More Information

Features:

6 DC Current Ranges
4 AC Current Ranges
Photodetector

The Model 840-C is a powerful handheld dual-microprocessor based optical power measuring instrument. It makes sensitive DC or AC Peak-to-Peak optical power measurements with the convenience of full spectrum sensor calibration, quick sensor change, and a host of user-friendly features.

The Model 840-C operates with's line of optical detectors through the use of an in-line calibration module. This Cal Module supplies calibration and detector information while still allowing the detector to be detached and used with other equipment in the lab. For use in fiber optic applications, a combined detectorcalibration module provides connectorized input at the meter (Model 818-F Series modules).

The Model 840-C has been designed with the most frequently used keys placed within natural reach. A backlit 4-digit liquid crystal display (LCD) permits easy reading in darkened areas. An audio indicator allows the user to maximize a signal without having to look at the display. The analog output allows other instrumentation to monitor the Model 840-C power readings by providing a voltage output proportional to detector current. The Model 840-C's ultra low noise, thermally stable, transimpedance input amplifier optimizes the detector sensitivity and linearity.

The 840-C MKS Instruments Handheld Optical Power Meter may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).

	Amelia C. Have dealt with Artisan for over a decade and have always found them to be knowledgeable, professional and have a great inventory to choose from! Great company!
	Neo Contacted Artisan for hard to find that has been out of circulation for nearly a decade. Their rapid response and availability exceeded all other suppliers. They supplied the part overnight to an out of state facility which allowed us to repair our equipment successfully. Well packed electronics. Well stated and professional documentation. I work with a hundred different suppliers any day of the week in my profession. Artisan remains at the very top of the bookmark tab. Thanks so much.
