Your Latest Eltek Newsletter
 For subscribers to the Eltek Newsletter
I hope you have had an enjoyable summer break.  In this newsletter we have a case study about the Royal Air Force museum in the UK.  The RAF celebrated its centenary this year, and Eltek have been delighted to supply monitoring equipment to be used with the new exhibits at the RAF museum.

Air Quality continues to be a major area of interest to Eltek, and we are delighted to have been awarded a contract by The Bartlett School at University College in London to supply a significant number of our AQ110 air quality monitors.  The monitors are being used in an extensive study of schools, hospitals and public buildings to monitor indoor and external air quality.  There has been more press publicity about the impact of air quality on learning and health over the summer and Eltek is well placed to provide technical advice and equipment. Please do contact us if you are interested.

As ever, we are grateful for your feedback and suggestions, please keep them coming.

With kind regards, 



The Royal Air Force at 100

In May, I had the opportunity to assist D-Tech Systems with the installation of some of our Eltek transmitters at the RAF museum in London.  The museum has been improved and expanded as part of the centenary celebrations of the Royal Air Force.    The museum is a fascinating place to visit and the team at the museum have designed the exhibition to show the progression of the RAF through the ages. The new exhibiton is well worth a visit if you are in the UK.
The curators have to ensure that all exhibits are protected from deterioration and the environmental conditions are maintained within acceptable limits.   Eltek devices are used to monitor many individual displays to ensure they are maintained at the correct temperature and humidity.    D-Tech's team have many years of experience of installing Eltek systems, during the design phase they surveyed the site and created an installation plan in conjunction with the team from the museum.  On the day I visited, the installation process was well organised and co-ordinated and completed rapidly and efficiently .  If you wish to see more details of the installation, please click on the link to the case study in the blue bar below.

Air Quality

Growing Demand for Air Quality Monitoring
We have been shipping a growing number of Air Quality Monitring units in response to customer demand.   We are delighted that The Bartlett School at University College in London is undertaking a study of schools, hospitals and public buildings in London using the AQ110 to collect data on CO2, NO2, CO, Particulates and VOC's.  We shall include a case study of this work in a future edition of the newsletter.

Eltek is following many air quality related Twitter feeds, if you are a Twitter devotee you may wish to join us @EltekData

Mini-Logger product range
How to choose what I need?
I need a compact stand alone basic logger......
Choose Mini Squirrel  MS series products

I need a compact logger, but one day I might need to expand to a multiple transmitter system.....
Choose logmitter LM series products

I just need a transmitter, but my data is critical and I need to be sure it�s backed up in case of transmission failure...
Choose M series devices

The Mini Squirrel
The first release of the GenII MS �Mini Squirrel� series is intended for RH, temperature and CO2 applications. 

The dataloggers are battery operated and ideal for short or long term environmental monitoring.

Mini Squirrel is ideal for monitoring smaller spaces such as galleries or laboratories. A feature of the Mini Squirrel is ease of deployment and data download. A top panel mounting jack socket is provided for data download.

The scrolling LCD display provides real time sensor values and screen prompts inform the user that the logger is set up and ready to go as required.

Eltek�s Darca Lite Windows software is designed for use with the MS Mini Squirrel, enabling the user to configure, download data, and graph historic data quickly and easily.

The Logmitter

The GenII Logmitter range is a series of devices launched by Eltek in 2017 that can be configured either as a conventional GenII transmitter or as a standalone datalogger.  

Eltek�s GenII Logmitter is a first in that you get a compact self-contained and highly accurate device that is a logger or a transmitter as required.

System Operation
Configured as a logger and deployed alone, it is ideal for smaller spaces and short term or temporary events in sites such as galleries or laboratories. For large buildings, e.g. city block museums, storage areas or research laboratories, it can be deployed as a transmitter with other Logmitters which are also configured in transmitter mode, reporting to a receiver.

Used together with Eltek Darca Heritage software, which is designed for conservators and collection managers alike, it provides the ideal solution for detailed environmental audits and day to day monitoring. Logmitter simply grows with your expanding requirements with all data available on a common platform.

Transmitter with backup memory

The GenII M series is a family of transmitters that incorporate standard GenII transmitter features plus backup memory, which safeguards data should a temporary interruption of the logging infrastructure occur. 
Designed to meet the data reliability targets for the pharmaceutical and laboratory sectors, the first release of the GenII M series includes models with inputs for thermistor, thermocouple, and PT100 sensors together with built-in RH and temperature and inputs for incubator monitoring applications.

System Operation
The GenII M series retains the standard GenII transmitter specification and adds 12,000 readings of built-in memory in continuous overwrite mode. This means many weeks of data can be held in the transmitter.
The logging interval is configurable, and is ideally set to be the same as the system logging interval. However the back up memory logging interval and therefore memory usage and granularity can be optimised depending on the user's requirements.
Data is downloaded using the TX download program and is saved to the PC in Windows CSV format. Each reading consists of the reading value and time stamp.
