Product details

Sort small electronic parts with a tool that holds the contact and reading together. The FNIRSI LCR-ST2 component tweezers measure resistance, capacitance, inductance and ESR, with five test frequencies from 100Hz to 100kHz. A 1.47-inch display and USB-C charging suit a compact bench; this Standard kit does not include Kelvin clips.

Make contact without the extra juggling.

The tweezer format lets you place the tips across a suitable component while the display sits just above your hand. It is a useful arrangement for sorting small parts or checking a value during bench work. Good contact and a properly isolated component remain essential to a useful reading.

Tweezer tips contacting a small electronic component

Keep the bench tool compact.

The 1.47-inch display and rotating reading orientation help keep results visible as you handle the tweezers. A rechargeable 300mAh battery and USB-C charging suit a small electronics workspace. Put it beside the parts tray, ready for the next unidentified component.

Rotating display orientation for either hand

In the box

FNIRSI LCR-ST2 Standard tweezer meter with standard tips and charging cable. The separate Kelvin clip accessory shown with Plus packages is not included.

This is an excellent product, but the way the two variants (with and without kelvin clips) are presented is very misleading and invites ordering mistakes. When you select 'set 1' which is without the clips and is the default, the item heading still mentions 'kelvin clip' and many of the pictures show them. Remember to select 'set 2' and later refresh the page, it defaults back to 'set 1' and looks like you just got a nice price reduction! It is really not worth considering 'set 1' since the price difference is small and the custom connector means there is no way of getting compatible clips later. The clips are a unique benefit of this model over other lcr tweezers and enable comfortable measurement of through-hole components and the resistance of cables. The store did however handle my mistake very well allowing me to return the original for credit and reorder the intended version.

Questions before you buy

Can I measure a powered circuit?

No. Use it on isolated, discharged components and follow the manual. Power or residual capacitor charge can damage the meter and create a hazard.

Will an in-circuit reading always be correct?

No. Other connected components can affect the reading. Isolate the component as required for a meaningful measurement.

Is this the kit with Kelvin clips?

No. This is the Standard tweezer package. Choose measurements that the supplied tweezer contacts are designed to make.

How do I choose the correct option?

Use the option buttons above the Add to cart button and check the selected name, image, price, and availability before ordering. Choose only the option that matches the version you want.

How long does shipping take?

Standard shipping is free on every order, with no minimum spend. Delivery estimates and optional express rates are shown at checkout. View shipping policy.
