Are you working in an IVF lab or any other lab handling living cells? Then you know how crucial the right environment is for said cells.
With NiloChecker, you can monitor, control, and calibrate incubators, workstations, heated surfaces and more. No need for multiple instruments from different manufacturers.
As a gold standard within Quality Assurance and Quality Control, the NiloChecker 500 supports measurement of several different modalities in the laboratory working with living cells. Temperature, CO₂/O₂ Concentrations, Pressure and Flow, Humidity, Air Flow, RPM – and we are constantly expanding your options with more probes. Simply connect your preferred probe and start monitoring your parameter of choice.
The Solution is available in two configurations. The online monitoring version automatically transfers data from equipment to the cloud for storage and documentation, providing a more strategic approach to overall operations of your lab.
The standard version is a preferred all-in-one device for spot checks and calibration, used primarily when the need for data storage is not paramount.
Save valuable time on process and quality control. Five ports make it possible to perform up to 10 temperature measurements simultaneously – or you can measure CO₂, O₂, temperature, and humidity at the same time.
Data is stored with both minimum and maximum, as well as deviation and average values – saving you time and effort.
The 7’’ touch screen eases use of the intuitive software guiding you through the process.
It assists you in performing measurements in accordance with international standards and manufacturers’ recommendations.
The screen can be controlled with gloves.
Explore our current range of probes below.
All probes share the same unique design: a sensor connected to a microcontroller, which communicates with the NiloChecker through a data cable. Once connected, the probe tells the NiloChecker what type it is.
All probes can be connected to any of the five ports in the device. This gives you full flexibility to combine different types of probes in one session and generate one measurement report. Simply plug in, measure and collect data.
Mounted on the wall, the NiloChecker monitors vital parameters in your equipment. However, it can also easily be used elsewhere in the laboratory as a handheld device.
Simply unplug it, stop monitoring, and plug in new probes in different areas of your laboratory.
The device’s high-capacity battery ensures hours of measurement time between charging.
The device is fully digital and needs no calibration. Measurement probes can be controlled and calibrated independently of the NiloChecker.

KT106 offers a novel opportunity to measure temperature in small volumes hard to reach. Using a state-of-the-art PT100 microsensor, it is now possible to measure temperature inside a medium droplet as small as 25µL. The measuring head being only 800µm will contribute minimally to disturb measurement and dissipation is also minimised, making it ideal for droplet measurements.
KT106 Benefits
The KT106 – K-Type Droplet Probe is particularly well suited for measuring temperature in very small volumes. With a measuring range of -25 to 250 Celsius and a relatively long (100cm) Teflon cable this probe is highly versatile, providing for a wide range of applications. Laws of thermodynamics dictate, that the smaller the volume the higher the exposure and sensitivity to changes in the environment. We therefore recommend to always aim for the most stable surroundings, and if measuring in an Air flow cabinet to insulate the sensor tip. When performing droplet measurements, although any given measurement may be accurate, precision will be almost always be compromised. Accordingly, repeated measurements will provide a more realistic representation of reality.
