E+E HUMOR 20 Humidity Calibrator

Portable dual-pressure humidity generator for lab and field reference work — 10…95 %RH working range, OEM accuracy band 0.3…0.9 %RH, stabilisation under 3 minutes per point, independent of ambient temperature, needs only distilled water, clean oil-free air to 10 bar, and 90…230 V AC.

Key advantages

Primary dual-pressure principle — generated RH depends on pressure; suitable as a humidity reference.
10…95 %RH — accuracy 0.3…0.9 %RH (OEM product page); stabilisation <3 min/point.
Probe flexibility — chamber covers for Ø8…25.5 mm probes; up to four devices; room-mount sensors and loggers.
Four measuring inputs — switchable 4–20 / 0–20 mA or 0–1 / 0–5 / 0–10 V; 24 V DC specimen supply.
Auto calibration option — Automatic Calibration Module + PC software for multi-point cycles and certificates.

Typical applications

Calibration laboratories needing a portable RH reference.
Manufacturers of humidity sensors and transmitters.
On-site multi-point RH verification with distilled-water operation.
Accredited calibration workflows (optional accredited certificate).

Selection guide

Working range — 10…95 %RH; chamber temperature measurement accuracy typ. ±0.3 °C.
Air / water — filtered oil-free air max 10 bar (particles >0.1 µm, residual oil <0.01 mg/m³); distilled water only.
Supply — 90…230 V AC (datasheet also states 100–230 V AC, 50/60 Hz, max 20 W).
Covers / capacity — metal covers preferred for stated accuracy; compact specimens up to ~100×85×40 mm.
Certificates — DIN EN 10204-3.1 inspection certificate standard; accredited points on request (e.g. 15/55/90 %RH).
Auto kit — optional Automatic Calibration Module for unattended cycles.

Common mistakes

Filling tap water — OEM requires distilled water only.
Transporting with water at tilt >20° — drain first if tilt cannot be assured.
Expecting accuracy without the correct metal chamber cover.
Using unfiltered oily shop air — residual oil/particles damage regulators.

FAQ

Q: What certificate ships standard? A: Inspection certificate per DIN EN 10204-3.1. Accredited multi-point certificates are optional — request on RFQ.

Q: Does ambient temperature affect RH? A: By design the dual-pressure principle is independent of ambient temperature in the stated operating window.

Q: What should I send for a quote? A: Auto-kit need, covers/probe diameters, certificate type, quantity, ship-to. Compatible with systems using E+E HUMOR 20 if you need a drop-in check — we do not claim authorized-dealer status.
