Features: 

*Used the exclusive MICRO-COMPUTER LSI circuit and crystal time base to offer the high accuracy measurement & fast measuring time.
* Wide measuring range & high resolution.
* Digital display gives exact reading with no guessing or errors.
* The last values/max. values/min. values of both Humidity and Temperature will be automatically
stored in memory and can be displayed by turn.
* The use of durable, long-lasting components, including a strong, light weight ABS-plastic housingassures maintenance free performance for many years. The housing has been carefully shaped to fitcomfortably in either hand.
