Rulers

Adhesive-Back Vertical Rulers

Permanently mount these rulers on machines, tanks, and walls to measure heights and depths.

Long-Length Vertical Rulers

Use to measure heights and tank levels.

Vertical Rulers

Measurements are printed from top to bottom for measuring heights and depths.

Long-Length Rulers

Create a ruler up to 192" long by adding continuous segments.

Tank-Level Measurers

Liquid-Level Tape Measures

Also known as oil-gauging tapes, use these tape measures to check the level of oil and other fluids in deep, large containers such as tanks and vats.

Adhesive-Back Tank-Level Rulers

Permanently mount these vertical rulers to walls and tanks.

Tank-Level Folding Rulers

Fold these vertical rulers for convenient storage and transport.

Long-Length Tank-Level Rulers

Connect continuous segments to create a ruler up to 10 ft. long.

55-Gallon Drum-Level Rulers

Measure volume in gallons without calculations.

Tank-Level Rulers

Built to resist corrosion and last in harsh environments, these vertical rulers are iron with a porcelain-enamel finish. Mount them to walls and tanks.

Tank-Level and Depth-Measuring Rope

Attach a plumb bob (sold separately) to the rope’s hook and lower it into your tank to take a measurement.

Depth Micrometers

Starrett Depth Micrometers with Calibration Certificate

These micrometers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Starrett Depth Micrometers

Measure the depth of holes, slots, shoulders, and projections by changing out the steel extension rods supplied in 1" incremental lengths.

Mitutoyo Depth Micrometers with Calibration Certificate

These micrometers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Mitutoyo Depth Micrometers

Use extension rods in 1" incremental lengths to measure the depth of holes, slots, shoulders, and projections.

Mitutoyo Electronic Depth Micrometers
with Calibration Certificate

These micrometers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Mitutoyo Electronic Depth Micrometers

Change out the steel extension rods supplied in 1" incremental lengths to measure the depth of holes, slots, shoulders, and projections.

Water-Resistant Economy Electronic Depth Micrometers

IP54 rated for limited protection from dust and splashing water.

Depth Gauges

Economy Depth Gauges

Take precise depth measurements in small holes and slots.

Starrett Depth Gauges

Reach deep into small holes and slots for precise depth measurements.

Harsh Environment Mitutoyo Electronic
Depth Gauges with Calibration Certificate

These gauges come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Harsh Environment Mitutoyo Electronic Depth Gauges

Measure depth in dusty or wet environments--these gauges are rated IP67 for protection from dust and temporary water submersion.

Mitutoyo Electronic Depth Gauges
with Calibration Certificate

These gauges come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Mitutoyo Electronic Depth Gauges

All gauges have zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the gauge is turned off.

Mitutoyo Electronic Depth Gauges with Extension Rods

Measure depths up to 8" using connectable extension rods.

Mitutoyo Electronic Depth Gauges with
Extension Rods with Calibration Certificate

These gauges come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Economy Electronic Depth Gauges with Extension Rods

Connectable extension rods allow you to measure depths.

Dial Depth Gauges

Check measurements at a glance.

Base Extensions for Mitutoyo Depth Gauges

Increase the base width of your depth gauge to measure large diameter holes.

Combination Squares

Starrett High-Accuracy Combination Squares

Replace your try square, miter square, depth gauge, height gauge, center-point finder, and level. The blade on these squares meets Fed. Spec. GGG-R-791H, which establishes uniform standards for accuracy, graduations, and size.

Starrett High-Accuracy Combination Square Heads

Attach to Starrett High-Accuracy Combination Square Blades with the included lockbolts.

Starrett High-Accuracy Combination Square Blades

Use these blades with Starrett High-Accuracy Combination Square Heads. They meet Fed. Spec. GGG-R-791H, which establishes uniform standards for accuracy, graduations, and size.

High-Accuracy Combination Squares

Use these squares in place of your try square, miter square, depth gauge, height gauge, center-point finder, and level.

High-Accuracy Combination Square Blades

Blades are for use with High-Accuracy Combination Square Heads.

High-Accuracy Combination Square Heads

Attach to High-Accuracy Combination Square Blades with the included lockbolts.

Combination Squares

Replace your try square, miter square, depth gauge, marking gauge, 90° level, ruler, and scriber with one tool.

Scribers with Base

Also known as surface gauges, use these to scribe lines, transfer measurements, or as height and depth gauges.

Tire Tread Gauges

Ensure tires are fit for use. Gauges measure tread depth up to 1".
