DLG-87799_SD Professional Humidity and Temperature Meter Data Logger SD Memory Record External / Internal Sensor

This product is currently sold out. Please contact us if will order in bulk.


Model : DLG-87799_SD 


This advanced professional datalogger is standalone and measures and stores relative humidity (RH) and air temperature (TA) over 20%~90%RH and 0~50°C(internal sensor) and -10~70°C (external sensor probe [direct contact]) measurement ranges. It directly records data onto standard SD memory. Each data set includes temperature, RH, time and date. Data gathered are saved in .txt file, these preformatted data can be uploaded or paste to Excel directly. This well made unit is extremely accurate with fast response times. Also, it has 2 temperature sensors, built-in internal sensor (measures ambient temperature) and external sensor probe (measures temperatures in water or fridge, etc.).
