30 Day logger
30 Day logger (Product Code: SLE/CCE/023) is an electronic temperature logger used to monitor vaccine refrigerators and freezers and show whether storage stayed in range over the previous 30 days. Cold chain staff read a simple OK or ALARM display for each of those days, backed by ±0.5°C accuracy and an internal sensor. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as part of its range of digital measuring instruments for health and laboratory buyers.

What Is the 30 Day Logger Used For?
The logger sits inside the vaccine refrigerator or freezer, close to the stock, and stays there. Rather than relying only on manual thermometer readings, staff check the LCD for an OK or ALARM mark covering each of the previous 30 days, so overnight or weekend temperature problems no longer go unnoticed.
The internal sensor and IP64 rating suit the cold, damp conditions inside appliances, and because the lithium coin cell is sealed in, there is no battery to change during its 66-month life. When an ALARM appears, follow your programme's rules for checking the affected vaccines. Among test and measurement instruments in India used for cold chain monitoring, its plain OK/ALARM readout is easy for staff at every level to interpret.
