The MECO 333P+ Multifunction Process Calibrator is an advanced portable calibration solution developed for engineers and technicians involved in industrial automation, instrumentation, and process control systems. It combines multiple signal generation and measurement functions in a single compact device, reducing the need for multiple calibration instruments.
The instrument is capable of measuring and generating DC voltage signals, DC current signals, thermocouple signals, resistance, and RTD (PT100) inputs, making it suitable for calibration and troubleshooting of various industrial field devices. It supports commonly used process signals such as 4–20 mA current loops, voltage ranges, and temperature sensor signals including K, E, J, T, R, B, S, and N type thermocouples.
The MECO 333P+ provides excellent flexibility with features such as programmable output function, range conversion, cold junction compensation, numeric modifier keys, auto power-off, and reverse connection/process protection up to 30V. These functions allow users to perform accurate calibration of transmitters, controllers, PLC inputs, electric valves, and industrial measurement systems.
Designed with a large LCD display and user-friendly keypad, the calibrator provides clear readings and simple operation during field testing. Its built-in 24mA drive current capability allows simulation and testing of two-wire transmitters, while the compact handheld design makes it convenient for both laboratory and on-site calibration work.
The MECO 333P+ is widely used in process industries, manufacturing plants, automation systems, electrical maintenance departments, and calibration laboratories. Its accurate signal generation, multi-function capability, and rugged portable construction make it a reliable choice for professionals requiring precise testing and calibration of industrial instruments.
