Temperature data logger for ultra low temperatures from -80°C up to 140°C with probe of various lengths
S-MicroW L Ultra Freeze is a data logger for ultra low temperatures from -80°C to 140°C (calibration from -40°C to 140°C) with 20, 100 mm or on demand length external probe (probes cannot be switched) on a 5 mm base (base height is not counted for probe length), managed with Windows software and USB interface (DiskInterface HS, Multibay). Battery is user replaceable and the data logger is provided with an Accredia (NIST equivalent) traceable cetificate on 6 points.
The data logger looks like the S-MicroW L standard but it includes a calibration from -40°C. With calibration from -40°C it can be used also at -80°C with an accuracy within ± 0,5 °C within range -80 °C ÷ -40 °C. If -80°C is requested to be on the certificate, an extra calibration point for very low temperatures must be purchased. It is particularly indicated for monitoring and validation of ultra freezers.
The other versions of the data logger are:
- S-MicroW L: with rigid probe of different lengths
- S-MicroW L Flexible: with flexible cable probe and rigid probe at the end
- S-MicroW L Bendable: with semi-rigi metal bendable probe and rigid probe at the end
For each version it is available the XL model too, S-MicroW XL Ultra Freeze, which has same diameter but is higher because it hosts a bigger battery for a longer life time.
There are also other models of high temperature data loggers, for pressure and humidity too.
Note: if used below -30°C, battery life will be highly reduced. Mission max duration at -80°C: 12 hours. Using the logger for long periods below -40°C will constantly reduce mission max duration. For longer missions purchase the -80°C special battery for S-MicroW L Ultra Freeze. With -80°C special battery mission max duration at -80°C with the special battery: 2 months. Using the logger for long periods below -40°C will constantly reduce mission max duration. Max temperature of use of the -80°C battery is 80°C: REMOVE IT AND USE STANDARD BATTERY TO USE THE LOGGER IN AUTOCLVE OR ABOVE 80°C.
