Introduction de produit

This bench-top calibrator combines a sealed stainless working chamber with mixed-flow humidity generation, thermoelectric temperature control and an integrated reference channel. Dry and humidified air streams are circulated through the chamber to establish repeatable test conditions without an external compressed-air supply. A front touchscreen manages setpoints, stabilization status and programmed sequences, while interchangeable door sleeves accommodate different probe diameters and keep each insertion point sealed.

Key Features

Dynamic mixed-flow generation supports multiple relative-humidity setpoints in one session.

Thermoelectric chamber control limits temperature-driven errors during humidity comparison.

Six sealed probe ports allow several instruments to share the same controlled condition.

Integrated reference input displays chamber conditions beside the programmed setpoint.

On-screen sequence control reduces repetitive manual changes during multi-point calibration.

Transportable bench enclosure supports laboratory use and on-site instrument checks.

Préoccupations du client produit

Reliable humidity calibration depends on placing the instrument under test and the reference in the same stable temperature and water-vapor environment while preventing ambient leakage around the probes.

Single-point checks can miss nonlinear sensor error across the working humidity range.Programmable sequences expose every connected instrument to several controlled relative-humidity setpoints.

Temperature mismatch between a probe and its reference can distort relative-humidity results.A circulated thermoelectric chamber holds the devices under test and reference sensor at one controlled temperature.

Calibrating probes one by one consumes technician time and creates inconsistent conditions.Six sealed door ports support simultaneous comparison of several probes in the same working volume.

Different probe diameters can leak ambient air into the chamber.Interchangeable sleeves and blanking plugs seal each occupied or unused port around the actual probe body.
