Built for rugged industrial environments, this handheld digital loop calibrator features an IP65 enclosure rating, meaning it is dust-tight and waterproof, suitable for harsh plant conditions. DC voltage, DC current can be measured, internal 24V loop-powered. Its portability makes it convenient for on-site diagnostics and maintenance.
3.2 Inch TFT Color Display
- TFT color display offers higher resolution than ordinary LCD screen, providing clearer, sharper readings. Users can easily view complex data, reducing the likelihood of misreading values, which is critical in calibration tasks.
- TFT display is robust and can withstand industrial environments. It is less prone to damage from vibrations or impacts. Additionally, TFT often consume less power, which extends the life of the handheld loop calibrator.
- Unlike conventional display, TFT screen offers wide viewing angles without color distortion or contrast loss.
ABS Shell & IP65 Protection Level
- Compared with metal material, ABS is significantly lighter. A loop calibrator with an ABS shell is easier to carry, especially for technicians who need to perform on-site calibration for long periods.
- ABS material has excellent toughness and impact resistance. In real-world calibration work, a loop calibrator is often used in demanding environments. Accidental drops, knocks, or vibrations are common. ABS shell can effectively absorb shocks and reduce damage to internal electronic components.
- The sealed enclosure required for IP65 protection also improves mechanical strength. The instrument is better protected against accidental splashes, dirt, and daily wear during transport and on-site use. Components are shielded from corrosion, contamination, and moisture damage.

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 temperature range can this handheld loop calibrator operate in?
This handheld loop calibrator is designed to operate reliably within a temperature range of 0β to 50Β°C. For optimal performance and to ensure the longevity of the device, it is recommended to use it in moderate conditions, ideally between 10β and 40β. Avoid exposing the calibrator to extreme heat or cold, as operating near the upper or lower limits of its range may affect measurement accuracy or cause potential damage.
