, with buzzer feedback under approximately 30 Ω

• Transistor hFE testing, NCV detection, and torch illumination for enhanced diagnostics

Applications for the DM‑83T span across professional and hobbyist fields: electrical circuit diagnostics, HVAC control testing, educational labs, electronics prototyping, and basic household or industrial maintenance tasks.

Feature Summary:

• 3½‑digit LCD, 1999 counts with backlighting
