Senseca ECO 121-3 Waterproof Alarm Thermometer
The primary focus in the development of the ECO-line was place on the essential functions of the measurement technology.
Pure measurement with a focus on precision, speed and reliability packaged in a compact housing distinguish an impressive price/performance ratio.
The handheld measuring devices also impress with their ergonomic design, dust and water-protected design according to IP 65/67 and the illuminated display.
The compact thermometer is available with a practical BNC connection for interchangeable sensors or as a complete device including sensor with maximum overall precision.
The device redefines our entry-level measurement class – test protocol included.
The matching sensors can be used at temperatures of up to 250 °C (incl. handle and cable) and are distinguished by their compact design and small tube diameter.
Integrated: High-quality Pt1000 sensors.
Display
Thanks to the backlight, the three-line LCD display offers ergonomic wide-angle visibility - by day and by night.
The HOLD function enables the display values to be frozen.
Power supply
2 powerful AA batteries, the energy-saving design and the configurable automatic switch-off function ensure long operation.
Configurable LCD backlight for further energy saving options.
