The Min-Max and Min-MaxPlus are reliable and cost-effective digital thermometers with real-time LCD display and the Plus model features an external probe. The small thumb-size format fits easily into small spaces. Both Min/Max thermometers include a redundant roll over memory allowing for review of up to 30 days of past data. Should you record a critical Min/Max reading the unit can then be sent to Scigiene for Data Extraction and a Compliance/Validation report. The Min/Max thermometers can ideally be used in labs and clinics.
