PC Building-Focused Callipers

The Thermal Grizzly TG Caliper is a compact digital measuring tool aimed at PC builders and modders, offering a 150 mm measuring range with metric and imperial readouts at a resolution of 0.1 mm and 0.01 in respectively. Constructed from high‑hardness, rust‑resistant ABS and rated IP54 for dust and splash resistance, the device features an LCD display, an ergonomic thumbwheel for controlled movement, and a zero function for comparative measurements. Its jaws and depth gauge enable verification of inner and outer tubing diameters, wall thickness, screw lengths, and thermal pad dimensions—tasks common in custom liquid‑cooling and component fitting.

Thermal Grizzly positions the TG Caliper as an affordable workshop accessory, noting practical guidance for accurate use: apply light, distributed pressure to avoid compressing soft materials, prefer the flat backs of the jaws for wider contact, and average multiple readings for consistency. The product listing highlights suitability for reconciling imperial and metric tubing standards and for routine checks during loop assembly and maintenance. Pricing at launch was listed at approximately $11.58 / €9.90, and purchasers are directed to official product materials for full specifications and warranty information.
