HD206⦠/ HD226⦠and HD207⦠/ HD227⦠series data loggers are low-cost, rugged
instruments, for a long-term reliable monitoring of temperature and temperature/ relative humidity measurements. They are available in different versions: with or without LCD display,
with temperature sensor either inside or outside the instrument housing, or with cable connection. The analysis of acquired data is made using Delta Log2 software for Windows.
The datalogger functions of Start, Stop, Configuration, Data Download and Setting of storage interval are selectable either from keyboard or from a computer. Through a computer, you can define a password to enable the access to configuration data.
Typical applications are: monitoring of temperature/ humidity during transportation, storage of fresh or frozen foods, fruit, vegetable products and flowers, pharmaceuticals, sensitive and photographic products, paper, explosives, as well as laboratory activities in general.
Configuration and data download to a PC are very easy: DeltaLog2 dedicated software guides the operator step by step.
SIT calibration certificates for all versions can be issued.
Excellent protection against atmospheric agents.
Temperature and relative humidity high accuracy all over the range.
Resolution: 0.1° C, 0.1% RH.
Sampling freely selectable by the user.
Manual control of acquisition start and stop either through a pushbutton or a clock.
Fast download of stored data.
240.000 data capacity on a single channel and 80.000 data capacity on three simultaneous
channels.
Flash memory for holding data storage even when the instrument is without battery or with battery low.
Battery replaceable by the user.
Indication of flat battery.
All models provide a visual indication while the instrument is acquiring.
