WIKA CER6000 Reference Resistors

Fits laboratory resistance thermometry and bridge comparison work where a fixed or custom reference resistor from 1 Ω to 10,000 Ω is required (CER6000-RR or CER6000-RW).

Key advantages

1 Ω–10 kΩ coverage — Fixed and custom values across CER6000-RR / CER6000-RW.
RR vs RW series — Economic AC thermometry bridge comparison (RR) or primary-standard oil-filled hermetic (RW).
4-wire / hermetic builds — RR 4-wire; RW hermetically sealed stainless oil-filled elements.
CT 70.30 tables — Tolerance and stability per WIKA CT 70.30 (RR vs RW).

Typical applications

AC thermometry bridge comparison standards in the lab.
Primary-standard resistance references needing oil-filled hermetic elements.
Custom ohmic values within 1 Ω–10 kΩ for PRT/bridge work.

Selection guide

Measuring range — Fixed and custom resistance values 1 Ω to 10,000 Ω (CER6000-RR / CER6000-RW).
Accuracy — High-accuracy reference resistors; tolerance/stability per CT 70.30 (RR vs RW tables).
Output — Passive 4-wire reference (RR); hermetic oil-filled RW for primary standards.
Supply — Passive device (no supply).
Connection — 4-wire (RR); hermetically sealed stainless steel container (RW).
Mounting — Bench / lab reference; rugged stainless steel construction.

Common mistakes

Ordering RR when the lab needs RW primary-standard oil-filled hermetic elements.
Leaving the ohmic value blank — fixed and custom values 1 Ω to 10,000 Ω.
Expecting an active supply or display — passive 4-wire reference; no supply.
Inventing tolerance numbers — use CT 70.30 RR vs RW tables; do not assume a single ppm class.

When to RFQ / what to tell us

CER6000-RR vs CER6000-RW, exact resistance value (1 Ω–10 kΩ), and any custom need.
AC thermometry bridge comparison vs primary-standard duty; quantity; ship-to.
Any calibration certificate / temperature-coefficient documentation required beyond CT 70.30.

FAQ

Q: RR vs RW? A: CER6000-RR: economic AC thermometry bridge comparison standard, 4-wire. CER6000-RW: primary-standard hermetic oil-filled stainless elements. Tolerance/stability per CT 70.30 tables.

Q: Does it need power? A: No — passive reference resistor.

Q: What should I send for a quote? A: Series, ohmic value, duty, quantity. Compatible with systems using WIKA CER6000 — we do not claim authorized-dealer status.
