Digital Calliper INSTAR 349-103 0–300 mm IP54 Stainless Steel 4Cr13 Resolution 0.01 mm LCD Display For Workshop and Manufacturing
You already have the maximum available quantity in your cart.
The digital calliper INSTAR 349-103 is designed for precise measurements in the workshop, in engineering production, in locksmithing, and during machine and equipment maintenance. The measuring range of 0–300 mm accommodates long profiles, plates, large flanges, and substantial workpieces that shorter measuring tools cannot handle. The electronics are protected with an IP54 rating, safeguarding it against dust and splashing water during regular workshop use. The measured value is displayed on a large LCD screen with a resolution of 0.01 mm. The jaws and ruler are made from stainless steel, which resists wear and corrosion.
The electronic casing has a rounded shape with a relief marking of IP54 and fits comfortably in the hand. Above the display is a mm/in button for switching between millimetres and inches, and below the display are the OFF/ON and ZERO buttons for powering on, off, and zeroing at any position. With the zeroing function, you can reset the display on a reference part and directly read the differences in dimensions. The set position of the jaws is secured by a locking screw on the top of the casing, allowing you to transfer the measurement to the workpiece. The fine adjustment of the jaws is ensured by a knurled wheel operated by your thumb. The ruler is made from stainless steel 4Cr13, and its surface features a readable scale for quick reference checks.

After use, wipe the calliper clean of dust, chips, and grease, and store it in a dry place. The IP54 rating protects the electronics from dust and splashing water, but do not submerge the calliper in water or coolant. Protect the measuring surfaces of the jaws from impacts and do not use the calliper as a scribing needle or lever. For prolonged storage, it is advisable to remove the battery to prevent discharge or damage to the contacts. Before each measurement, it is good practice to close the jaws and check that the display reads zero.
INSTAR 349-103 is a practical assistant for machinists, locksmiths, carpenters, modellers, and DIY enthusiasts who need to measure large parts with a resolution of hundredths of a millimetre. Its stainless construction, protection against dust and splashing water, and switching between millimetres and inches make it a versatile tool for any workshop. The 300 mm range covers even large workpieces, and the calliper can handle external dimensions, internal diameters, and the depth of grooves and holes. You can read the value directly from the LCD display without the need to interpret a vernier scale.
