Blue Jay Electronic provide temperature & humidity logger solution, build on our temp. & RH controller can control environment condition and record the temp. vibration. The time interval is set by programming can be from 1 second to 2 hours. Use EEPROM s which can store up to 40,000 measurements. This could be one measurement every 30 seconds for 11 days for example. The control function with completed FUZZY algorithm provides very precise of temperature & humidity monitor. FUZZY algorithm control fan or heater to maintain sensible & latent capacity follows temperature curve by automatically. Display unit can show environment temperature and humidity as per configure by user. The user also can adjust environment condition very easily. Function & Feature ·DIN(48X48mm) or panel mounting ·High measurement indication and control accuracy 0.5?? and 3% RH ·Heat/Cool control and PID control mode ·All settings except time maintained permanently in non-volatile memory until changed by user ·Built-in digital filter reduce interfere ·Self calibration technology, keep stabilization ·Two line LED display show the data Independent, prevent dazzle, highly visible display ·Simple 4-Button user interface ·Switching power supply and low consumption ·Use large capacity relay ·RS 485 interface, easy to get raw data
