Spike thermocouples and profile sensors are designed to travel through a furnace or oven with a product load, recording the temperature profile that the product experiences — not the ambient furnace temperature. Critical for validating furnace uniformity per AMS 2750, CQI-9, IPC-7711, and JEDEC reflow soldering standards.
A pointed-tip MIMS thermocouple designed to be pushed through foam, PCB, food product, or other materials to measure internal temperature during a process cycle. Exposed or lightly insulated tip, MIMS body, miniature TC connector. Used for thermal validation of reflow ovens, wave solder machines, conformal coating ovens, and food pasteurization tunnels.
Survey thermocouples for AMS 2750 Temperature Uniformity Surveys (TUS) and System Accuracy Tests (SAT). Type K, N, or noble metal (R/S) per AMS 2750 Tables 1 and 2. Bayonet or compression fitting for easy installation at survey grid points. NIST-traceable calibration certificate required for each survey element.
Pt100 profile sensors for semiconductor diffusion furnace tube temperature mapping. Small-OD 316SS or quartz-sheathed probe, multiple calibrated elements at defined depths, compatible with 200mm and 300mm wafer tube access ports. Class A, 4-wire, with NIST-traceable multipoint calibration at process temperatures.
| AMS 2750 Instrument Type | TC Type (Allowed) | Tolerance Required | Cal Interval | Thermometrics Model |
|---|---|---|---|---|
| Type 1 (Noble) | R or S | ±0.5°C or 0.1% whichever greater | Annually or as used | TC-PRO-1 (R or S) |
| Type 2 (Base Metal) | K, N, E | ±1.1°C or 0.4% whichever greater | 3 months or as used | TC-PRO-1 (K or N), TC-SPK-1 |
| Type 3 (Base Metal SLE) | K, N, E (SLE) | ±0.6°C or 0.2% whichever greater | 3 months or as used | TC-PRO-1 with SLE wire |
| Type 4 (Base Metal) | K, J, N, T | ±2.2°C or 0.75% whichever greater | 6 months | Any standard TC series |
| Type 5 (Noble) | R, S, B | ±1.5°C or 0.25% whichever greater | Annually | TC-PRO-1 (R, S, or B) |
AMS 2750 and CQI-9 require that all survey thermocouples have a current NIST-traceable calibration certificate documenting the actual error at calibration temperature(s). Thermometrics issues calibration certificates with every TC-PRO-1 survey assembly. Certificates include sensor serial number, calibration date, reference standard traceability chain, and individual junction error at all test points. Recalibration service available on returned assemblies.
