Page 6: Instrument Description
SADPmini2 User Manual Instrument Description The SADPmini2 is a fully self-contained, micro-controller based, battery operated dewpoint hygrometer primarily used for mobile analysis and short term continuous monitoring. Using an ultra-high capacitance aluminium oxide sensor and a high accuracy, high speed, Analogue to Digital Converter (ADC), the SADPmini2 monitors dry industrial process gas and dry compressed air samples.

Page 8: Functional Description Of Desiccant Chamber
SADPmini2 User Manual Functional Description of Desiccant Chamber Keeping the sensor dry between tests makes sure that the SADPmini2 is ready to carry out rapid sample checks. The design of the Desiccant Head achieves this by surrounding the Aluminium Oxide Sensor with desiccant, keeping the sensor dry when not in use.
Page 9: Important Information
SADPmini2 User Manual Important Information Symbols Table Symbol Description Lithium-ion Battery The SADPmini2 is powered by a single lithium-ion battery. The battery may be exchanged by an authorised agent with the necessary training, support systems and accreditation. Only use the USB power supply supplied with the instrument to charge the battery.

Page 12: Installation
SADPmini2 User Manual Installation This section details the sample specific SADPmini2 installation procedures and the instructions for obtaining the correct result from sample gas. 3.1 Gases to avoid 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.
Page 13: Gas Sampling System
SADPmini2 User Manual Gas Sampling System DO NOT Do not allow the sample pressure to exceed 0.3 bar / 4 psi above ambient NOTE To maintain sample integrity and minimise equilibration time the system should be as simple as possible and of minimum swept volume. NOTE The sample tube should be stainless steel for very dry gas applications.
Page 14 SADPmini2 User Manual Clean Gas < 10 Bar Reduce positive pressure gas to atmospheric pressure. Use a needle valve at low pressures (<10 barg) to control flow and pressure drop. Clean Gas > 10 Bar Reduce positive pressure gas to atmospheric pressure.
Page 15: Installation And Sample
SADPmini2 User Manual Installation and Sample Install the sample piping system and equipment as per the required installation configuration. NOTE: The SADPmini2 is not connected to the inlet piping system at this stage. Open the sample Isolation Valve and adjust the needle valve/ regulator to allow a flow of 5-15 litres per minute to atmosphere through to sample pipe.
