Anritsu ACSII Series Surface and Internal Temperature Calibrators
The Anritsu ACSII Series provides controlled temperature sources for checking and calibrating contact temperature probes. Choose a surface model for contact-head probes, an internal model for insertion probes, or a combined system for both tasks.
A suitable calibration setup helps you compare measurements at repeatable temperature points. Select the system according to your probe geometry, required range and calibration procedure.
Key Features
- Four models covering surface, internal or combined calibration.
- 30 to 300°C range for ACSII-1000; 30 to 500°C for the other models.
- PID control with automatic tuning.
- Separate control and calibration units.
- Internal calibration models with eight holes made to specified dimensions.

- Instruction manual and test report.
- ACSII-1000 / ACSII-2000: protective calibration-block cover.
- ACSII-3000 / ACSII-4000: Pt100 standard calibration sensor.
Selecting the Right Calibration Setup
- Surface probes: check head size, shape and the contact method on the calibration surface.
- Insertion probes: provide shaft diameters and usable insertion lengths so the hole arrangement can be specified.
- Temperature points: choose points relevant to your normal measurements and acceptance limits.
- Workspace: allow adequate bench capacity and room for the separate controller and calibration unit.
- Documentation: specify the reference calibration, traceability and reporting required by your quality procedure.
A supplied test report does not by itself establish an accredited calibration service. Agree the required documentation and measurement uncertainty before ordering.
