Fits compact dry-block temperature calibration where you need an Ametek Jofra CTC covering model bands from −25 °C (CTC-155) up through high-temperature CTC variants with color display and optional STS reference input.
Key advantages
- Model bands — CTC-155 −25…155 °C; CTC-350/652/660 mid-high; CTC-1205 to 1205 °C class
- Accuracy (CTC-155) — ±0.3 °C internal; ±0.2 °C with external STS
- Stability — CTC-155 ±0.04 °C typical
- Immersion — 120 mm (CTC-155) up to ~190 mm on tall models
- UI — Multi-info color display; C models accept STS external reference
Typical applications
- Field dry-block sensor calibration.
- Compact workshop temperature cal.
- STS-referenced higher-accuracy work.
Selection guide
- Temperature band — Cold CTC-155 vs high CTC-1205
- Immersion depth — Probe length
- External STS — C-model need
- Inserts — Well diameter set
Common mistakes
- Probe shorter than required immersion.
- Wrong model for temperature band.
- Ignoring insert clearance for sensor OD.
When to RFQ / what to tell us
- CTC model, inserts, STS options.
