Season's Greetings

Lucian and Linda Hatfield and the whole team at Eltek would like to wish you a very Happy Christmas and a Prosperous New Year.   We would like to thank you for your support and your custom during 2017. 
This newsletter is aimed at you, our distributors, and I would like to thank you for the constructive feedback we have received from the recent editions.  We are also sending a modified version of the newsletter to all customers who have signed up, please let Brian know if you wish to send a link to the Eltek customer newsletter to your customers.  

In 2017 we have released some interesting new products and these are now beginning to gain significant interest, in particular our SRV250 logger which provides access to 'The Cloud' using the mobile telephone network, allowing Web Browser access to current data,  and the AQ110 which has been released in response to the growing demand for monitoring of air quality especially in public buildings.   Brian and Lucian have been visiting a number of you recently and will continue to do this into the New Year to help understand the latest product requirements, sales opportunities and challenges you meet.  

We have a received a number of offers for producing case studies for inclusion on the New Web Site and in our customer newsletter and several are now underway.  Many thanks to all of you who have offered your time to help produce these.

Wishing you all the best for Christmas and the New Year,

With kind regards

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 a 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.
