Hioki 3239 Digital HiTester
The Hioki 3239 Digital HiTester has been discontinued, See Hioki DM7275 Precision DC Voltmeter or the Hioki RM3544 Resistance Meter.
The DIGITAL HiTESTER 3239 is a high-precision digital multimeter designed for bench testing. It boasts a DC voltage accuracy of ±0.01%, making it ideal for applications that require extremely precise measurements. The 3239 Series utilizes a 4-terminal resistance measurement method and samples 300 times per second, providing fast and reliable results.
One of the key features of the DIGITAL HiTESTER 3239 is its high-speed 3.3 millisecond comparator, which is especially useful for production lines. The comparator function comes with an open-collector output, beep sound, or LED display, allowing users to choose the most appropriate mode for their needs. The DIGITAL HiTESTER 3239 also has a built-in RS-232C interface and External control I/O, or users can opt for the GP-IB interface (-01 model) for added versatility.
With a CAT II 300V safety rating, the DIGITAL HiTESTER 3239 is a reliable and safe choice for high precision bench testing. Whether you’re working in a production line or conducting research in a laboratory, the DIGITAL HiTESTER 3239 is a versatile and powerful tool for accurate measurements.
