Testo 872 Thermal Imager

Overview

The Testo 872 is a compact, pro-grade thermal imager for industrial and building thermography. It captures 320 × 240 IR images (to 640 × 480 with SuperResolution) with thermal sensitivity down to 0.06 °C (60 mK). Use it to spot thermal bridges, leaks, overloaded circuits, and HVAC imbalances—quickly and accurately.

Key Features

• High detail: 320 × 240 IR; up to 640 × 480 via SuperResolution.
• High sensitivity: detects differences from 0.06 °C.
• Built-in laser & visual camera: precise target marker + parallel real image.
• Hot/Cold Spot: automatic highlight of critical temperatures.
• IFOV warner: shows actual measurable spot to avoid distance errors.
• JPEG save + PC software: fast reporting and deeper analysis.

Smart & Connected

• Thermography App (iOS/Android): use your phone/tablet as a second screen, remote control, and to create/send reports on site.
• Bluetooth integration: pull live readings from testo 770-3 clamp meter and testo 605i hygrometer (optional) to enrich thermal images.
• ScaleAssist: auto scale setting for consistent, comparable building images.
• ε-Assist: auto emissivity and reflected temperature setup for correct results.

Applications

Preventive Maintenance

• Find electrical hot spots in boards, switchgear, PV strings.
• Check motors, bearings, and rotating plant for early faults.
• Reduce unplanned downtime and fire risk.

Building & Energy

• Locate thermal bridges, moisture risks, and air leaks.
• Verify insulation and window/door air-tightness.
• Use humidity mode with 605i to flag mould-risk areas (traffic-light view).

HVAC & Plumbing

• Balance systems, compare supply/return temps, trace underfloor loops.
• Pinpoint leaks and pipe ruptures with minimal opening.

Roofs & Envelopes

• Detect trapped moisture and damaged insulation in flat roofs.
