The R320 instrument provides ZERO, TARE and OPTIONAL PEAK HOLD functionality as well as more setup options (eg. serial and setpoints) and printing functionality.
It also supports special functions (eg. peak-hold, averaging, counting, etc.), via the user definable key. It is equipped with an NVRAM store to ensure day-to-day operating settings (eg. ZERO, TARE, CLOCK, etc.), are retained when power is removed.

This instrument has two isolated transistor outputs with status display on the front panel as well as the RS-232 communications port that can be used for printer driving or connection to a remote display or PC. There is a built-in clock for date-stamping printed outputs.
We also offer the R320-K344, an economical version with all functions except the peak-hold circuit.
