Low-Cost Digital Multimeter with ±0.025% DCV Accuracy and Basic Measurement Capabilities for General Bench Testing

Hioki benchtop digital multimeters are high precision 5-1/2 digit meters that sample 300 times/second. The 3237 Series is the basic economy model, and comes with a comparator function that is especially useful for production lines.

Key Features • Simple function and basic model • High-speed 3.3msec comparator for production line use • Comparator function with open-collector output, beep sound, or LED display • Built in RS-232C interface and External control I/O, or added GP-IB interface (-01 model)

Basic specifications (Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year) *Basic accuracy is when sampling rate is “Slow”.* Regarding DMM accuracy: Due to the many ranges and functions available in a DMM, only the basic accuracy is indicated for reference. Please refer to the individual catalogs for detailed accuracy information.
