Introduction
Nokeval Ovasense Neo series measuring instruments are Bluetooth® Low Energy compatible devices
designed to be used together with Nokeval Ova® mobile application and Ovaport service.
Ovasense Neo product family includes the following models:
Ovasense Neo: thermometer equipped with an 80 mm long, 2 mm diameter stainless-steel probe with
a sharp needle tip. This model is intended for measuring the internal temperature of soft, penetrable
products like food.
Ovasense IR Neo: non-contact thermometer equipped with an infrared (IR) sensor. This model is
intended for measuring the surface temperature of objects without touching them.
Use
Preparations
1. Download and install Nokeval Ova mobile application on your mobile device from Apple App
Store or Google Play Store.
2. Ensure that Bluetooth is turned on in your mobile device and that you give all requested
permissions to the Ova mobile application.
3. Log in to the Ova mobile application (Ova app) with your Ova / Ovaport user account.
Measuring
1. Start Temperature measuring function within the Ova app. You are instructed to turn on the
measuring device.
2. Turn on the device by briefly pressing its power button.
3. Blue LED light on the device starts blinking in bursts of two blinks. This means the device is
searching for a connection. Move the Ovasense Neo close to the mobile device. Ovasense Neo
connects to the closest mobile device it detects.
4. When Ovasense Neo and the Ova app have connected, the blue LED blinks steadily and the
measuring result updates on the Ova app display continuously. Note that the Ovasense Neo will
turn off automatically after 3 minutes. If this happens, restart and reconnect the device by
pressing its power button again.
5. Start measuring. Refer to model specific measuring instructions on the next page.
6. When the reading on the Ova app display has stabilized, press the power button on the
Ovasense Neo or tap the round trigger button on the Ova app display below the reading. The
measurement reading is locked.
7. At this phase, you can reject the result by tapping the grey button with a cross symbol. If you do
this, the Ovasense Neo automatically resumes operation. Continue measuring and lock the
reading again when ready.

8. Save the measuring results by tapping the Save button on the Ova app display.

Measuring with Ovasense Neo
Push the sensor probe carefully into the product at least 30 mm deep. Do not use excessive force for
example to try to push the probe into a frozen or hard product. Be careful also when penetrating plastic
foils or similar surfaces. The sensor probe can be damaged or bent if you use excessive force on it.
Wait until the reading has sufficiently stabilized on the Ova app display. You can speed up the
measuring process by pushing the probe into the product before turning on the device and connecting
it to the app. This way the temperature starts to stabilize even before the readings appear on the
display.
Lock the measuring result by pressing the power button on the Ovasense Neo or tapping the round
trigger button on the Ova app display. Save the result.
Measuring with Ovasense IR Neo
Point the lens of the IR sensor directly towards the target object. Measuring distance should be
between 5 to 20 cm. The smaller the target the closer the distance should be. The distance should be at
most 4 times the smallest dimension of the target object. The surface of the target object must be matt
or rough in texture, it should not gleam or reflect light. Shiny or transparent objects cannot be
accurately measured.
Check the measuring results on the Ova app display. It should stabilize in seconds. If the result is not
what was expected, make sure that the measuring distance is as short as possible. Measurement error
of couple of degrees is possible depending on the surface properties of the target object.
Lock the measuring result by pressing the power button on the Ovasense IR Neo or tapping the round
trigger button on the Ova app display. Save the result.
Maintenance
Ovasense Neo series devices are delicate measuring instruments that need to be handled with care.
Even though the case is made of durable plastics the sensor or internal electronics can be damaged by
drops or hard impacts. If there is any suspicion that the device is damaged, send it to be checked and
serviced.
Replacing the battery
Device is powered by one LR03 (AAA) size 1.5 V alkaline battery. The battery is not user replaceable.
Annual service and calibration subscription of the device includes the periodic calibration of the sensor
and battery replacement. Under normal use and conditions, the battery will last for at least a year. If
needed, send the device to service for battery replacement.
Storage and cleaning
It is important to keep the device and especially the sensor or lens clean. Clean the device using a soft,
non-abrasive cloth moistened with a mild detergent solution. Be careful not to scratch the IR sensor’s
lens. Do not use any abrasive devices or substances when cleaning.
