Features:

The Model 287 is an all-in-one handheld charge plate monitor designed for periodic verification of ionization equipment. It combines measurement, data storage, and environmental monitoring in a compact, easy-to-use device controlled by four pushbuttons.
• Measures and displays voltage, decay time, temperature, and humidity in one unit
• Stores results for up to 10 manual tests and 10 automatic test sequences
• Simple four-button interface for quick and efficient operation
• Built-in high voltage generator charges plate above 1050V for decay testing
• Balance mode displays isolated plate voltage and peak measurements
• Real-time environmental monitoring with data logging
• Microprocessor-driven system for reliable and consistent operation
• Built-in self-test functions including battery and system diagnostics
