The KSC114 Spiral Contractometer is constructed to self-center on the stand and the stand is constructed to self-center over a 4,000 mm Pyrex beaker. The stand is required for helix calibration.
An X indicates necessary equipment and a question mark indicates optional depending on plating bath operating conditions. Spiral/ Helices without Teflon mask can be used for control purposes with 4-10 % error depending on the deposit throwing power. Nickel results are about 5% error using the new design Specialty Testing Spiral Contractometer.
For all deposits except chromium, the PN: HY3005 Power Supply with zero to 5 amp output is recommended. For chromium, a 0-10 amp Power Supply is recommended.
To determine the deposit plating time and amperage reference the Specialty Testing Spiral Contractometer Brochure. A typical test for Nickel is 2.9 amps at 30 ASF for 20 minutes and 40 Seconds for a target thickness of 500 microinches.
