Model 804AH

Ampere-Hour Meter with dual time relays

Features

This micro-controller based programmable Amp-Hour Meter is designed to integrate and display DC current flowing respect to time. It becomes a measure of the total current energy.
It allows user calibration for any shunt up to 9999 Amps for 75mV
It can be used for Ampere-Hours or Ampere-minutes. The meter has separate displays for current and ampere-hours/mins.
The Cumulative Ampere-Hour is stored on power failure. A settable limit for Ampere-Hours with dual time relays makes the instrument ideal for repeated accurate dosing cycles.
Rear calibration lock to prevent tampering with settings and an aesthetically designed front panel with membrane switches complements the system.
