WIKA Temperature Calibrators – precision for lab & field
WIKA temperature calibrators deliver stable, uniform and traceable temperatures to calibrate RTD/PRT, thermocouples, thermistors, plus IR thermometers and thermal imagers. The portfolio spans portable dry-wells, liquid baths, high-temperature furnaces and blackbody sources—with interfaces for data logging and calibration software.
Key capabilities (model-dependent): ranges about −80…+1,200 °C, multi-zone control, stability down to ±0.005 °C, uniformity <0.02 °C, external reference input, multi-channel measurement, ramp/soak, USB/LAN (some with Bluetooth) and PDF/CSV export.
ICS Schneider Messtechnik supports selection, insert/sleeve design, uncertainty budgeting and procedures, and provides optional factory/DAkkS certificates for calibrator and reference probes.
FAQ on WIKA Temperature Calibrators
Answers on technologies, accuracy, inserts, immersion, IR testing, documentation, integration and best practices.
Which calibrator types does WIKA offer?
Dry-wells for clean field work, liquid baths for maximum uniformity, high-temperature furnaces for >650 °C and blackbodies for non-contact IR verification.
What is the difference between stability, uniformity and accuracy?
Stability = temporal variation; uniformity = spatial evenness within block/bath; accuracy = deviation from true value determined with a reference probe.
What performance is typical?
| Criterion | Dry-well | Liquid bath | Blackbody |
|---|---|---|---|
| Stability | to ±0.01…0.03 °C | to ±0.005…0.02 °C | model-dependent |
| Uniformity | ≤0.02…0.1 °C | ≤0.01…0.03 °C | consider FOV/aperture |
| Range | −35…+650 °C | −80…+300 °C | +50…+1,100 °C |
Why should I use an external reference probe?
The block display does not always match the tip temperature at the DUT. A PRT/RTD reference close to the DUT minimizes gradient and coupling errors.
How do I choose the correct insert/sleeve?
Bore = DUT Ø + 0.1…0.2 mm with continuous fit; material aluminum/copper (<300 °C) or Inconel/stainless (high T). Multi-hole sleeves separate reference and DUT(s).
How much immersion depth is required?
At least 15–20× the probe diameter or beyond the sensing element. For short probes use deep/extension sleeves and insulation caps.
What practical point sets should I use?
Example: −20/0/50/100/150/200 °C, each with a defined stability window (e.g., 60–300 s ≤ ±0.02…0.05 °C) and up/down runs for hysteresis.
How do I calibrate thermocouples correctly?
Place the hot junction in the insert; enable cold-junction compensation on the instrument or measure a reference CJC; ensure tight thermal coupling.
Tips for RTD/PRT calibrations
Use 4-wire measurement, keep test current low (limit self-heating), allow sufficient stabilization time, and relieve cable strain.
How do I test IR thermometers and thermal imagers?
With blackbody sources: set proper emissivity (ε≈0.95–0.99), use correct distance/focus, ensure aperture > spot size, minimize drafts/reflections.
Which interfaces & software options are available?
USB/LAN (some with Bluetooth), SCPI/Modbus by model; integrate with calibration software for work orders, point lists, PDF/CSV reports and a full traceability chain.
How do I build an uncertainty budget?
Combine reference accuracy, stability, uniformity, indicator resolution, self-heating, heat loss and repeatability; report expanded with k=2.
Which bath fluids do you recommend?
| Fluid | Range | Properties | Notes |
|---|---|---|---|
| Alcohols | to −80…+20 °C | Very low viscosity | Flammable—ventilation required |
| Silicone oils | −40…+200 °C | Wide range, stable | Watch viscosity/aging |
| Salt baths | >+300 °C | Very high temperatures | Corrosive—extra protection |
What safety aspects apply?
Burn protection, stable placement, over-temperature protection active, PPE; for baths ensure extraction and fire safety; remove hot sleeves only with tools.
How often should I recalibrate?
Typically annually; for critical QA semi-annual/quarterly. After transport/service perform an interim check (ice/fixed points).
Can I test multiple sensors at once?
Yes—with multi-hole sleeves or baskets (baths). Limit loading, place the reference close to the DUT tips and monitor gradients.
How do I document in a compliant way?
Include as-found/as-left, point lists with stability window, traceability chain, ambient (T/RH), expanded uncertainty and signature/e-signature; export PDF/CSV.
Which accessories improve repeatability?
Precision sleeves with minimal clearance, insulation caps, stop rings for constant depth, a top clamp and probe holders.
Do you support selection & procedures?
Yes—we size the calibrator/reference, design inserts, create templates (ramp/soak, stability) and supply factory/DAkkS certificates.
