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.
