Extech Oyster Current and Voltage Calibrator

From Extech comes the precision "source" for calibrating process devices and measuring DC process signals from 0 to 24mA and 0 to 10V. Oyster applications include setup and calibration of process devices such as transducers, indicators, recorders and controllers, troubleshooting and field service, and product design.

Features:

• High accuracy 0.075%.
• Drives current loads to 350Ω.
• Oyster case with "flip-up" display is ideal for handheld or bench-top applications.
• Automatic shut-off when cover is closed.
• Large 3-1/2 digit display.
• Large LCD displays readings in mA (to 0.01mA) or as a percentage of the 0-24mA range (4-20mA = 0-100.0%) or as mV in voltage ranges.
• Complete with 9 volt battery and calibration cable with spade lug terminals (optional AC adapter).
• Dimensions: 3.8 x 4.2 x 1.8 inches(96 x 108 x 45mm) folded.
• Weight: 12 ounces (340 grams).

Applications:

• Setup and calibration of process devices such as transducers, indicators, recorders and controllers.
• Troubleshooting and field service.
• Product design.
