Product Description
United Testing Rockwell Hardness Tester, Tru-Blue II
Model: Tru-Blue II
The United Rockwell Hardness Tester Tru-Blue II is a state-of-the-art, computer-controlled digital hardness tester that utilizes a closed-loop load cell system for high precision and accuracy, meeting all NIST, ISO, CE, and ASTM requirements. It is known for its durability and ease of use in various industrial applications.
Key Features & Specifications:
- Operation: Computer-controlled testing with a digital closed-loop system for force application and an in-line depth measurement device.
- Hardness Scales: Capable of testing on 15 regular Rockwell scales (A, B, C, D, E, F, G, H, K, L, M, P, R, S, and V) and 15 superficial scales (15N, 30N, 45N, 15T, 30T, 45T, etc.).
- Load Forces: Regular loads include 60 kg, 100 kg, and 150 kg; superficial loads include 15 kg, 30 kg, and 45 kg.
- Display: Features a 4x20 bright vacuum fluorescent display with a resolution of points, tenths, and hundredths.
- Data & Statistics: Provides statistical summaries (average, range, standard deviation, high, low, number of tests), built-in ASTM E-140 conversion charts, and ASTM A-370 tensile strength values.
- Versatility: Includes settings for plastics dwell time per ASTM D-785 and automatic correction of hardness values for cylindrical parts. A removable parts clamp is also included to secure irregular or oversized parts.
- Portability: As it has no dead weights, pivot points, or knife edges to move out of adjustment, it can be moved to a new location without needing re-calibration.
- Connectivity: Equipped with RS-232 serial and parallel printer ports for data acquisition and printing, as well as a PS/2 keyboard connection for data entry.
