Electrical Test Equipment Rental & Sales

Which electrical instruments can you rent?

We also sell electrical test equipment, so you can ask for rental and purchase prices and compare them over your project.

Electrical instrument types we calibrate most often

Techmaster has completed 56,750 electrical calibrations in the last ten years across 7,039 instrument lines. These are the types we handle most:

Electrical rental: what to check when it arrives

• Check a multimeter's input fuses before using the current ranges. A blown fuse reads zero current rather than showing an error.
• Size a DC power supply or electronic load at your operating point, not just its maximum voltage and current. Power is usually the limit.
• Use remote sense leads on a power supply at high current, so the drop in the load leads does not lower the voltage at your device.
• Set a hipot tester's test voltage, trip current and ramp time to your test standard before connecting the device under test.

What calibration comes with the rental?

Every rental ships with a current calibration certificate from a Techmaster laboratory. Check that its due date covers your last day of testing and that it covers the ranges you will use.

DC and low-frequency electrical calibration (DC voltage to 1.1 kV, current to 1,000 A via shunts, clamp-on current to 1,025 A) is on the ANAB scope at all four accredited labs. High voltage is accredited to 100 kV at Vista and 150 kV at San Antonio, high resistance to 10 PΩ at San Antonio only, and AC high current to 1,500 A at Orlando and San Antonio. Exact ranges and uncertainties are on our published accreditation scope.
