EXTECH

EXTECH is a brand of test and measurement instruments used in electrical, HVAC, environmental, and industrial maintenance applications. The product line includes handheld multimeters, clamp meters, voltage testers, infrared thermometers, data loggers, borescopes, and pH measurement accessories. Many EXTECH instruments are designed for field use, with IP ratings such as IP64 and IP67 on selected models, indicating resistance to dust and water ingress. Measurement ranges vary by model; for example, the VT30 voltage and continuity tester covers 0 V to 690 V AC/DC with a continuity threshold of 200 kΩ. The HDV700 Series borescopes support interchangeable camera probes with resolutions of 640 x 480 or 1280 x 720 pixels and shaft lengths from 3 1/4 ft to 98 3/8 ft, enabling remote visual inspection of pipes, ducts, and machinery. EXTECH also supplies pH buffers in liquid and tablet form, color-coded for pH 4.00 (red) and pH 7.00 (green), used to calibrate pH meters and electrodes. 3G Electric stocks over 380 EXTECH SKUs and supports global procurement of these instruments and accessories. The catalog includes individual instruments, kits such as the EX505A-K digital multimeter and volt detector kit, and replacement probes and camera heads for borescope systems. Technical buyers can source EXTECH products through 3G Electric with logistics coordinated from Singapore to international destinations. The brand's instruments are commonly specified where portable, battery-operated test equipment is required for troubleshooting, commissioning, and preventive maintenance. 3G Electric provides access to the EXTECH range without regional restrictions, serving plant engineers, maintenance managers, and procurement specialists who need documented specifications and consistent part numbers. For teams standardizing on EXTECH, 3G Electric can supply both primary instruments and the associated accessories, such as pH buffers, test leads, and camera probes, from a single source. The product data available includes manufacturer part numbers, UNSPSC codes, and key specifications to support requisition and inventory planning. This allows buyers to match existing EXTECH tools or introduce new ones with confidence in compatibility and performance ratings. 3G Electric does not manufacture EXTECH products; it distributes the brand as part of its industrial equipment portfolio. All specifications referenced are as provided by the manufacturer or publicly available product documentation. For current pricing, lead times, and availability, contact 3G Electric with the specific EXTECH model or SKU.

Frequently asked questions

Common questions about EXTECH from 3G Electric.

What types of EXTECH multimeters and testers does 3G Electric supply?

3G Electric supplies a range of EXTECH multimeters, clamp meters, and voltage testers. Examples include the EX505A-K kit, which combines a 4,000-count digital multimeter with a volt detector, and the VT30 digital voltage and continuity tester rated for 0 V to 690 V AC/DC with a continuity threshold of 200 kΩ. Selected models carry IP ratings such as IP64 or IP67 for dust and water resistance. Availability varies by model; contact 3G Electric with the specific EXTECH part number for current stock and lead time.

Are EXTECH HDV700 Series borescope probes interchangeable?

Yes, the EXTECH HDV700 Series borescopes accept interchangeable camera probes. Available probes include models with 640 x 480 or 1280 x 720 pixel resolution and shaft lengths from 3 1/4 ft to 98 3/8 ft. Some probes include an integrated handset or a spool for cable management. When ordering, confirm the probe model number (e.g., HDV7C-A4-60-3, HDV7C-49-DUAL-1, HDV7C-55-3, HDV7C-P28-30) to ensure compatibility with your existing HDV700 series base unit.

What pH buffer solutions does EXTECH offer for calibration?

EXTECH provides pH buffer solutions in liquid and tablet form. The liquid pH 4.00 buffer is color-coded red and supplied in a 1 pt plastic bottle (model PH4-P). The pH 7.00 buffer is available as tablets that dissolve in distilled water to prepare 1 pt of solution; these are color-coded green (model PH7-P). Both are lab-grade and used for calibrating pH meters and electrodes. 3G Electric stocks these buffers along with other EXTECH pH accessories.

What is the IP rating of EXTECH voltage testers and multimeters?

IP ratings vary by EXTECH model. The VT30 voltage and continuity tester has an IP64 rating, which indicates protection against dust and water splashes. The EX505A-K kit includes a digital multimeter rated IP67, meaning it is dust-tight and protected against temporary immersion in water. These ratings apply to the specific models mentioned; always check the individual product specifications for the exact IP rating of a given EXTECH instrument.

Can 3G Electric supply EXTECH instruments outside of Singapore?

Yes, 3G Electric ships globally. While headquartered in Singapore, the company supports international procurement of EXTECH test and measurement instruments. Orders can be shipped to destinations worldwide, with logistics coordinated based on the buyer's location and requirements. For export inquiries, provide the EXTECH model numbers and quantities needed, and 3G Electric will confirm shipping options and documentation.

Does 3G Electric stock EXTECH accessories such as camera probes and test leads?

3G Electric stocks a range of EXTECH accessories, including borescope camera probes for the HDV700 Series, pH buffers, and items included in instrument kits. Accessories are listed with manufacturer part numbers and compatibility details. If you need a specific EXTECH accessory not shown in the catalog, contact 3G Electric with the part number; availability can be checked against the broader EXTECH line.
