Portable Electronic Balances
The OHAUS SPJ Balances – The Best Value in Portable Jewelry Balances!
Designed for use in general weighing of precious metals and jewelry, the OHAUS SPJ Carat and Gold
balances feature easy-to-use two-button operation, a high-contrast LCD display, multiple weighing units,
four application modes, and the option of either RS232 or USB connectivity. The SPJ is the portable balance
for your needs!
• Maximum Protection – The SPJ is designed with mechanical and software protection against shock
and overloading which can cause damage to the weighing cell. An integrated shipping lock protects
the weighing cell during transportation or storage.
• RS232 or USB Connectivity – Interface accessories are easy to install at anytime, even after purchase.
The data cable is integrated in the kit, eliminating the need for additional cables.
• Multiple Application Modes – The SPJ features Enhanced Parts Counting, Percent Weighing,
Totalization and Display Hold.
• Multiple Weighing Units – The SPJ weighs in grams, carats, ounces, troy ounces, pennyweights and
grains. Other units available include tolas, ticals and 3 tael units. The SPJ6001 can also weigh in kg
or lb for even heavier items.
SPJ Carat and Gold Portable Electronic Balances
Built-In Application Modes:
Parts Counting – The SPJ is designed for counting parts for inventory control, parts
bagging, receiving, dispensing and ticket counting.
• Select from a sample size of 5, 10, 20 or 50 pieces while in counting mode with
a quick button press.
• The SPJ features user-enabled automatic recalculation of the average piece
weight – instead of counting 100 parts for a sample, count 10 and let the
SPJ count the rest of the sample! For applications where automatic recalculation is not desired, the easy-to-use menu system allows this feature to be
disabled.
• The SPJ can also be configured for situations where only the counting feature is required.
Percent Weighing – Use the Percent Weighing mode to compare samples for compounding, formulation, or quick weight
checking. Place your reference weight on the platform, enter the weight into memory, and the display will show the
percentage of the sample weight on the platform compared to the reference weight.
Totalization – Use the SPJ’s memory function to repeatedly sum the weight on the platform for compounding and
formulation. Unlike other balances, the SPJ allows totalization up to the limit of the display!
Display Hold – The Display Hold mode allows you to retain the weight of an over-sized package on the SPJ’s display.
Great for postal and shipping applications!
