Martindale Loop Calibrator, Battery Operated, 0 - 20 mA, 28.5 V Output, 10 μA Resolution TEK300

The Martindale TEK300 Loop Calibrator is an advanced, compact instrument engineered for the accurate delivery, monitoring, and simulation of direct current signals in process control and industrial environments. Designed for battery-powered portability and ruggedness, the TEK300 enables technicians and engineers to perform calibration, troubleshooting, and signal injection tasks across a wide spectrum of industrial automation and laboratory setups.

With the ability to act as both a source and a sink, the TEK300 generates and measures currents up to 20 mA, making it highly suitable for process instrumentation and general-purpose signal simulation. The calibrator incorporates a monitor mode, allowing direct readout of loop currents on its digital LCD display to support real-time measurements directly in the field or on the bench.

Offering a fine resolution of 10 μA and a DC/DC converter output of 28.5 V, this loop calibrator excels in delivering highly accurate and stable current for precise adjustment and verification. Temperature drift is limited to 150 ppm/°C, and the device’s linearity is maintained at 0.15%, ensuring high-fidelity signal integrity under varied industrial conditions.

Engineered for safety, the unit features overload protection and battery condition/error indication LEDs, providing clear operational status and feedback to the user. Its ABS housing ensures robust protection and durability, while its compact dimensions (180 mm × 100 mm × 44 mm) and light weight (380 g) make it readily portable for both on-site commissioning and ongoing maintenance schedules.

Ease of use is further enhanced by a clear three-digit LCD display, which communicates precise readings even in less than optimal lighting. The calibrator operates through a broad temperature range (0°C to 50°C), supporting applications in both controlled laboratory conditions and challenging industrial locations. It supports two PP3 alkaline batteries, though some specifications may reference AA batteries; verify battery requirements for your use case.

The TEK300 is tailored for signal simulation, calibration, and maintenance of industrial process loops and control systems. It is particularly well-suited for sectors like process automation, manufacturing plants, instrumentation workshops, and plant commissioning teams. Common use cases include current loop verification, transmitter simulation, and system diagnostics.

The device complies with relevant safety and ESD standards, including ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007, confirming its suitability for sensitive electronic environments.
