Senonics
SENONICS MANUFACTURES MODERN, HIGH QUALITY, ROBUST TRANSPORTATION LOGGERS.
Suppose you are to transport some sensitive item, chemical or food product and would like to know the exact conditions under which it was transported. You can use our loggers to record the complete environmental condition throughout the journey. Our loggers offer the largest logger depth of all similar portable loggers so you will never run short of logging space.
Try from our miniature Minnow 1.0 logger operated from a single coin cell battery or our new Minnow 2.0 display enabled logger.

Minnow 1.0
A title
Image Box text
Minnow 1.0 is commonly used in transport applications including but not limited to transport of:
- Sensitive/Fragile Items
- Food
- Animals/Livestove
- Plants
- Chemicals
- Medicines or Organs
Features
- Temperature & Humidity Logger (Coin Cell)
- High accuracy temp & humidity logging
- 65520 sample depth (temp & humidity)
- Temperature and humidity alarms
- Simple to use PC application for Windows
- USB configuration and data extraction
- Operates on a standard CR2450 coin cell
- 35mm x 60mm x 15mm
Suppose for example you would like to transport some delicate or fragile cargo from one location to another. By attachment of a Minnow 1.0 logger one can record temperature and humidity conditions during the journey. At the destination you can then extract the logged data using a very simple PC application and see graphically or in raw data format the changes in environment over time.
TEMPERATURE AND HUMIDITY MEASUREMENT
Minnow 1.0 offers accurate and repeatable logging for temperature and relative humidity. Temperature is measured to an accuracy of +/- 0.13C over the range 0C to +65C and +/- 0.3C over the full range -25C to +75C. Relative humidity is measured to an accuracy of +/- 2.0% over 10% to 90% humidity range and +/- 4.0% over 0% to 100%. Both temperature and relative humidity are logged at a user configurable logging rate which can be set in a PC application program.
NIST TRACEABLE CALIBRATION
Minnow 1.0 is available with an optional NIST traceable single point calibration at any temperature between 15C and 35C or 0C. Once calibrated Minnow 1.0 is accurate to +/- 0.07C within +/- 20C of the calibration point.
ALARMS
When you would like to guarantee that items are transported within particular environmental limits then one can also set operating ranges above or below which light indicators will be activated so that the user can become aware that the desired transportation conditions have been exceeded.

LOGGING STORAGE
The Minnow 1.0 logger is equipped with the largest logging memory when compared with comparable portable logging devices currently available. The Minnow 1.0 logger has provision for an impressive 65520 storage items each of which is a time-stamped recording of temperature and humidity.
DEVICE ID & DATA SECURITY
The Minnow 1.0 logger enables each device to have a 16 character name. This can be helpful when the user has multiple logging devices and one would like to distinguish between them for example based on location. Logging data may also be password protected so that data may only be retrieved from the device by supplying a user supplied password.
LONG BATTERY LIFE
Minnow 1.0 runs from a single CR2450 coin cell better available from supermarkets or online battery stores over the internet. The logger can log temperature and relative humidity for up to 4 years.
SIMPLE TO USE PC APPLICATION
Minnow 1.0 comes with a very easy to use PC application. The application is used for configuration of the logger, extraction of logger data, graphically viewing of logging data, spread sheet analysis of logging data and saving of logging data to file (typically in comma separated value CSV file format) for third party applications such as Microsoft Excel. The graphical user interface is completely intuitive in terms of configuring new devices and extracting logging data from a field device. When the user has multiple devices requiring the same setup then one can preload the application with a logger setup from a saved configuration file to help expedite the process and ensure all loggers get setup identically. The application does not require any driver installations to connect to your logging device. Just download the program from our home page, run it and then plug in you device. As simple as that! Currently the PC application is available for Windows XP, Vista, Windows 7, Windows 8 and Windows 10. It is also supported on Mac.

LOOK AND FEEL
The Minnow 1.0 design is compact, elegant and simple. Care has been taken to ensure the design is stylish and only makes available buttons, indicators and connectors which are intuitive and uncomplicated. Minnow 1.0 has a handy key ring attachment for easy transportation.
MOISTURE RESISTANCE
Every logger circuit board assembly is epoxy coated to protect the device from wet and condensing enviroments.

Minnow 2.0
A title
Image Box text
The Minnow 2.0 is a second generation logger coupling usual robustness and high accuracy for which Senonics is known, with a new professional look and feel.
Key features include:
- High accuracy temp & humidity logging
- LCD Display
- IP-65 water/dust proofness
- External sensor probes available
- 65000 sample depth (temp & humidity)
- Temperature and humidity alarms
- Operates on two CR2032 coin cells
- 43mm x 79mm x 12mm
Minnow 2.0 can be used for transport applications. Suppose for example you would like to transport some delicate or fragile cargo from one location to another. By attachment of a Minnow 2.0 logger one can record temperature and humidity conditions during the journey. At the destination you can then extract the logged data using a very simple PC application and see graphically or in raw data format the changes in environment over time. With its built in display, Minnow 2.0 can equally be used in-situ – for example in pharmaceutical storage.
TEMPERATURE AND HUMIDITY MEASUREMENT
Minnow 2.0 offers accurate and repeatable logging for temperature and relative humidity. Temperature is measured to an accuracy of +/-0.13C over the range 0C to +65C and +/-0.3C over the full range -25C to +80C. Relative humidity is measured to an accuracy of +/-2.0% over 10% to 90% humidity range and +/-4.0% over the full range 0% to 100%. Both temperature and relative humidity are logged at a user configurable logging rate which can be set in a PC application program.
NIST TRACEABLE CALIBRATION
Minnow 2.0 offers an optional NIST traceable single point calibration. Once calibrated Minnow 2.0 is accurate to +/-0.07C within +/-20C of the calibration point.
DISPLAY
Minnow 2.0 has a clear LCD display with wide viewing angle, capable of showing temperature with a resolution of 0.01C and relative humidity with a resolution of 0.1%. Use of the display button on the logger will cycle through current, maximum, minimum and average logged values.

ALARMS
When you would like to ensure environmental conditions are kept within particular limits, one can also set operating ranges above or below which light indicators will be activated so that the user can become aware that the environment has gone outside allowed limits. The alarms are also visible on the display.
LOGGING STORAGE
The Minnow 2.0 logger is equipped with the largest logging memory when compared with other portable logging devices currently available. Minnow 2.0 has provision for 65000 storage items each of which is a time-stamped recording of temperature and humidity.
WATER/DUST RESISTANCE
Minnow 2.0 has been designed with special care to avoid water or dust from entering the logger. Minnow 2.0TH is rated IP-65.
EXTERNAL SENSOR PROBES
Minnow 2.0 can be used with external temperature and humidity sensor probes.
