TOOLTOP ET11S Thermal Imager & Digital Multimeter, 24 × 32

Two measurement tools in one compact handheld

The TOOLTOP ET11S combines a basic thermal imager with a 4,000-count digital multimeter. Switch between viewing broad temperature patterns and taking supported electrical measurements, with a 2.8-inch resistive touchscreen and a built-in USB-rechargeable lithium battery.

Know its limits before you buy: The thermal sensor has just 24 × 32 pixels. The supplier specifies that it needs a large temperature difference for useful imaging and is intended for general temperature distribution, not complex inspection. For home-inspection work, treat this as a supplemental screening tool, not a replacement for a higher-resolution inspection camera or confirmation testing.

Practical features

• One-click switching between thermal imaging and multimeter modes.
• AC/DC voltage, resistance, capacitance, diode, continuity, and duty-cycle measurement functions.
• USB-C interface for charging and supplier-supported PC transfer of stored images and measurement records.
• Iron Red and Rainbow thermal palettes with adjustable emissivity from 0.10 to 0.99.
• Automatic screen-off and power-off functions.

Thermal imaging specifications

• Sensor: uncooled focal plane, 24 × 32 pixels
• Image capture frequency: 16 Hz

Electrical safety: No verified CAT safety rating or certification is provided in the supplied listing. The listed voltage limits are not a substitute for a safety category rating. Confirm the instrument and test-lead ratings in the manufacturer's manual before electrical use; do not assume suitability for live panels or mains testing.

Size, storage, and operating conditions

• Size: approximately 5.28 × 2.72 × 0.98 inches (134 × 69 × 25 mm), excluding packaging
• Supplier-listed device weight: approximately 4.41 oz (125 g), not packed shipping weight
• Internal storage: 3.5 MB; image format: BMP
• Operating environment: 32°F–122°F (0°C–50°C), below 85% RH, non-condensing
• Storage temperature: −4°F–140°F (−20°C–60°C)

Operation notes

Use a fingernail or a suitable stylus on the resistive touchscreen. Automatic detector calibration occurs about every 10 seconds and can briefly pause the image for approximately 1–2 seconds. Obtain compatible PC software from a verified manufacturer source before installing it.
