Diamond Tester with Scale and Loupe

The HMKIS kit combines a diamond tester pen, a 200g capacity pocket scale with 0.01g readability, and a jeweller’s loupe offering 30X, 60X and 90X magnification. It is intended for jewellers, gemstone buyers and hobbyists who need to verify diamond authenticity and weigh small items in one portable set.

Power and Environment Needs

The tester runs from a Type-C connection or a 9V supply; the manufacturer notes the Type-C option is recommended for best results and that the unit is not rechargeable. Operation must occur between 50 and 95°F in a windless setting, and the scale measures 5.2 by 2.99 by 0.79 inch for bench or field use.

Thermals, Noise and Power Draw

Continuous testing of small diamonds requires pauses so the probe can cool down. Incorrect contact on metal or skin triggers a flashing indicator or automatic shut-off. The device distinguishes diamond from simulants such as glass or cubic zirconia but cannot separate moissanite from natural diamond.

Questions about this item

What is the operating temperature range for the HMKIS diamond tester?

The HMKIS diamond tester needs to be within the range of 50 to 95°F and used in a windless environment for accurate testing.

How loud is the diamond tester during continuous daily use?

The diamond tester emits a sound when the Level Meter reaches 9 lights during testing, but no specific noise level or decibel rating is provided for all-day operation.

What power source must I already have to run the tester?

The tester requires either a Type-C USB power cable or a 9V battery; it is non-rechargeable so one of these must be supplied by the user.
