For hospital washer-disinfector and laundry validation accurate temperature measurement is required to meet HTM2030 and HSG[95]18 guidelines. Anville Instruments, manufacturers of the EaziVal 825 validation system, are the sole UK distributors for Tecnosoft PasteurDisk and StrerilDisk single channel data loggers for this application. Thermocouples can be used for temperature validation of multi-cabinet washer-disinfectors, but using a number of single channel data loggers is a cost-effective and faster alternative.

PasteurDisk single channel thermometer

This battery powered data logger is specially designed for monitoring temperature in severe operating environments up to 100°C. In a rugged stainless steel housing, with an external 'probe' temperature sensor, the PasterurDisk provides a low cost solution for accurate and reliable temperature monitoring of single chamber and multi-chamber washer-disinfectors, bed-pan washers and ,using an additional housing, laundry washing machines. Robust housings in ptfe or stainless steel are available for the harsh environment found in laundry machines.
