The 25121 probe combines a 304SS protective tube and high-temperature PTFE-insulated compensation leads for temperature control in catering equipment. The insulated measuring junction offers a 0-500°C sensing range. Alkar#25121 is a design reference; it does not by itself establish equipment compatibility or certification.
| Model | Element | Junction | Range | Accuracy | Sheath | Lead color |
|---|---|---|---|---|---|---|
| 25121 | J | Insulated | 0-500°C | ±0.4%t | 304SS | Brown |
| Insertion | Compensation lead length | Tube diameter | Tube-to-lead connection | Lead conductor choices | Termination |
|---|---|---|---|---|---|
| 153mm | 7620mm | 3.4mm | Laser welding or hydraulic pressing | Stranded or single conductor | Bare wire |
Other dimensions can be made to suit the installation. Match the probe dimensions, lead routing and termination to the equipment; the sensing range does not specify a separate maximum ambient temperature for the lead.
