Waterproof alarm thermometer for immersion temperature measurement, Pt1000

ECO 121-3

Alarm thermometer for immersion temperature measurement in food, liquids, gases, soft plastics and bulk material, with -70.0 ... +250.0 °C range, fixed Pt1000 probe, 3-line backlit LCD and IP65 / IP67 protection.

Introduction

Temperature checks in liquids, gases and bulk material need a handheld device that is quick to read and simple to trust. With its permanently connected immersion probe, this alarm thermometer is ready for precise, instantaneous measurements without selecting or attaching a separate sensor.
 
The fixed Pt1000 immersion probe measures from -70.0 ... +250.0 °C and uses a 100 mm, Ø 3 mm V4A probe with 1 m cable. In the key range from -20 ... +100 °C, the device reaches ±0.1 K ±1 digit accuracy, while the probe response time is <3 s in water at 0.4 m/s. Min/max and hold functions help users capture important values directly at the measuring point.
 
Daily field use is supported by the compact, break-proof ABS housing and ingress protection (IP) IP65 / IP67. The illuminated 3-line LCD remains readable in changing light conditions, and the optical and acoustic alarm function helps identify limit deviations quickly. Two AA batteries provide more than 5000 hours of operation without backlighting.
