Perform on-site relative humidity
calibrations

Humidity calibrator lets users of humidity sensors, transmitters and read-out devices quickly and accurately generate reference humidity conditions and perform on-site relative humidity calibrations.

Rense Instruments' S-503 humidity calibrator has been added to its range of dewpoint and relative humidity generators It lets users of humidity sensors, transmitters and read-out devices quickly and accurately generate reference humidity conditions and perform on-site relative humidity calibrations

Set points from 10 to 90% RH in steps of 0.1% RH are available from the instrument's front panel.

The calibrator has an axial fan that continuously circulates air through the test chamber for humidity and temperature uniformity.

This results in a system that stabilises within 0.5% RH of the set point in typically less than 10min.

The calibrator provides a direct readout of the measured humidity for a range of voltage and current transmitters that do not have an integral display, as well as providing a display of the percentage RH and temperature for the chamber itself.

These lightweight, transportable, self-contained units use a thin film capacitive sensor and closed loop controllers to modulate the flow of air through a saturation and desiccant chamber.

The unit has access ports for seven probes, up to 18.5mm in diameter and can be adapted to suit various commercially available humidity probes.

The S-503 can be supplied with a UKas calibration certificate if required.

It can also be specified with an independent reference standard, such as Michell Instruments' Optidew Vision cooled mirror dewpoint meter. Request a free brochure from Michell Instruments ...
