Digital Calliper INSTAR 146-303 0–300 mm IP67 Rated Coolant Resistant Resolution 0.01 mm Stainless Steel For Workshop and Manufacturing
You already have the maximum available quantity in your cart.
The digital calliper INSTAR 146-303 is designed for precise measurements in the workshop, in engineering production, and during machine maintenance. The measuring range of 0–300 mm can handle long profiles, large flanges, plates, and sizeable workpieces that shorter measuring tools cannot accommodate. The electronics are protected with an IP67 rating, meaning the calliper withstands dust, water, and coolant used with machine tools. The measured value is displayed on a clear LCD screen with a resolution of 0.01 mm. Both the body and the rule are made of stainless steel, which is highly resistant to wear and corrosion. The scale on the rule also allows for quick reference checks of the jaw position without needing to look at the display.
Model 146 features a square electronics housing with an IP67 rating and a knurled wheel for fine adjustment of the jaw with your thumb. Control is managed by two buttons, MM/IN and O/ON, which switch the units between millimetres and inches, reset the reading, and select absolute and incremental measurements. In incremental mode, you can reset the display at any jaw position and measure differences against a reference part. The set position is secured by a locking screw on the top of the housing, allowing you to transfer the measurement to the workpiece. The manufacturer states the repeatability of measurements is 0.01 mm, ensuring that repeated measurements of the same part yield consistent results.

After use, simply wipe the calliper clean of dirt and coolant residue and store it in a dry place. Protect the measuring surfaces of the jaws from impacts and do not use the calliper as a marking needle or lever. Power is provided by a CR2032 lithium cell, which should be inserted into the battery compartment in the electronics housing during replacement. The rule is stamped with a serial number, allowing you to easily distinguish the calliper from others in the workshop. For prolonged storage, it is advisable to remove the battery to prevent it from discharging or damaging the contacts. Before each measurement, it is good practice to close the jaws and check that the display shows zero.
INSTAR 146-303 is a reliable assistant for anyone needing to measure quickly, clearly, and with a resolution of hundredths of a millimetre. The combination of stainless construction, waterproof protection, and switching between millimetres and inches makes it a versatile tool for machinists, locksmiths, modellers, and DIY enthusiasts. The 300 mm range accommodates large parts and long profiles, and the calliper can measure external dimensions, internal diameters, and the depth of grooves and holes. Thanks to its resistance to coolant, you can use it directly at the lathe or milling machine.
