Complying with quality requirements and regulations in an IVF lab is crucial, but takes time and effort.

With the Log&Guard system you can replace the daily routine of manual snapshot measurements with continuous monitoring of critical parameters, presented in an easy to use web interface.

Log&Guard is a monitoring and alert system specifically designed to meet the needs of quality control in the IVF lab. All critical culture and storage parameters such as temperature, humidity, pH, CO2/O2, VOCs and power supply are continuously measured and documented through a network of external sensors.

Start small or go big

The flexible Log&Guard system lets you decide which and how many external sensors to be connected to the main controller. You also have a choice of data transmission by cable, wirelessly or a combination of the two.

Monitor critical parameters to create a protective environment

Controller for monitoring and warning

The controller includes; integrated PC, GSM modem, battery backup, external keyboard and flat screen, 8 alarm relay inputs; LAN interface, slot for SIM card (to be provided by the user for activating the text message alert). 

There are interfaces for temperature-, CO2- , O2 sensors and pH Online

Technical data: power supply 110-240 V AC via external power adapter, external dimensions 260 x 300 x 90 mm (LxWxH), LCD display, battery service life approx. 20 min

Easy to use software program

Log&Guard operates on a web interface based software platform, easily accessible from any computer in your local network, and does not require a separate computer.

Alarm conditions and thresholds, measurement intervals and many other parameters can be set individually to perfectly adapt the monitoring network to your individual lab. Measured data can be downloaded for long term storage.

Never miss an alarm

The Log&Guard system will alert you in case any parameter is out of range. Besides acoustical and optical alerts in the lab you can also be notified by text messages on your phone.
