Hioki 3238 Digital HiTester

The Hioki 3238 Digital HiTester has been discontinued. See Hioki DM7275 Precision DC Voltmeter or the Hioki RM3544 Resistance Meter.

The Hioki 3238 Digital HiTester is a multi-functional digital multimeter designed for high precision bench testing with ±0.01% DCV accuracy. Its high-speed 3.3 msec comparator function, open-collector output, beep sound or LED display make it particularly useful for production lines. The built-in RS-232C interface and External control I/O, or added GP-IB interface (-01 model) provide additional connectivity options. CAT II 300 V rating ensures safety during testing.
