Extech Instruments Corp.: DATALOGGER
The Model 446580 humidity/temperature datalogger measures from 10% to 95% rh with 3% accuracy via a capacitance sensor; temperature measurements, via a semiconductor sensor, range from -4° to 140°F (-20° to 60°C), says the company. Both humidity and temperature are displayed simultaneously. Data hold freezes the readings. The built-in memory stores up to 7,000 measurements at sample rates of 1 to 65 sec, the company says. Data with date and time is transferred to a PC via the RS-232 interface.
