Extech TH30 USB Dual Temperature Datalogger

This model is designed for monitoring and logging temperature over time from two channels—its own built‑in sensor plus a flexible external probe (included). With its built‑in USB connector, once a logging session is complete you can plug it directly into your PC to transfer data (no special drivers required). The housing is rugged and portable, making it suited for field use, transport monitoring, environmental checks, and equipment diagnostics. Users can programme various settings: sampling interval (from 30 seconds up to 120 minutes), start‑delay, high/low alarms, bookmark up to eight locations in a log, choose between six languages, and apply password protection. The display shows real‑time temperatures, and status is indicated by a dual‑colour LED (green for normal/logging, red for alarms). Once data is transferred to a PC, the software helps you generate nice reports with graphs. With battery life of around three months (on two CR2032 coin cells), it’s ready for medium‑term deployments. The external probe gives flexibility to monitor a specific point (for example inside a cabinet, near a component, or inside a shipping container) while the internal sensor monitors ambient conditions. All together it’s a versatile tool for temperature tracking applications where logging and later review are required.

Features

• Dual temperature channels: built‑in internal sensor + external probe (TP830 or equivalent) for simultaneous monitoring of two points.

• Large memory capacity: up to 48,000 data points total (24,000 per channel) for extended logging sessions.

• USB interface for direct data download to PC in PDF or Excel formats—no extra interface required.

• Programmable sampling interval: from 30 seconds up to 120 minutes; configurable start delay, high/low alarm thresholds, bookmark function (up to 8 bookmarks) and multiple language support.

• Real‑time display: 5‑digit LCD shows current temperatures, MAX/MIN modes; dual‑colour LED status indicator for logging and alarm states.

• Compact and lightweight: example dimensions ~110 × 40 × 19 mm, weight ≈ 90 g, powered by two CR2032 batteries, battery life approx. 3 months under typical use.

• Temperature measurement range (built‑in & probe) roughly –30 °C to +70 °C (–22 °F to +158 °F) with resolution 0.1° and accuracy ~±0.5 °C.

• Rugged mounting/hanging options: built in hanger and USB cap that can double as a stand for desktop use.
