Simple pOCKET TESTER

A compact, battery-powered tester for NAMUR, 0–10 V, and 0–20 mA sensors.

Test sensors anytime, anywhere—without an external power supply. Simpotest fits in your pocket and gives you instant, reliable readings in the field.

What is Simpotest?

Simpotest is a portable tester designed for quick diagnostics of industrial sensors. It supports NAMUR, voltage (0–10 V), and current (0–20 mA) signals, making it a versatile tool for technicians, maintenance engineers, and installers.

With built-in power output (8.2 V or 24 V), it can directly supply connected sensors—no additional equipment required.

All-in-one testing tool

Simpotest is a portable tester designed for quick diagnostics of Measure NAMUR, 0–10 V, and 0–20 mA signals with a single device.

Built-in sensor power supply

Provides 8.2 V or 24 V output, eliminating the need for external power sources.

Pocket-sized and portable

Lightweight and compact design for easy field use.

Clear real-time readings

Instantly displays output values from connected sensors.

Acoustic continuity tester

Includes a loud audible signal for quick circuit testing without looking at the display.   

Key Features & Capabilities:

  • Triple Mode Operation: Easily switch between NAMUR, 0–20mA, and 0–10V modes by holding the mode button for 2 seconds.

  • Intuitive Display: A clear digital display shows the measured value in corresponding units, the active mode, and the current battery status.

  • Sensor Power Supply: The device provides output voltage to power the connected sensor. For safety, the output is equipped with internal overcurrent and short-circuit protection (against GND).

  • Smart Continuity Tester: Features a loud acoustic signal and a bright green LED for circuit testing.

  • Intelligent Protection: In current measurement (mA) mode, the device automatically switches to voltage (V) mode if it detects a potential risk of input damage from the output voltage.

  • NAMUR Diagnostics: Visual feedback via dual-color LEDs. Red indicates an open circuit (sensor not connected), while Green signals a triggered NAMUR sensor.

Technical Specifications:

  • Charging: USB-C port (requires a 5V/1A charger or better).

  • Battery Management: Integrated LED status indicator – Red for charging, Blue for fully charged. Real-time battery level is also visible on the LCD.

  • Safety: Built-in electronic protection for robust field use.
