A portable loop calibrator is a compact, handheld instrument used to test, calibrate, and troubleshoot process control loops in industrial systems. It typically features a digital display, allowing precise readings. Equipped with automatic step and ramp functions, its 25% step feature enables rapid linearity testing.
Large Screen & Backlit Display
- A large screen display significantly improves readability, especially in challenging work environments. Technicians can easily read measurements at a glance.
- Press the button to turn on the backlight. A portable digital loop calibrator equipped with backlit offers clear advantages in real-world fieldwork. The backlit buttons improve visibility in low-light environments such as control rooms, outdoor sites, or nighttime maintenance.
Equipped with Built-in Bracket
- The built-in bracket allows the process loop calibrator to be positioned on a flat surface, or a panel without needing an operator to hold it continuously. This frees up hands to make adjustments, or record readings, reducing fatigue during long calibration tasks.
- Unlike separate stands or supports, the built-in bracket adds minimal weight or bulk, retaining the portability of the device. Technicians can carry the calibrator easily between sites without extra accessories.

Q1: What is a loop calibrator?
A1: A loop calibrator is a precision instrument. It can measure DC voltage, DC current and loop current. It is portable, often handheld, and designed for field use, making it essential tools for maintaining reliable industrial systems.
Q2: What industries commonly use loop calibrator?
A2: Loop calibrator is widely used across industries that rely on precise process control and instrumentation. Common sectors include oil and gas, chemical and petrochemical plants, power generation, water and wastewater treatment, and pharmaceutical manufacturing.
Q3: How to maintain a digital loop calibrator?
A3: Always store it in a clean, dry, and temperature-controlled environment to prevent moisture or dust damage. Regularly check the battery and replace it when low to avoid measurement errors. Clean the device and test leads with a soft, dry cloth; avoid solvents that may damage components.
Tips: What is the difference between a loop calibrator and a multimeter?
A loop calibrator and a multimeter serve different purposes. A loop calibrator is primarily used in process control to simulate, measure, and calibrate current loops, ensuring instruments like transmitters and controllers function correctly. A multimeter, on the other hand, is a general-purpose tool that measures voltage, current, and resistance in electrical circuits but does not simulate signals or calibrate process loops. They complement each other in industrial settings.
