SADPmini2-Ex Quick Start Guide

Product catalog summary

Introduction
This quick start guide provides essential instructions for setting up and using the Alpha Moisture Systems SADPmini2 and SADPmini2-Ex Dewpoint Hygrometers. It includes safety warnings, installation procedures, and operational guidelines.

Specifications and Safety Warnings

Ensure clean gas flow at pressures below 10 bar using a needle valve, and above 10 bar using a stainless steel pressure regulator.
Filter gases with particulate or liquid contamination using a coalescing filter.
Avoid exposure to corrosive gases such as mercury, ammonia, and chlorine, as well as strong oxidizing agents like ozone.
Do not exceed a flow rate of 20 litres per minute or a pressure of 0.3 barg/4 psi.

Installation and Operation Procedures

Install the sample piping system according to the required configuration.
Open the sample isolation valve and adjust the flow to 5-15 litres per minute to purge the system for 2 minutes.
Connect the sample pipe to the instrument once the gas is clean and dry.
For low flow or very dry gas, connect a >20 cm pipe to the outlet port to prevent back diffusion.
Allow gas to flow through the SADPmini2 for two minutes before powering on the device.
Block the instrument outlet to allow the Desiccant Head to extend fully, then unblock and allow gas flow.
Record the final reading once the sensor reaches equilibrium with the sample gas.
Depress the Desiccant Head fully after use to prevent saturation.
Close the sample isolation valve and power off the device.
Disconnect the pipework from the SADPmini2.

Navigation and Settings

Use navigation keys to access and change settings such as time, date, international settings, dewpoint and concentration units, and power saving options.

Conclusion
Follow these guidelines to ensure accurate readings and maintain the integrity of the SADPmini2 Dewpoint Hygrometer. Refer to the user manual for detailed instructions and additional information.

Reduce positive pressure gas to atmospheric pressure. Flow Indicator (optional) Use a needle valve at low pressures (<10 barg) to control flow and pressure drop. Needle Valve SADPmini2 Sample Isolation Clean Gas > 10 Bar Flow Indicator (optional) Regulator Sample Isolation DO NOT Corrosive Gases: The Sensor should not be exposed to corrosive gases (or corrosive contaminants in the gas sample) as these can chemically attack the sensor, impairing calibration accuracy and/or damaging it beyond economic repair. Examples of such gases are mercury (Hg), ammonia (NH3), chlorine (Cl2) etc. Strong oxidising...
