Schelt Technology

The ECO 122 is a convenient insertion thermometer for soft soils, compost, agricultural windrows and bulk materials.
The sophisticated probe tip offers a best possible compromise between speed and robustness.
The connection between the indicator and probe is welded from solid stainless steel for reliability in tough measurement applications.

Precision, speed and reliability packed in a compact and
robust housing makes the instrument a reliable partner for professional users.
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 additional energy-saving options.

When developing the ECO 51x series, the focus was placed on the essential functions of measurement technology.
Pure measurement with a focus on precision, speed and reliability, packaged in a compact housing, is what makes the outstanding price-performance ratio, Made in Germany, possible.
The handheld meters also impress with their ergonomic design, dust and water-protected design in accordance with IP 65/67 and the illuminated display.
The compact pH meters are a real alternative to pH sticks on the one hand and high-priced, complex devices on the other.
The ECO 510 meter enables measurements in the pH range, while the ECO 511 also offers the option of pH/redox measurements with a temperature input (Pt1000)
