[Non-Contact & Safe Voltage Tester] - Testing can be achieved without physical contact for its NCV Inductive Probe; Insulation operation ensures the safety of testing; In testing AC voltage, it can automatically detect the live wire or null wire; Intelligently identify Electric Field; In the vicinity of the voltage to be tested, the pen will give an alarming sound; Safety Compliance： CAT.III 1000V CAT.IV 600V； CE.

[Adjustable Sensitivity & Dual Range Testing] - Adjustable sensitivity makes its measurement more sensitive and flexible; The Voltage Tester Pen has the dual testing range, you can adjust the sensitivity according to your needs(12-1000V AC or 48-1000V AC); Automatic Recognition of Voltage Intensity; In using, the NVC sensor of the probe can automatically identify the voltage and display it on the LCD screen, simple and clear.

[High Definition LCD Screen & Low Battery Indicator] - When testing the voltage, the brightness bar on the screen will tell you the voltage intensity; The screen will light up in red or green to distinguish the Live/Null Wire; When the battery voltage drops to less than 2.5 V, the flashlight of LED display reminds you to replace the battery

JSP GOLD JEWELRY TESTING & APPRAISAL KIT

FUN, FAST, AND ACCURATE! DETERMINES THE KARAT OF GOLD JEWELRY IN SECONDS!

GTE 2''x 4'' JEWELRY TOUCHSTONE FOR SAFE TESTING THAT WON'T DAMAGE YOUR JEWELRY

It has 16 Cells capacity

There’s a PC Software that allows controlling each cell independently. You can set different cycle count, charge or discharge state, manual workflow, or automated.

The software uses a database to store the cell test data. It can display graphs of the entire charge and discharge cycle, cell internal resistance, and plotted data of each cell’s temperature during the process.

10K GOLD ACID TESTING KIT: Easily test the karat content of gold with 10k gold acid testing kit! The kit includes ONE, 0.5oz shatterproof plastic squeeze bottles and one gold testing stone; the testing solution is potent, effective and will see you through hundreds of tests

GOLD TESTING KIT METHOD: This gold testing method is best used on gold that is yet to be smelted, due to the harsh nature of the solution, that could potentially damage an already finished item; if testing fine jewelry or other gold items, be sure to choose an inconspicuous spot so as not to compromise the finished piece

HOW THE GOLD TESTING KIT WORKS: To test gold karat content, scratch the item onto the test stone leaving a visible deposit, then place a small drop of the acid over top of deposit; if the gold is the same karat or higher the acid will not affect the deposit; if the deposit is of a lower karat, the deposit will dissolve and eventually disappear; ensure gold testing stone has been thoroughly washed before completing any testing

SILVER TESTING KIT: Easily test the purity of silver with Silver Testing Acid Solution Kit with Testing Stone! The kit includes two, 0.5oz shatterproof plastic squeeze bottles and one testing stone; the testing solutions are potent, effective and will see you through hundreds of future tests!

SILVER TESTING KIT METHOD: This silver testing method is best used on silver that is yet to be smelted, due to the harsh nature of the solution that could potentially damage an already finished item; if testing fine jewelry, sterling silver items or other finished items, be sure to choose an inconspicuous spot so as not to compromise the finished piece

HOW THE SILVER TESTING KIT WORKS: To test silver purity, scratch the item on to test stone leaving visible deposit, then place a small drop of the acid over deposit; the purity of the silver is approximated depending on the color the solution turns when applied to deposit; if solution turns red that indicates high quality silver; if solution turns blue or green the sample may contain brass or copper; if sample deposit dissolves, or solution turns a dark brown, it may be a base metal

【LED DIGITAL DISPLAY, ACCURATE READING】The Power Circuit Probe Kit designed with LED digital voltage display for accurate volt readouts. Bidirectional current voltage testing mode, you can attach the alligator clamp either to negative or positive ground, red light indicates positive polarity and green light indicates negative polarity. Compared with LCD, LED lights are not affected by light brightness, and can be read accurately in daytime or dark areas.

【COMPUTER SAFE】Equipped with insulation protective cover，which can better grip the body and screws, insulation protection against electric shock. Circuit board with line protection function, safer and more burn-resistant.

【FLEXIBLE TO USE & CARRY】Extra long 96” PU spring wire increases flexibility, range, and freedom when testing. A sharp stainless steel probe with protective rubber tip can reach into tight places and pierce insulation. Compared to cable wires, coil spring wires are lighter and easier to carry. This does not need to take up too much space in your toolbox or any storage area, it is convenient to use anytime, anywhere.
