Preciva LF326 Digital Caliper, Rechargeable Stainless Steel, IP54, 150 mm

Rechargeable power and a stainless steel body make the Preciva LF326 Digital Caliper ready for repeat measuring tasks without relying on frequent battery replacements. Its 0–6-inch/150 mm range, large LCD and one-button unit conversion help keep measurements easy to read and quick to compare at the bench.

It measures internal and external dimensions, depth and step levels, so one tool can support a range of workshop jobs.

Key takeaways

The LF326 combines a stainless steel construction with a Type-C rechargeable battery and an IP54 protection rating. A full charge takes 50 minutes, and the display switches off automatically after five minutes of inactivity to help conserve power. The large LCD presents readings clearly, while one-button conversion lets you move between decimal inches, fractional inches and millimetres as a job requires.

For controlled measurements, a smooth-gliding thumb roller and locking screw help steady the caliper in position. Its stated accuracy is ±0.001 inch (0.03 mm), with a resolution of 0.0005 inch (0.01 mm). The zero-setting function supports differential measurements from any position, useful when comparing a feature against a chosen reference rather than starting from zero.

The four measurement functions make the tool practical across machining, woodworking and mechanical work. For example, when checking a part for fit, you can measure an outer dimension, check an internal opening, then use the depth rod or step faces for other dimensions without switching to a separate measuring tool.

Practical tips

Choose the measurement mode that matches the feature: the jaws handle internal and external dimensions, while the depth rod and step faces cover depth and step measurements. Set the display to the unit used on your drawing or project, and use the zero function when you need a relative measurement. The locking screw helps hold a reading while you compare it with a part or reference.

Compared with choosing separate tools for different dimension types, this caliper brings four functions into one instrument. It suits a workbench where jobs move between sizing components, checking openings and measuring depth. The rechargeable design is also a practical fit for regular measuring tasks, with Type-C charging instead of routine battery replacement.

Who it’s for

This model is suited to machinists, jewellers, woodworkers and automotive technicians who need a digital instrument for everyday dimensional checks. The 0–6-inch/150 mm range and multiple measurement functions make it useful for varied small-part work, while the selectable inch and metric formats help when projects or reference measurements use different units. Its large LCD is especially helpful when you want to read a result directly at the workpiece.

Buyer feedback often highlights the caliper’s quality, functionality and value. Impressions are more varied on battery life, accuracy and reliability, so the practical appeal is its feature set and straightforward measuring workflow rather than a promise that every user will have the same experience.

Buying verdict

The Preciva LF326 brings rechargeable convenience, stainless steel construction and four measurement functions together in a 150 mm digital caliper. For workshop users who regularly check internal, external, depth and step dimensions, its LCD, unit conversion and zero-setting function make it a versatile tool for keeping measurements clear and consistent across different tasks.
