When it comes to remote monitoring and data logging, the first option comes to mind is usually to use external sensors. While this strategy works well with cases like temperature, unfortunately it doesn’t work well with CO2. Due to the limitation of technology available, special treatments need to be in place to make CO2 sensors to work reliably. Incubator and shaker manufacturers go great length to get this done right. If not, CO2 sensors suffer from inaccuracy, drift, early failure. Additionally, other type of sensors like temperature and humidity need to be bundled, and other parameters like motor RPM almost impossible to read by external sensors.
Another option is software packages from equipment manufacturers. This would be presumably the best option. However two factors work against this option. First, high cost of software development and low adoption rate. Each manufacturer needs to invest then recover cost from a small portion of customers. Some manufacturers just opt to no develop software package. Second, end users usually need to deal with equipment from multiple manufacturers, sometimes 4 or 5, and other types of equipment as well.
For many existing incubators and shakers, the only available interface is NO/NC alarm contacts, that outputs a binary normal/alarm signal. We have them covered as well with NO/NC adapter and the same universal monitors for other type of parameters.
The most common threat to CO2 incubators and shakers is CO2 supply runs out. One solution is automatic tank switching system. Such switch system while solves the problem most the time, suffers from high upfront cost. Remote monitoring of CO2 pressure in supply line offers cheaper alternative.
A typical laboratory usually has a complex set of equipment and environmental parameters to monitor. There are usually CO2 incubators and shakers from multiple manufacturers, many different other types of equipment like freezers, LN2 tanks, and occasionally environmental parameters like temperature and humidity. Through our modularized design and universal monitors, we offer a unified solution to monitor data from various sources including directly from equipment internal measurement, external sensors manufactured by ourselves and other sensor manufacturers. The following is a list of monitoring capabilities we carry.
