NM03AH4000

The Chino AH4000 24-Point Recorder is a versatile and reliable instrument for monitoring and recording data from up to 24 input channels. This particular unit is offered without a case and without a pre-wired thermocouple (T/C) jack panel, providing flexibility for users who may have existing mounting solutions or prefer to customize their input connections.  

The AH4000 series is known for its clear digital display and simultaneous analog bar graph display, allowing for easy visualization of multiple data points at a glance. It supports various input types, including thermocouples, RTDs (Resistance Temperature Detectors), and DC voltage/current (when used with external shunt resistors, sold separately). Each channel's range and input type can be individually programmed, offering significant adaptability for diverse monitoring applications.  

Despite the absence of a pre-wired T/C jack panel, the recorder is designed for straightforward wiring to accommodate your specific sensor connections. Its robust design and user-friendly front keypad facilitate easy configuration of measuring and recording settings.
