The gopher LITE is an accurate and reliable wireless monitoring combining 5 instruments into one. The gopher can measure pH, Temperature, Humidity, and Barometric Pressure all at the same time.


Ensure the gopher is plugged into the correct outlet.

For best results, ensure the gopher well has been soaking with Buffer A for 12 hours or more.

Unpacking and Installation

The gopher will come with the following materials. Ensure all materials are complete and undamaged when received.

  • 1 x Bridge
  • 1 x Sensor
  • 5 x Silicone Lid
  • 1 x Mini-USB Cable
  • 1 x USB Power Adaptor
  • 1 x Wireless Charging Docking Station
  • 1 x Sensor Storage Container
  • 1 x pH Calibration Kit (Buffer A, Buffer B and QC Check)

Unpacking the Lite

Unpack the Bridge and connect the power cable adaptor into the USB-C on the Bridge.

Place the bridge near the incubators where the sensor will be placed.

Plug the Bridge in an appropriate power receptacle.  If the Bridge is not setup to WIFI, the red LED will display.

Charging the Sensor

Connect the Wireless Charging Station to the monitor using the supplied USB cable. This is required when the sensor battery needs to be charged.

Remove the Sensor from the Sensor Storage Container and place the sensor on the Wireless Charging Docking Station ensuring you align the orientation correctly using the well as a guide.

When the sensor is placed correctly on the Wireless Charging Docking Station, you will see a green intermittent flashing light indicating that the sensor is charging

Using the Software (User Interface)

The software is required to view the sensor information.  Access is granted by emailing support_gopher@raeyco.com.

Access to the User Interface is done by going to he following

website:  www.labforce-gopher.com

Connecting the Bridge to WIFI

You must have access to the software.  If you do not, email support@gopherivf.com.

Log onto the software with you username and password.  Go the the Bridge tab and click on “ADD BRIDGE”.  Input the details of the Bridge and click “Save”.  Copy or record the supplied key that appears on top of the page.

Connect to WIFI by downloading the app a smart device – “BLE Scanner”

Optional – connect bridge to putty using MicrUSB connection and download putty application. This will be required if repeated attempts of the below fail.

With Bridge powered on, open BLE Scanner on the smartphone and scan for “Bridge”. You can apply a filter name “Bridge” which will make it easier to connect.

Press Connect and select the customer service

Select WriteWithoutResponse and expand “updating?”

Press “Write Value” and select Text

Enter in the SSID number by typing “ssid{name}”. For example, if your ssid name is “gopher”, you would type “ssidgopher” without the quotations.

Repeat the above for the password by typing “pass{password}”

Repeat the above again for the key that was obtained from the step above by typing “pkey{################}”. Exclude all the dashes from the assigned key.

Reboot the bridge and the LED should be green indicating the the Bridge is not connected to the local assinged WIFI.

The screen of the Bridge should display 5 rows of empty values because no sensors are connected at this point.

Connecting the Sensors to the Bridge

You must have access to the software.  If you do not, email support@gopherivf.com.

Log onto the software with you username and password.  Go the the Dashboard tab and click on “ADD SENSOR”.  Input the details of the Sensor and click “Save”.  Select the available Bridges that you want to connect the sensor to.

The sensor will automatically communicate with the Bridge and the battery level of the sensor will be displayed on the Bridge.

Place the Sensor Storage Container in a safe place when the sensor is in use.  The Sensor Storage Container is used for storing the sensor when not in use for long periods of time.

Operation Using the Software

Refer to the “Operation of the User Interface Software User Guide” for detailed instructions.

Installing and Connecting to Putty

To install Putty, download the following app to your PC or laptop;

Click here to download Putty 

Once Putty is downloaded, open the app.

Connect the micro-USB to yuor PC or laptop and open the Device Manager on you laptop or PC and navigate to Ports section and note the COM port for the sil.

In the Putty app, chagnge the Connection Type to “Serial” and cupdate the Serial Line to the correct COM Port Number.  Change the speed to 115200 and press OPEN

The Putty window should open displaying the sequence actions of the connected Brdige.


The gopHer is simple to calibrate and will require the pH buffer kit (PN1234).

Ensure the Bridge is powered on and connected to the sensor with sufficient battery charge.

On the software, select the sensor and select calibration>pH.  Follow the instructions as displayed on the software.

Rinse the Sensor well with DI water and then with 2 x Buffer A solution. Place approx. 1 mL Buffer A solution in the well and press Next and wait until further instructions appear on the Monitor.

Once the Buffer A solution is measured, the gopHer will ask you to rinse with 2 x DI water and then 2 x Buffer B solution. Place approx. 1 mL Buffer B solution in the well and press Next.

After the Buffer B has been measured, rinse the well with 2 x DI water and then rinse the well with 2 x Quality Check Solution. Place approx. 1 mL of Quality Check Solution into the well and press Next  After this step, the software will either pass the calibration or ask you to repeat the calibration.

Cleaning and Disinfection

Daily Cleaning

The appropriate cleaning frequency is dependent on the type of sample being measured. A good rule of thumb to use when sampling colored liquids is when the reference diaphragm is no longer white, the probe should be cleaned.

Both the surface of the chip (the shiny dot at the probe’s tip) and the diaphragm (the white surface on the probe tip) are to be cleaned with a brush. Place the probe in warm tap water (around 60°C / 140°F) with a mild detergent for 5 minutes, stir periodically. Scrub the probe tip with a soft brush and water with a mild detergent. After scrubbing rinse with deionized water.

Never brush the probe tip, especially the ISFET chip, before rinsing and flushing thoroughly with water (tap water, demi-water etc). Before rinsing debris and particles may be on the sensor surface and brushing them into the sensor may damage it. When in doubt, soak the probe for a while in warm water with a mild detergent.

Cleaning is performed to regenerate the diaphragm in the pH probe. The diaphragm is part of the reference electrode and is necessary for pH measurements.


Perform a ‘cold’ KCl-dip electrode regeneration by heating the Sensor to 60°C / 140°F.

With the Sensor still warm, place saturated KCl solution in the well and let it stand for twenty minutes.

Rinse the Sensor with DI water.


The Sensor is very rugged and can withstand harsh environments so any disinfecting products that your lab deems safe to use should be ok to use. It is recommended to use Oosafe with the Sensor when disinfection is required. Liquid cannot enter the Sensor but it is recommended to wipe the entire outside and the well with Oosafe or similar disinfectant.

Long Term Storage

In order to extend the life of the battery, it is important to store the Sensor in the Sensor Storage Container when not being used for long periods of time.

Place the sensor with or without buffer A in the Storage Container Compartment. The orientation of the well is shown on the compartment and must be placed in correctly in order to deactivate the battery.

If storing the Sensor with Buffer A in it, place the Silicone lid on the Sensor to avoid evaporation and check the Sensor periodically and fill with Buffer A solution when required. This will minimize any drift when using the Sensor.

To activate the Sensor after being stored, place the Sensor onto the Wireless Charging Docking Station to activate the Sensor. Not doing this will not allow the Sensor to connect with the Monitor.
