⚡ Electroplating Industry — Ampere Hour Meters

Countronics programmable ampere hour meters are the instrument of choice for electroplating operations across India — for gold, silver, chrome, nickel, copper, tin, and all other electroplating processes where consistent plating thickness is critical.

Quick Answer: Electroplating operations use programmable ampere hour meters to control plating thickness by measuring total electrical charge rather than time, ensuring consistent gold, chrome, nickel, and other metal coating thickness across every batch.

Why Plating Thickness Depends on Ampere Hours — Not Time

A common misconception in electroplating is that plating time alone determines thickness. In reality, plating thickness is directly proportional to the total electrical charge passed through the bath — measured in ampere-hours (AH). If the rectifier voltage or bath resistance fluctuates, the current changes, and the same time period produces different thicknesses in different batches.

By measuring and controlling the total AH rather than time, the plating operator ensures that every batch receives exactly the same amount of electrical charge — and therefore exactly the same plating thickness — regardless of what happened to the voltage or current during the cycle. This is why every serious electroplating operation uses an ampere hour meter, not just a timer.

Key Features for Electroplating

  • Programmable relay cutoff — power cuts automatically when preset AH is reached
  • Shunt calibration — programmable for any shunt up to 9999A for 75mV
  • EEPROM memory — AH count retained during power failures
  • AH or AMin selectable — choose the unit appropriate for your bath
  • Rear calibration lock — prevents tampering with calibration settings
  • 6-digit totaliser — cumulative AH tracking across multiple batches

Electroplating Applications

Frequently Asked Questions

How does an AH meter control plating thickness?

Plating thickness is proportional to total charge (ampere-hours) — not time. By presetting the target AH and using the relay to cut power when reached, the AH meter ensures consistent thickness in every batch regardless of voltage or current fluctuations.

Which AH meter is best for gold plating?

For gold plating, the 810AH or 805AH with programmable relay cutoff are recommended. The precise AH control ensures consistent gold thickness — critical for precious metal plating where over-plating wastes expensive material and under-plating fails quality standards.

Does data remain during power failure?

Yes. Countronics AH meters use EEPROM memory to retain accumulated AH count and all settings during power failures. The instrument continues from where it left off when power is restored.

What shunt is needed?

Any standard 75mV DC shunt. The calibration factor is programmable for any current rating up to 9999A. Shunts are purchased separately based on your bath current rating.

Can these meters be used for chrome plating?

Yes. Countronics AH meters are used for all electroplating types including chrome, hard chrome, decorative chrome, nickel, gold, silver, copper, zinc, and tin plating. The programmable shunt calibration makes them universal.
