The PD691 Universal mV Meter accepts all the standard strain gauge and load cell signals: 0-30 mV, 0-200 mV, +/-15 mV and +/-100 mV and displays these signals in engineering units on a 4-1/2 digit display. The display also includes an extra zero which may be used to handle numbers up to +/-199,990. Standard features include field selectable 5, 10 or 24 VDC excitation power supply, peak hold, capture or programmable tare, and more.

 Precision Digital's new Universal Rate/Totalizer Batch Controllers may be used to display rate and total as well as provide simple automatic or manual batch control. Models are available for analog inputs such as 4-20 mA or frequency/pulse inputs such as pulse, open collector or switch closures. These meters feature a full six digit display, programmable time base of second, minute and hour, as well as a user programmable multiplier out to five decimal points. They also provide 24 VDC excitation for analog inputs and up to 50 mA for frequency/pulse inputs.
